This premium 2.5mm IR board lens is developed and produced by ShangHai SILK Optical Technology CO., LTD. As an M12 wide angle lens built for 1/2.7” image sensors, this ultra wide surveillance lens delivers a stunning 168.8° diagonal field of view to eliminate monitoring blind spots for various visual equipment. Featuring F2.4 large aperture design, this F2.4 miniature camera lens ensures outstanding light gathering capability to deliver sharp footage day and night. Equipped with IR correction optical design, the fixed focal security lens maintains consistent clarity under visible light and infrared night vision environments. With compact TTL dimension of 23.0±0.2mm, this panoramic board camera lens is easy to integrate into slim, compact camera modules. ShangHai SLIK Optical Technology CO., LTD carries out strict optical performance testing during mass production to guarantee stable quality for every M12 wide angle lens. It serves as a cost-effective wide angle monitoring lens widely adopted in smart security cameras, robotic embedded vision, vehicle auxiliary cameras and intelligent visual terminals.

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.

19mm F1.0 M22 12um AR Lens Long-wave Infrared Thermal Imaging Lens is a 13mm F1.0 LWIR thermal lens working at 8–12μm, optimized for 640×512 (12μm pitch) uncooled infrared detectors. Core Strengths: 1.Ultra-large F1.0 aperture plus ≥90% high-transmittance AR coating delivers top-tier sensitivity for long-distance faint heat source detection; 2.Extra-high relative illumination ≥86% ensures uniform frame brightness and error-free temperature measurement at image edges; 3.Minimum focus distance of 0.5m supports close-up inspection of tiny components, while infinity focusing enables long-range patrol missions; 4.IP67 front lens protection and -40℃~+80℃ wide temperature range enable all-weather outdoor deployment without extra protective housings; 5.19mm focal length with narrow 22.85° horizontal FOV magnifies distant targets for clear long-distance defect identification. Main Applications: Long-distance power grid inspection, photovoltaic hot spot detection, precision industrial equipment predictive maintenance, long-range border & factory perimeter security, railway contact line monitoring, early forest fire warning. Important Note: Noticeable barrel distortion (<-10%) makes it perfect for temperature detection and target identification, but not recommended for high-precision dimensional measurement tasks.
