Our4mm 4MP FullColor F1.0 blacklight Starlight M12 lens 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.

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.

Manufactured by BOSHI Optical Technology, this premium long‑wave infrared lens delivers outstanding imaging performance as a high‑end uncooled thermal lens solution. This thermal imaging lens features 9.1mm focal length together with ultra‑large F1.0 aperture and pairs well with 640×512 detector with 12μm pixel pitch. Equipped with HD coating and IP67 protection for front optical element, it achieves high transmittance across 8‑12μm working waveband. The compact M17×0.5 mount supports focusing range from 3 meters to infinity. It maintains stable optical output within temperature span of ‑40℃ to +80℃ and brings high relative illumination alongside controlled distortion. It suits all‑weather field deployment and serves as ideal optical core for compact portable thermal camera devices covering industrial monitoring as well as security inspection scenarios.

The ultra wide angle lens PL-WA2.44 is a premium M12 board lens manufactured by ShangHai SILK Optical Technology CO., LTD. This fixed focal lens adopts professional 5G+IR optical structure, precisely optimized for 1/2.9” image sensors to deliver outstanding panoramic capturing capacity. As a high-performance surveillance lens, it features 2.44mm effective focal length and F2.5 aperture, achieving an ultra-wide 162° diagonal field of view to eliminate monitoring blind zones. This miniature camera lens balances relative illumination and TV distortion to guarantee uniform, clear imaging across the whole image circle. ShangHai SLIK Optical Technology CO., LTD strictly controls optical tolerance and assembly precision for every embedded vision lens. Suitable for both daytime and infrared supplementary lighting scenarios, this reliable 1/2.9” camera lens is widely deployed in home security, intelligent equipment and machine vision projects. Clients can source stable, cost-effective ultra wide angle lens solutions directly from our factory.

BOSHI Optical Technology delivers a premium 1.5mm fisheye lens engineered for 1/4 inch AR0144 image sensors, offering outstanding ultra wide angle imaging capability for compact optical devices. This F2.2 M12 mount lens features a 200 degree diagonal field of view, capturing expansive scenes with minimal blind spots to meet the demand for full coverage monitoring and detection in limited installation space.With a total track length of 13.03mm and a standard M12 mount, this lens fits seamlessly into most board level camera designs, making installation and integration simple for various device manufacturers. The maximum image circle of 4.4mm fully covers the sensing area of 1/4 inch sensors, ensuring no obvious vignetting on the active imaging region. Its chief ray angle stays below 18 degrees, which matches well with the sensor microlens array and reduces image shading at the frame edges.This 1.5mm fisheye lens maintains 65 percent relative illumination, delivering more uniform brightness across the whole image plane for clearer detail recognition in both center and corner areas. Produced with strict quality control by BOSHI Optical Technology, this reliable M12 mount lens serves as an ideal optical solution for security, automotive and consumer electronics products that require broad field of view and stable long term optical performance.
