Facilities
Torr Scientific relocated to a modern 410 m 2
factory in Bexhill-on-Sea, East Sussex in
August 2009. A 270 m 2 first floor extension
was completed in October 2011 increasing
floor space at the Sussex manufacturing
site to 690 m 2 . A second adjoining factory
and cleanroom was built in 2015 expanding
floor space to over 1200 m 2
Facilities
In response to demand from customers requiring
contamination free products for
UHV applications, the company invested in a
new 110 m 2 cleanroom to provide a laboratory
manufacturing facility in which thin-film
coatings and hermetic seals are processed,
and UHV and Optical instrumentation is assembled,
inspected and packed.
TSL took delivery of a new vacuum furnace
in August 2010. The furnace, supplied by
Specnow Ltd., has a hot zone four times larger
than previous furnaces at TSL. The system
incorporates Specnow’s latest Microlink
control system with data management and
logging. The investment was made to meet
growing demand for TSL fused silica and
sapphire UHV viewports and allow further
development of ceramic to metal seals.
A turntable and TIG welding cell has been set
up at Torr Scientific. All viewports are now
welded within the company allowing full
quality control over the complete viewport
manufacturing process. Weld rings in kovar,
stainless steel and non-magnetic materials
are welded in to 304L and 316LN flanges.

Facilities
All brazed and welded components are leak
tested using TSL’s Inficon mass spectrometer
helium leak tester.
Cleaning and assembly of UHV instrumentation
takes place in laminar flow cabinets in
cleanroom conditions.
The e-beam vacuum coating system is used
predominantly to process anti-reflective
coatings. TSL upgraded the electronic control
units on the e-beam system in 2009
in partnership with Ferrotec, specialists in
electron beam evaporator equipment. The
upgrade has improved efficiency and reliability
of the anti-reflecting coating process.
Viewports are coated to customer specified
wavelengths of application.
Torr Scientific invested in a new Perkin Elmer
UV/Vis/IR Spectrophotometer in January
2011. The spectrophotometer extends
the range at which the company is able to
measure both reflectance and transmission
to between 190 nm and 3.2 microns. The
instrument is used as an inspection tool
for incoming optics and for manufactured
UHV viewports with anti-reflective coatings
optimised for particular customer applications.
The spectrophotometer brings greater
quality control to the business and extended
TSL’s coating capability.

Facilities
Torr Scientific’s optical inspection capability
includes a recently acquired Zygo interferometer
surface profiler. The profiler enables
highly accurate non-destructive examination
of surfaces to check thicknesses and uniformity
of X-ray anode coatings and optical
flatness and seal structure of vacuum optics
manufactured at the company. The interferometer
brings a greater level of quality
control and alongside the existing UV-Vis-IR
spectrophotometer strengthens the company’s
optical and coating test facilities.
Facilities
Torr Scientific has extended its vacuum
window processing capabilities to include
production of glass to metal seals. The facility
also allows further development of the wide
range of vacuum optical components offered
by the company. OEM and non-standard
enquiries are also welcome. A new induction
heater has been added to the glass shop and
enables the company to develop its range
of glass vacuum windows, feedthroughs
and OEM requirements for encapsulation of
X-ray and photonic components. The induction
heater adds to the current vacuum
brazing techniques applied for production of
the vacuum optic range of products.
The Torr Scientific precision machine shop
houses an XYZ CNC/Manual mill and 50”
colchester lathe. In addition to welding, helium
leak testing, cleaning and inspection facilities,
the facility manufactures components
and small UHV chambers to custom design.
CAD Engineering drawings are produced
around customer requirements and issued
for customer approval before manufacturing
proceeds.

