ZF-I: Modified Lenses for Industrial Applications

Carl Zeiss has significantly expanded its industrial lens portfolio.

OBERKOCHEN/Germany, 06.11.2008. The line of SLR lenses for industrial applications has now grown to seven models. Thus, a complete line of lenses is now available, which offers the right solution for most standard requirements in industrial applications.

The modern optical design of these lenses with fixed focal lengths ensures maximum image quality.

Professional industrial applications require reliable, constant settings. Therefore, the ZF lenses are available in a special industrial version. The f-stop and focus settings of the ZF-I lenses can be fixed. For this purpose, the lenses are supplied with five locking screws which enable reliable locking of the adjustments once they have been set. Measuring inaccuracies and errors are thus reduced, and there is no need to waste time checking the settings.

A special coating which guarantees a high transmission value for wavelengths up to 1,100 nanometers can be applied to enable photos in the near infrared range. The ZF-IR lenses from Carl Zeiss are suitable for use with special cameras (IR cameras without appropriate barrier filters). Fields of application for technical IR photography include forensic science.

All ZF lenses provide the proverbial performance, i.e. sharp image definition, color fidelity in accordance with ZEISS standards, stray light absorption, well-corrected distortion and no reflections. With their F-bayonet, they comply with the globally accepted standard for high-resolution industrial cameras featuring large-format image sensors. All lenses with focal lengths 18, 21, 25, 28, 35, 50 and 85 mm and the two macro lenses with 50 and 100 mm focal lengths are available as ZF-I or ZF-IR version on request.
