Many machine vision applications require images of very small objects to be captured at distances of only a few centimetres. Standard lenses are not always suitable for this type of application. By contrast, Schneider Kreuznach's precision lenses are perfectly suited to these situations because they are corrected for close-up work and benefit from low levels of image distortion.
For technical reasons, Schneider Kreuznach's Componon and Apo-Componon precision lenses are not built with a focussing mechanism, so when these lenses are used for image capture they require a focussing mechanism. To address this, Schneider Kreuznach developed the Unifoc 58 and Unifoc 76 focussing system which allows lens adjustment to suit any application.