Product Introduction
Viewports
Torr Scientific manufactures a range of UHV viewports in CF, ISO or KF formats including a
variety of anti-reflective coatings to enhance performance. Materials include Kodial (borosilicate
glass), Quartz, Sapphire, MgF 2 , BaF 2 , CaF 2 , ZnSe, CVD diamond and Lead Glass. Non-magnetic
options and 316LN flanges are offered. Full transmission, dimensional, optical and temperature
specifications can be viewed on the viewport datasheets and standard price list. Custom designed
viewports, such as special assemblies to be able to insert microscopes or cameras in to vacuum
systems, can be quoted on request. The viewports are manufactured and coatings are processed
in cleanroom conditions.
Viewports with Anti-Reflective Coating
A range of anti-reflective coatings can be processed and optimised to customer specified wavelengths.
Theoretical reflectance curves can be supplied on request for particular window material
and wavelength combinations. Single 1QWOT ‘AR’ coatings, plus four-layer broadband ‘BBAR’
coatings for a wavelength range and two-layer ‘V’ coatings optimised for single wavelengths are
provided. A list of regular curves can be viewed on the Torr Scientific website. If there is a curve
listed which suits your application please reference it in your enquiry or order. The coatings are
processed on TSL’s eBeam system in cleanroom conditions and tested on a state of the art UV-Vis
spectrophotometer.
Glass to Metal Seals & Glass-Working
Torr Scientific has extended its vacuum window processing capabilities to include production of
glass to metal seals. The facility will also allow further development of the wide range of vacuum
optical components offered by the company. A new induction heater is now in operation and
glass-working lathes, ovens and test equipment are also housed in the glass department. The
operators have many years’ experience in the production of glass products for vacuum and electron
optical devices. The recently formed department will enable the company to develop glass
vacuum windows, feedthroughs and X-ray tube encapsulations in addition to the current vacuum
brazing techniques applied for production of the vacuum optic range of products. All Kodial glass
viewports are now produced in-house and enquiries for custom requirements for glass-working
and glass to metal seals are welcomed.

Product Introduction
Optics
Torr Scientific has incorporated optical quality windows in to a wide range of viewports in response
to growing demand for scientists carrying out laser experimentation within UHV systems.
The company is also able to supply polished optics in a variety of forms and materials. Standard
viewport windows can be offered as well as optics to custom specification. Precise surface
qualities and optical specifications can be quoted. A Perkin Elmer UV/Vis/IR Spectrophotometer
enables the company to measure both reflectance and transmission to between 190nm and 3.2
microns. The instrument is used as an inspection tool for incoming optics and for manufactured
UHV viewports with anti-reflective coatings optimised for particular customer applications.
CVD Diamond
Torr Scientific is the European agent for optical and thermal CVD diamond processed at The
Plasma Laboratory, Hebei Institute of Laser in China. Natural diamond has always been of extreme
scientific interest due to its unmatched properties including hardness, thermal conductivity,
broadband transparency, chemical inertness and high temperature stability. However, the cost
of natural diamond substrates is prohibitive in most cases. CVD processes have been developed
to the point where economical artificial diamond substrates are now readily available. Torr Scientific
is offering CVD diamond substrates in various shapes for use in applications such as thermal
mounts and laser windows as well as sealed into vacuum viewport assemblies for high vacuum
applications. The CVD diamond performance is very close to that of natural diamond, so our customers
can now take advantage of thermal conductivity that is five times that of copper and high
transparency for optical wavelengths that range from 225 nanometers to beyond 100 microns.
Ceramic Products and Feedthroughs
Ceramic to metal seals are brazed in TSL’s vacuum furnace in cleanroon conditions. A range
of ceramic breaks is under development and electrical feedthroughs, multi-pin, BNC and SHV,
are offered in this catalogue. Ceramic parts and seals are also used in custom manufactured
feedthrough and anode assemblies for OEM customers.
Phosphor Screens
Torr Scientific produces a range of RHEED screens which are processed using kodial glass zero
length viewports with kovar weld rings and options of 304L or 316LN CF flanges. P22 yellow green
phosphor is supplied as standard and other phosphors including P11, P43 and P46 can be
supplied on request. Options with additional 6mm thick lead glass discs for X-Ray protection are
also offered. Screens can be prepared to customer design including phosphor layers directly on
to lead glass windows. RHEED, Reflection High Energy Electron Diffraction, is a typical application
used as a structural probe during material growth and deposition in Molecular Beam Epitaxy.
Torr Scientific also refurbishes LEED screens and processes custom specific phosphor screens on
various substrates, typically glass and lead glass.

