MARCH 24, 2009--With its chromatic aberration correction, the Distagon T* 2,8/21 ZF lens for industrial image processing enables results without color fringes even in difficult light conditions in production halls. The lens performance is supported by the T* coating and optimum flare suppression. The shortest distance setting of 0.22 m is appropriate for near-range photogrammetry or optical measurement of components. The Distagon T* 2.8/21 ZF offers low-distortion, sharp images from infinity up to the near range.

PRESS RELEASE
New Lens for Image Processing in Industrial Applications
Carl Zeiss Distagon T* 2,8/21 ZF
OBERKOCHEN/Germany - March 20, 2009.
The new lens from Carl Zeiss for image processing in industrial applications, the Distagon T* 2,8/21 ZF, establishes new standards: thanks to its outstanding correction of chromatic aberration, the Distagon T* 2,8/21 ZF enables results without color fringes even in the difficult light conditions in production halls. This is supported by the T* coating and the optimum flare suppression. The Distagon T* 2,8/21 ZF is thus the perfect lens for applications with high optical requirements. Whether precision with fast running processes or color and structure accuracy - the Distagon T* 2,8/21 ZF provides reliable measuring results.
Many industrial imaging applications demand more than just outstanding imaging performance. The shortest distance setting of only 0.22 meters is beneficial for near-range photogrammetry or the optical measurement of components. The Distagon T* 2.8/21 ZF also offers low-distortion, sharp images from infinity up to the near range - even in difficult light conditions.
The sales price of the Carl Zeiss Distagon T* 2.8/21 ZF is EUR1,260 (excluding VAT). The Distagon T* 2,8/21 ZF will also be available as a ZF-I version,including locking screws for the focus and aperture ring. The sales price is EUR1,410 (excluding VAT).
