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.