Specification
Torr Scientific fused silica viewports are offered in CF, ISO and KF flange styles. The viewports comprise
a high purity laser quality fused silica optic with precise flatness, parallelism, scratch and dig
specifications. The ultra high vacuum (UHV) CF versions are offered using high grade 304L or 316LN
stainless steel flanges. Non-magnetic viewports are offered for low energy applications or surface
science applications needing low magnetic fields. The non-magnetic viewports use a non-magnetic
weld ring instead of the regular kovar weld ring. Flanges in 304L stainless steel are used for the high
vacuum KF and ISO viewports. TSL viewports are manufactured in cleanroom conditions and helium
leak tested, cleaned and packed to UHV standards. The rugged construction of the fused silica
viewports allows repeated bake-out with UHV performance, whilst the window offers broadband
optical transmission through deep UV, visible to near infra-red. Various anti-reflective coatings to
match customer reflectance requirements are processed at TSL and available as options listed in
the AR coated viewport section of the catalogue. Laser viewports with a VAR coating optimised
for specific customer specified laser wavelength, reducing reflectance to below 0.5% per face, are
also offered. Non-standard viewports can be manufactured on request, including re-entrant style
microscope/camera viewports. Annealed copper gaskets and other component accessories are also

Viewports
Torr Scientific fused silica re-entrant viewports are typically used for inserting microscopes or cameras
in to UHV/Vacuum systems. The re-entrant viewports are offered in CF flanges as standard, but
custom designed viewports can be manufactured using ISO and KF flange styles on request. The
viewports comprise a high purity laser quality fused silica optic with precise flatness, parallelism,
scratch and dig specifications which are vacuum brazed in to a kovar weld ring to form an optic
assembly. The optic assemblies are TIG welded in to the tube assembly and are helium leak tested
and cleaned for ultra high vacuum (UHV) conditions. The CF versions are offered using 304L stainless
steel flanges, but 316LN flanges can be offered on request. The rugged construction of the
fused silica viewports allows repeated bake-out with UHV performance, whilst the window offers
broadband optical transmission through deep UV, visible to near infra-red. Various anti-reflective
coatings to match customer reflectance requirements are processed at TSL and available as options.
Laser viewports with a VAR coating optimised for specific customer specified laser wavelength,
reducing reflectance to below 0.5% per face, are also offered. Please advise the wavelength or
wavelength ranges of your application and a reflectance curve will be prepared. Annealed copper
gaskets and other component accessories are also supplied by TSL. Please contact Torr Scientific if

Torr Scientific sapphire viewports are offered in CF, ISO and KF flange styles. The viewports comprise a high
quality optic with precise flatness, parallelism, scratch and dig specifications. The single crystal sapphire windows
have excellent optical, physical and chemical properties. The hardest of the oxide crystals, sapphire retains
its high strength at high temperatures. Sapphire has a low coefficient of thermal expansion and low fluorescence,
good resistance to thermal shock and scratching making this an excellent material for IR transmitting
optics and robust applications. C-cut sapphire is selected for Torr Scientific sapphire viewports to minimise the
effects of birefringence. The ultra high vacuum (UHV) CF versions are offered using high grade 304L or 316LN
stainless steel flanges. Non-magnetic viewports are offered for low energy applications or surface science applications
needing low magnetic fields. The non-magnetic viewports use a non-magnetic weld ring instead of
the regular kovar weld ring. Flanges in 304L stainless steel are used for the high vacuum KF and ISO viewports.
TSL viewports are manufactured in cleanroom conditions and helium leak tested, cleaned and packed to UHV
standards. The rugged construction of the sapphire viewports allows repeated bake-out to 200 °C with UHV
performance, whilst the window offers broadband optical transmission through vacuum UV, visible to near
infra-red. Various anti-reflective coatings to match customer reflectance requirements are processed at TSL
and available as options listed in the AR coated viewport data sheets. Non-standard viewports can be manufactured
on request, including re-entrant style microscope/camera viewports. Annealed copper gaskets and
other component accessories are also supplied by TSL.

