This high-performance M12 fisheye lens is engineered by ShangHai SILK Optical Technology CO., LTD to deliver seamless panoramic monitoring with an ultra wide angle field of view. Designed for 1/2.7” image sensors, this ultra wide angle lens adopts a mature 2G3P+IR optical structure, balancing compact size and all-day imaging capacity. It features a 2.18mm effective focal length, F2.4 fixed aperture and 185° diagonal field of view, enabling single-camera wide-area coverage without stitching multiple cameras. As a reliable IR corrected lens, it maintains consistent image quality under visible and infrared light for day-night surveillance scenarios. The total track length is controlled at 14.5±0.2mm, supporting miniaturized camera module integration. Strict optical calibration delivers 46.0% relative illumination and controlled CRA under 20.43°, greatly reducing vignetting and matching mainstream CMOS sensors. ShangHai SLIK Optical Technology CO., LTD provides stable mass production and customizable optical solutions for global clients using this mature panoramic lens platform.

Distortionless Optical M12 Lens is 4.555mm distortion free 16 million pixel,Distortionless Optical M12 Lens Is match to 1/2.3 ", Distortionless Optical M12 Lens is scanning instrument MT9J003 special lens M12 mount.

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.

xThe PL-2445D-M9 is a compact fixed-focal lens engineered by BOSHI Optical Technology for high-resolution industrial imaging. With a 24mm focal length and F/4.5 aperture, this lens delivers exceptional clarity and consistent brightness across a 1/2.5" sensor, covering a maximum image circle of Ø7.4mm. Its all-glass (3-element) construction ensures thermal stability and superior transmission, while the M9 thread mount (P0.35) provides reliable mechanical integration into space‑constrained systems. The lens offers a narrow field of view (16.7° diagonal) ideal for long‑distance inspection, with a TV distortion of merely -0.05% and relative illumination of 97.0% – values that guarantee faithful geometric reproduction and minimal vignetting. The chief ray angle (CRA) stays below 6.6°, ensuring excellent compatibility with modern sensor micro‑lens arrays. Whether deployed in automated optical inspection, precision metrology, or surveillance, this 24mm focal length lens from BOSHI Optical Technology maintains sharpness from center to edge. Its robust optical design supports consistent performance under varying temperatures, making it a dependable choice for OEM integrators who demand repeatable imaging quality without compromising on size or cost.
