M12 Starlight Lens F1.6-6mm HD Security Monitoring Board Lens 1/2.7"，Low illumination.

Our F1.0 darklight lens 4mm demonstrates significant advantages in stray light suppression, edge imaging sharpness and light transmittance, with higher yield and better consistency. It can still clearly capture details in low-light conditions.

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.
