Fujinon HF50SA-1 Lens, Up to 5MP, 50mm Focal Length

HF50SA-1 Overview

Designed for factory automation and machine vision applications, the Fujinon HF50SA-1 high-resolution C-mount lens supports digital (machine vision) cameras up to 5 Megapixels and uses premium optics to achieve low distortion corner to corner performance. Requiring a minimum focusing range of only 400mm, this compact and robust lens is particularly suited for applications where highly detailed close-up imaging is a priority. It also incorporates a ring lock system which utilizes thumbscrews to prevent the focus and iris rings from shifting once they've been set.