Torr Scientific Z-Cut natural quartz viewports are offered in CF, ISO and KF flange styles. The viewports
comprise a high quality natural quartz optic with precise flatness, parallelism, scratch and dig specifications.
One of the best materials for transmission of wavelengths above 50 µm is z-cut crystal quartz,
so z-cut quartz windows are popular as THz windows. It is important that z-cut crystal quartz windows
are also transparent in the visible spectrum allowing easy adjustment with a HeNe laser and do not
change the state of light polarization. Z-cut quartz also has excellent transparency in the vacuum UV
portion of the spectrum and is therefore a popular window material for use in UV spectroscopy and
UV lithography. The ultra high vacuum (UHV) CF versions are offered using high grade 304L or 316LN
stainless steel flanges. Non-magnetic viewports are offered for low energy applications or surface science
applications needing low magnetic fields. The non-magnetic viewports use a non-magnetic weld
ring instead of the regular kovar weld ring. Flanges in 304L stainless steel are used for the high vacuum
KF and ISO viewports. TSL viewports are manufactured in cleanroom conditions and helium leak tested,
cleaned and packed to UHV standards. The rugged construction of the quartz viewports allows bake-out
to a maximum of 120 °C with UHV performance. Options with anti-reflective coatings are also offered.
Non-standard viewports can be manufactured on request, including re-entrant style microscope/camera
viewports. Annealed copper gaskets and other component accessories are also supplied by TSL.

Reflectance
Torr Scientific laser viewports are offered with a two-layer ‘VAR’ anti-reflective coating on both sides
of the window optimised to a customer specified laser wavelength. The coating reduces reflection
to below 0.5% per face or 1% total at the wavelength specified. Please advise the laser wavelength
with your enquiry or order. Wavelengths between 240 nm and 1550 nm can be accepted as standard,
although coatings for other wavelengths can be quoted on request. Viewports with coatings
for a wavelength range can also be offered. The viewports comprise a high purity laser quality fused
silica optic with precise flatness, parallelism, scratch and dig specifications. The ultra high vacuum
(UHV) CF versions are offered using high grade 304L or 316LN stainless steel flanges. Non-magnetic
viewports are offered for low energy applications or surface science applications needing low
magnetic fields. The non-magnetic viewports use a non-magnetic weld ring instead of the regular
kovar weld ring. TSL viewports are manufactured in clean room conditions and helium leak tested,
cleaned and packed to UHV standards. The rugged construction of the fused silica viewports allows
repeated bake-out with UHV performance, whilst the window offers broadband optical transmission
through deep UV, visible to near infra-red. Non-standard viewports can be manufactured on
request, including re-entrant style microscope/camera viewports. Annealed copper gaskets and
other component accessories are also supplied by TSL.

Fused Silica UHV Viewports
with Broadband Anti-Reflective Coatings
Fused Silica UHV
Viewports with Broadband
Anti-Reflective
Coatings
Torr Scientific fused silica viewports are offered with a four-layer broadband anti-reflective (BBAR)
coating on both sides of the window optimised to a customer specified laser wavelength range.
In many cases, the coating reduces reflection to below 0.5% per face or 1% total at the key wavelengths
specified. Please advise the important wavelengths or wavelength range with your enquiry
or order. Wavelength ranges between 240 nm and 1550 nm can be accepted as standard, although
coatings for other wavelength ranges can be quoted on request. Viewports with ‘V’ coatings for a
single wavelength for laser applications are also offered. The viewports comprise a high purity laser
quality fused silica optic with precise flatness, parallelism, scratch and dig specifications. The ultra
high vacuum (UHV) CF versions are offered using high grade 304L or 316LN stainless steel flanges.
Non-magnetic viewports are offered for low energy applications or surface science applications
needing low magnetic fields. The non-magnetic viewports use a non-magnetic weld ring instead of
the regular kovar weld ring. TSL viewports are manufactured in cleanroom conditions and helium
leak tested, cleaned and packed to UHV standards. The rugged construction of the fused silica
viewports allows repeated bake-out with UHV performance, whilst the window offers broadband
optical transmission through deep UV, visible to near infra-red. Non-standard viewports can be
manufactured on request, including re-entrant style microscope/camera viewports. Annealed copper
gaskets and other component accessories are also supplied by TSL.

