Jos. Schneider Optische Werke GmbH has introduced its Xenoplan and Cinegon compact C-mount lenses for use with high-resolution megapixel CCD and CMOS cameras in machine vision applications. Built-in filter threads that simplify filter mounting have been added to lenses having focal lengths from 4.8 to 50 mm and featuring image circles with 2/3- or 1-in. formats and measuring up to 22 mm diagonally. An enhanced-precision iris improves control of gray-scale calibration, and a focus mechanism enables fine-focus adjustment and locking without backlash. The lenses have a broadband antireflection coating that reduces stray light, maximizing transmission and improving image contrast.
