The Schneider Optics Xenon-Emerald 2.8/28 Lens (F-Mount p/n: 21-1072685) is a large format 28 mm focal length lens covering up to 43.2 mm image circle, with V48-Mount or F-Mount options that was developed for cameras with 29 megapixel sensors. 

The low distortion Xenon-Emerald 2.8/28 lenses with an image circle diameter of 43.2 mm are compact, robust, lockable in distance and aperture. They are designed for close up range (S) and long range (L) and optimized for a uniform image quality over the whole sensor area.

The 400 to 1,000nm broadband coating makes the Xenon-Emerald 2.8/28 suitable for applications in the visible and near infrared spectrum. The variety of alternative mounts makes them even more flexible for a wide range of applications in machine vision, quality control, web inspection and other image processing applications.
