No perspective error for measurement applications

Optotelecentric lenses were developed for high-precision measurement applications in industrial image processing. The advantage of these high-quality optics lies in their bilateral telecentric imaging function (i.e. bi-telecentric function). Due to the spatial extension of the object-side telecentricity, three-dimensional objects are imaged without errors in perspective. Because of the image-side telecentricity, the system is far less dependent on the mechanical tolerances of the camera and exhibits a far more uniform projection onto the camera chip with zero vignetting.

Image of the same object: taken with an entocentric lens on the left and with a telecentric lens on the right. On the left, you can clearly see the perspective distortions caused by the diverging ray paths of the entocentric (normal) lens.

Bi-telecentric lenses

Our bi-telecentric lenses are optimized for C-mount cameras with chip sizes up to 2/3" and thus represent the ideal solution for measuring precision components - at the best price/performance ratio.
