The LINOS Zoom- and 

Microscope Optics 

LINOS offers a large selection of zoom 

systems, microscopes, lenses, and eyepieces. 

The Optem Zoom lenses and probing microscopes 

(A-Zoom series) were originally developed 

for applications in industrial microelectronics 

image processing and for fully 

automated quality control. High precision 

and flexibility open a broad range of applications 

in many areas, such as solar panel 

production or biotechnology. 

Infinity corrected microscope lenses with 

long working distance and/or high resolution 

are important for all applications in the 

field of microscopy. For that reason we offer 

highly sophisticated lenses with many optical 

advantages and at very competitive prices. 

The LINOS mirror lens mag.x is designed for 

the entire wavelength range from 190 to 

900 nm. The optimized Schwarzschild design 

guarantees excellent imaging performance. 

The broadband anti-reflective coated orthoscopic 

eyepieces from LINOS feature extremely 

low distortion. 

Our quality criteria: 

• Many years of experience in optical 

design 

• Sophisticated coating techniques 

• Best imaging performance 

• Extremely low distortion 

• Latest high-precision mounting 

technologies

The mounting bracket enables the

as well as a central M6 threaded bore 

hole, for fastening.

Mounting Bracket OPTEM G02 4347 000 

Lighting Kit 

Lighting Kits connect the G04 5365 000 

Light Guide to the coaxial lighting unit in 

the Optem Zoom System. This lighting 

technique is ideal for objects with 

mirrored or highly reflective surfaces. 

The light is produced by a diffuse light 

field and diverted to the object by a 50 

percent transmissive mirror, so that the 

axis of illumination lies precisely on the 

optical axis of the camera. 

The light guide with its standard 

connector is the interface to all cold light 

sources (LED, halogen, Xenon and HBO) 

in the LINOS catalog. Thus it covers a 

broad lighting spectrum, from UV to the 

near-infrared range, or a color temperature 

range from 3000 °K to 6500 °K. 

For shadowless and homogenous illumination 

of objects with matte or only 

slightly reflective surfaces, ring lights are 

the best choice. Adapters for the ring 

lights in the LINOS catalog are listed with 

the Optem lighting accessories.

While the coaxial lighting technique is 

well suited for mirrored or highly

equip the Optem Zoom systems with ring 

light illumination. This lighting method is 

ideal for shadowless, homo genous 

illumination of objects with matte or 

only slightly reflective surfaces. With a 

ring light adapter, both the glass fiber 

ring lights in the LINOS Catalog and the 

LED ring lights with an inner diameter of 

66 mm can be mounted in the zoom 

system. Thus a broad lighting spectrum is 

covered, from UV to the near-infrared 

range, or a color temper ature range 

from 3000 °K to 6500 °K.

Reflecting Objective mag.x ® RO 20X / 0.35 

Qioptiq new reflecting objective mag.x® 

RO 20X / 0.35 provides outstanding 

imaging. 

As a result of using reflective optics, the 

objective is free from chromatic aberrations 

and is compatible across broadband 

UV - VIS applications. The optimized 

Schwarz schild design, consisting of a 

large concave primary mirror and a small 

convex secondary mirror, provides an 

optical system which is corrected for 

primary spherical aberration, primary 

coma and primary astigmatism. This 

design offers near diffraction-limited 

performance over the full wavelength 

range of the chosen coating. For this 

reasons the objective is ideally suited for 

applications which require high transmission 

and excellent resolution over a 

broad wavelength range at a long 

working distance. 

The main applications for this objective 

are FTIR spectroscopy, photolithography, 

ellipsometery and semiconductor inspection. 

Qioptiq mag.x® reflecting objectives are 

mounted in a finely machined body with 

the universal RMS-mount thread.
