Lenses by Carl Zeiss
Carl Zeiss produces a series of lenses with very high light efficiency, large image circles
and extraordinary contrast performance. All types provide a first-class mechanic and an
internal lens system completely based on glass. The full-metal focus adjustment
guarantees a precise and smooth-running use.
Beside the standard lenses there are also special versions available for industrial
applications. These types out of the ZF-I series are suitable to be used in harsh
environments and are e.g. specially protected against splash water and dust. The iris
and focus alignment can be fixed. For this all lenses are supplied with five fixing screws,
which can be used to secure the needed settings. Beside the classic image capturing
typical applications include also quality control, close range photogrammetry and the
complete area of machine vision.
For special applications in the infrared region the lenses of the ZF-IR series were developed. Here the internal used lenses are specially coated, so that they can be used with wavelenghts up to 1100nm. The focus range was of course adapted to this extended spectral range.
