Schneider-Kreuznach offers a highly sophisticated, new family of line scan lenses, called Xenon-Diamond lenses for large magnifications such as -2.6x or -3.5x.
They are optimized for the highest resolution and very high image quality when used with 12k scan lines with 5 μm pixel size (pitch) which means MTF@72 lp/ mm > 0.40 on the image side for an image size of 62.5 mm.
Actually Xenon-Diamond lenses can also be used for image sizes as large as 82 mm to also cover 16k/ 5 μm-pitch lines. As usual Xenon-Diamond lenses are compact, robust, and lockable in distance and apertures. The 400 to 1,000 nm broadband coating makes it suitable for applications in the visible and near-infrared spectrum.
The V-mount makes it easy to install and rotate into the desired azimuth position. For each magnification there are two lens versions: one regular type for use without beam splitter or with pellicle and one for use with a beam splitter prism made of BK 7 and a thickness of 25 mm.
