ShangHai SILK Optical Technology CO., LTD offers the M7 lens, a compact optical lens engineered for small format camera lens integration with 1/2.7" image sensors. This 6.2mm fixed focal lens adopts 4-group lens assembly design, delivering balanced imaging performance for miniature camera hardware. Boasting a maximum image circle of Ø7.0mm, this wide angle miniature lens supports diagonal 74° field‑of‑view to capture sufficient scene coverage. As a low CRA lens with chief ray angle below 15°, it perfectly matches common CMOS sensors and reduces vignetting risk, paired with 58.0% high relative illumination to maintain uniform brightness across the whole frame. Built with M7 compact mount, this surveillance optical lens features short total track length at 13.42±0.3mm, well‑suited for space‑constrained device housing. Manufactured by ShangHai SILK Optical Technology CO., LTD, this compact optical lens undergoes strict optical testing to guarantee consistent output for mass‑produced embedded vision devices.

We have designed and produced various specifications and applications of Endoscopic lens for domestic and foreign customers. Whether it's 4K or 3D, Lens for CMOS sensors such as 1/6 ", 1/7.5", 1/9 ", 1/11", 1/13 ", and 1/18".

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.
