Vacuum Optics Catalogue - March 2022

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.
