BOSHI Optical Technology presents the PL-02934H-M12, a high performance wide angle fixed lens for 1/4" Image Sensor formats. With 2.9mm Focal Length and F3.4 Aperture, this Wide Angle Optical Lens delivers a 119° Field of View for broad scene coverage in tight spaces. The all glass construction supports thermal stability and consistent image quality. A controlled Chief Ray Angle below 6.63° reduces colour shading with modern CMOS sensors. The Compact Fixed Lens has an 8.9mm total track length and a 2.46mm mechanical back focal distance for M12 Lens Mount integration. BOSHI Optical Technology balances TV Distortion at about 14.27% barrel distortion, a typical value for wide angle optics that digital correction can address. Relative illumination is 30% at the edge for usable brightness in low light. This lens suits Surveillance and Automotive Imaging, embedded vision, security cameras, in vehicle surround view systems, and industrial inspection. The 2.9mm Focal Length and 119° Field of View support dashcams, doorbell cameras, and compact devices. The F3.4 Aperture provides useful depth of field from 0.3m to infinity.

This compact machine vision lens is manufactured by ShangHai SILK Optical Technology CO., LTD, optimized for 1/4” sensor with 2592*1944 resolution. Built with reliable optical layout, this mini board lens delivers steady imaging performance with 3.05mm focal length and F5.0 aperture. It supports a 4.8mm image circle and 72‑degree diagonal FOV, meeting the wide‑view requirement of compact imaging modules. The low distortion lens design keeps TV distortion below 1.5%, together with 650nm IRCF wavelength to filter unwanted infrared interference. Ultra‑short TTL at 3.6mm makes it fit for space‑constrained device integration. ShangHai SILK Optical Technology CO., LTD carries out strict optical inspection for each unit, ensuring consistent batch quality for mass‑production projects. This cost‑effective M5.5 mount optical component is ideal for small‑size embedded camera systems across multiple consumer and industrial scenarios.

Developed by BOSHI Optical Technology, the PL‑1645F‑M12 is a compact fixed‑focus cone lens built around 16mm focal length and F4.5 specifications to serve 1/2" sensor imaging hardware. This M12 mount optical assembly adopts full‑glass four‑element structure, delivering 28.3°FOV alongside 8.5mm image circle to match 1/2" sensor and smaller image sensors for space‑limited board‑level camera optics systems. It reaches 95 percent high relative illumination and realizes low distortion performance with TV distortion value of ‑0.25 percent. Its mechanical back focal length measures 3.65 mm and overall total track length hits 28.65 mm for easy embedding into compact camera modules. Created for machine vision and other embedded imaging scenarios from industrial inspection to biometric identification, the lens from BOSHI Optical Technology tightly controls chief ray angle under 8 degrees to restrain vignetting and color shift when cooperating with mainstream CMOS sensors. It balances resolution, miniaturized dimension and cost efficiency, and fits factory automation, logistics barcode reading and medical imaging devices for stable and authentic image output.

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.