Torr Scientific Kodial viewports are offered with a single 1 x QWOT MgF2 layer anti-reflective (AR)
coating on both sides of the window optimised to a customer specified wavelength range. Please
advise the important wavelengths or wavelength range with your enquiry or order. Wavelength
ranges between 190 nm and 1550 nm can be accepted as standard, although coatings for other
wavelength ranges can be quoted on request. Viewports with ‘V’ coatings for a single wavelength
applications and four-layer broadband low reflectance ‘BBAR’ coatings are also offered.
Torr Scientific Kodial viewports are offered in CF, ISO and KF flange styles. The viewports comprise a
borosilicate glass optic which is sealed to a Kovar weld ring using an induction heater process. The
optic assemblies are TIG welded in to flanges and are helium leak tested and cleaned for ultra high
vacuum (UHV) conditions. The CF versions are offered using 304L or 316LN stainless steel flanges.
Flanges in 304L stainless steel are used for the high vacuum KF and ISO viewports. The rugged
construction of the Kodial viewports allows repeated bake-out with UHV performance, whilst the
window offers broadband optical transmission from the visible to near infra-red. Anti-reflective
coatings to match customer reflectance requirements are also processed at TSL. Please advise the
wavelength or wavelength ranges of your application and a reflectance curve will be prepared.
Non-standard viewports can be manufactured on request, including re-entrant style microscope/
camera viewports. Annealed copper gaskets and other component accessories are also supplied by
TSL.

Viewport Shutters
Torr Scientific offers a range of viewport shutters to protect system windows during process, such
as vacuum deposition. Utilisting the magnetically-coupled MagiDrive rotary feedthroughs for the
shutter actuation, the range can be actuated manually or pneumatically, where remote control is
required. The MagiDrive’s low stray magnetic field ensures compatibility with RHEED measurements.
The range also includes the unique ‘AutoClose’ window. Viewport shutters are available on
four flange sizes from CF38 to CF150. Pneumatic actuated shutters and 100% coverage options can
be quoted on request.

Manual Actuation
Manually actuated viewport shutters are fitted with an external friction control system, ensuring
the blade remains in the desired position without the need for position locks.

Manual ‘AutoClose’ shutters
The unique ‘AutoClose’ shutter safeguards viewport windows from accidental deposition. It
allows end-users to manually open the shutter for viewing, but upon release automatically closes,
protecting the window from accidental coating. ‘AutoClose’ motion is driven by an inherent
position bias with intrinsic deceleration. The ‘AutoClose’ prevents the costly and time-consuming
requirement to break vacuum in order to replace/clean windows accidentally coated. This is
particularly undesirable for UHV systems. ‘AutoClose’ shutters can be mounted in any orientation
and are bakeable to 250 °C

Torr Scientific has incorporated optical quality windows in
to a wide range of viewports in response to growing demand
for scientists carrying out laser experimentation
within UHV systems. The company is also able to supply
polished optics in a variety of forms and materials. Standard
viewport windows can be offered as well as optics to
custom specification. Precise surface qualities and optical
specifications can be quoted.
Torr Scientific invested in a new Perkin Elmer UV/Vis/IR
Spectrophotometer in January 2011. The spectrophotometer
extends the range at which the company is able to
measure both reflectance and transmission to between
190nm and 3.2 microns. The instrument will be used as an
inspection tool for incoming optics and for manufactured
UHV viewports with anti-reflective coatings optimised for
particular customer applications. The spectrophotometer
brings greater quality control to the business and will extend
TSL’s coating capability.
Optics
The e-beam vacuum coating system is used predominantly
to process anti-reflective coatings. TSL upgraded the electronic
control units on the e-beam system in 2009 in partnership
with Ferrotec, specialists in electron beam evaporator
equipment. The upgrade has improved efficiency and
reliability of the anti-reflecting coating process. Viewports
are coated to customer specified wavelengths of application.
Below are examples of reflectance curves for a BBAR
broadband coating to cater for a wavelength range and for
a VAR coating optimised for a single wavelength typically
used for single laser applications.

