Designed for factory automation and machine vision applications, the Fujinon HF25SA-1 high resolution C-mount lens supports digital cameras up to 5 mega pixel and uses superior optics to achieve corner-to-corner performance with low distortion. Requiring a minimum focusing range of only 0.2 meter, this compact and robust lens features a rear focusing system and is particularly suited for applications where highly detailed close-up imaging is a priority. Additionally, this lens employs a ring lock system to prevent focus and iris shifting when used on vibrating machinery.
