The PL-1645F-M12 from BOSHI Optical Technology is a compact 16mm focal length, F4.5 aperture fixed-focal lens engineered specifically for 1/2" format sensors. Designed with a 4-glass-element all-glass construction, this M12-mount lens delivers a 28.3° diagonal field of view and supports a maximum image circle of Ø8.5mm, making it an ideal match for 1/2" and smaller imagers in space-constrained vision systems. With a mechanical back focal length of 3.65mm and total track length of just 28.65mm, the PL-1645F-M12 integrates seamlessly into board-level camera modules for industrial inspection, biometric identification, and embedded imaging applications. BOSHI Optical Technology has optimized this 16mm F4.5 lens for superior edge-to-edge illumination, achieving 95% relative illumination and ultra-low TV distortion of -0.25%, ensuring faithful image reproduction even in high-contrast scenes. The chief ray angle is strictly controlled below 8°, minimizing vignetting and color shift when paired with modern CMOS sensors. Whether used in factory automation, logistics barcode readers, or medical imaging devices, this 1/2" sensor lens offers a balanced blend of resolution, compactness, and cost-effectiveness. Trust BOSHI Optical Technology to deliver reliable optical performance for your next-generation vision product, with the PL-1645F-M12 setting the benchmark for precision in the M12 lens category.

Injection molding of capsule shell, has a high transmittance optical effect, small size, light weight, and is made of corrosion-resistant polymer material, which does not rupture.

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.