Optics
Fused Silica
Fused Silica is a high purity synthetic
silicon dioxide. This noncrystalline,
colourless, silica glass has excellent
optical qualities and broadband optical
transmission through deep UV,
visible to near infra-red. Various antireflective
coatings to match customer
reflectance requirements are processed
at TSL and can be offered on
request.
Quartz Natural Z-Cut
Optics
The mineral quartz, which is a form
of crystalline silicon dioxide is birefringent
and the Z-axis is the optic
axis. This Z-cut quartz is commonly
used in optical applications. The material
offers extended broadband optical
transmission through deep UV,
visible to near infra-red.
Sapphire
Sapphire optics offer broadband optical
transmission through UV, visible
to near infra-red. The single crystal
sapphire optics have excellent optical,
physical and chemical properties.
The hardest of the oxide crystals, sapphire
retains its high strength at high
temperatures. Various anti-reflective
coatings to match customer reflectance
requirements are processed at
TSL and can be offered on request.
Magnesium Fluoride
Magnesium Fluoride transmits well
into the VUV region and is used
mostly for UV optics and is excellent
for Excimer laser applications. Magnesium
Fluoride is a tough material
and is slightly birefringent. Special
AR coated optics can be offered on
request.

Optics
Calcium Fluoride
Calcium Fluoride has widespread
IR applications and is also useful in
the UV and as UV Excimer laser windows.
Degradation due to moisture
in the atmosphere is minimal and
polished surfaces may be expected
to withstand several years exposure
to normal atmospheric conditions.
Low solubility and wide transmission
makes this material useful for many
applications. Special AR coated optics
can be offered on request.
Barium Fluoride
Barium Fluoride is used for applications
in the IR and is often used as a
viewport window for thermography.
Barium Fluoride cleaves easily and is
susceptible to thermal shock.
Optics
Zinc Selenide
Zinc Selenide optics are used widely
as IR windows. Zinc Selenide is one
of the materials of choice for CO 2 laser
optics operating at 10.6 μm. Optics
with anti-reflective coatings can
also be offered on request.
CVD processes have been developed
to the point where economical artificial
diamond substrates are now
readily available. The CVD diamond
performance is close to that of natural
diamond, so customers can now
take advantage of thermal conductivity
that is five times that of copper
and high transparency for optical
wavelengths that range from 225
nanometers to beyond 100 microns.

Filter Wheels
Torr Scientific manufactures Attenuation Filter Wheels in a range of sizes from 50 mm to 120 mm
diameter and with differing optical densities 0-1, 0-2 and 0-3. These filters are useful as beam splitters
and for applications requiring variable light attenuation in a continuous analogue mode, such
as in spectrophotometers and laser measuring systems. Laser quality fused silica is used for UV/VIS/
NIR applications and for its thermal stability. All filter wheels are manufactured to tight tolerances
especially parallelism to minimise beam movement with rotation. Specially designed items can also
be accommodated on request. Each filter wheel is supplied with a test certificate - typical data for a
non-standard density of 2.25 stays well within the specified linearity tolerance of +/- 6%.

CVD Diamond
The CVD diamond performance is very close to that of natural
diamond, so our customers can now take advantage
of thermal conductivity that is five times that of copper in
contrast to metals, where heat is conducted by electrons,
lattice vibrations are responsible for the high thermal conductivity
of diamond. Nowadays CVD diamond made by the
laboratory is used as mounts for high-power integrated circuits
and laser diodes. CVD diamond also has high transparency
for optical wavelengths that range from 225 nanometers
to beyond 100 microns. The broadband optical transparency,
high thermal conductivity and hardness make diamond an
ideal choice for highly demanding window applications such
as high-power IR laser windows, high-power microwave windows
and durable windows for aggressive environments.
The CVD diamond has the following benefits:
· Exceptional broadband infrared transparency
· Transparency in the optical and ultraviolet spectrum
· Excellent thermal conductivity
· Low scatter in infrared
· High fracture strength
· Low thermal expansion coefficient
Please see the viewports section for UHV flange mounted
options. Please contact TSL to request quotations for your specific
applications.
