Carl Zeiss VISIONMES lenses are developed for crucial measuring tasks in industry and feature telecentric optics. For optical metrology at high precision telecentric optics are essential.  
With this type of objective lens the light is parallel over the whole object field and the image size will remain the same even if the objects position would vary.
Carl Zeiss offers telecentric lenses with outstanding image performance and extremely low distorsion for the purpose of imaging and/or measuring objects up to 300 mm diameter.
Distorsion up to 105 mm object size: 3 µm
Distorsion up to 300 mm object size: 5 µm
Every single lens is manufactured in Germany and quality tested with the accurateness you can expect from Carl Zeiss. Inspection certificate on request.

Measuring excellence:

• Extreme low distortion over the entire object field
• Fits to any standard CCD matrix via C-Mount.
• High information transfer rate for the use in CCD receivers
• Diffraction-limited imaging for maximum resolution
• High aperture for short exposure times
• Optimum adaptation of edge contour and depth of focus to the measuring object
• Low sensitivity to stray light
• Modular design permitting the highest flexibility
• Graduated object fields up to 300 mm diameter
