Developed by BOSHI Optical Technology, the PL‑1645F‑M12 is a compact fixed‑focus cone lens built around 16mm focal length and F4.5 specifications to serve 1/2" sensor imaging hardware. This M12 mount optical assembly adopts full‑glass four‑element structure, delivering 28.3°FOV alongside 8.5mm image circle to match 1/2" sensor and smaller image sensors for space‑limited board‑level camera optics systems. It reaches 95 percent high relative illumination and realizes low distortion performance with TV distortion value of ‑0.25 percent. Its mechanical back focal length measures 3.65 mm and overall total track length hits 28.65 mm for easy embedding into compact camera modules. Created for machine vision and other embedded imaging scenarios from industrial inspection to biometric identification, the lens from BOSHI Optical Technology tightly controls chief ray angle under 8 degrees to restrain vignetting and color shift when cooperating with mainstream CMOS sensors. It balances resolution, miniaturized dimension and cost efficiency, and fits factory automation, logistics barcode reading and medical imaging devices for stable and authentic image output.

This F1.0 25mm long wave infrared lens is developed and supplied by ShangHai SILK Optical Technology CO., LTD.
