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 premium 2.5mm IR board lens is independently developed and manufactured by BOSHI Optical Technology. It is an M12 wide angle lens tailored for 1/2.7” image sensors. This ultra‑wide surveillance component delivers an impressive 168.8° diagonal field of view, which effectively removes monitoring blind spots for multiple visual devices. Adopting F2.4 large aperture structure, this miniature camera lens delivers strong light‑gathering capacity to capture crisp footage both day and night. Benefiting from IR corrected optical design, this fixed‑focal security lens can sustain steady image clarity under visible‑light scenarios as well as infrared night‑vision conditions. Its compact TTL dimension hits 23.0±0.2mm, and such feature enables easy integration inside slim and compact camera modules. BOSHI Optical Technology executes comprehensive optical performance tests during mass production so every finished M12 wide angle lens can maintain dependable output. As a cost‑effective wide angle monitoring lens, this product gains extensive deployment within smart security cameras, robotic embedded vision equipment, vehicle auxiliary cameras and various intelligent visual terminals.
