ShangHai SILK Optical Technology CO., LTD offers the M7 lens, a compact optical lens engineered for small format camera lens integration with 1/2.7" image sensors. This 6.2mm fixed focal lens adopts 4-group lens assembly design, delivering balanced imaging performance for miniature camera hardware. Boasting a maximum image circle of Ø7.0mm, this wide angle miniature lens supports diagonal 74° field‑of‑view to capture sufficient scene coverage. As a low CRA lens with chief ray angle below 15°, it perfectly matches common CMOS sensors and reduces vignetting risk, paired with 58.0% high relative illumination to maintain uniform brightness across the whole frame. Built with M7 compact mount, this surveillance optical lens features short total track length at 13.42±0.3mm, well‑suited for space‑constrained device housing. Manufactured by ShangHai SILK Optical Technology CO., LTD, this compact optical lens undergoes strict optical testing to guarantee consistent output for mass‑produced embedded vision devices.

With a 2.9mm focal length and a fast F3.4 aperture, this lens delivers a generous 119° diagonal field of view, making it ideal for applications that require broad scene coverage in tight spaces. Its all‑glass construction (3 elements) ensures thermal stability and consistent image quality across a wide temperature range. The lens features a controlled chief ray angle of less than 6.63°, which minimises colour shading and maintains colour accuracy when paired with modern CMOS sensors. Despite its compact 8.9mm total track length, the mechanical back focal distance of 2.46mm offers flexible integration with standard M12 mounts. BOSHI Optical Technology has carefully balanced the optical design to achieve a TV distortion of ‑14.27% – a typical value for ultra‑wide lenses that can be digitally corrected – and a relative illumination of 30% at the edge, ensuring usable brightness even in low‑light conditions. This lens is a cost‑effective solution for embedded vision, security cameras, in‑vehicle surround‑view systems, and industrial inspection where a 2.9mm focal length and wide 119° coverage are essential. Whether you are designing a dashcam or a doorbell camera, the PL‑02934H‑M12 offers the optical performance and mechanical robustness that BOSHI Optical Technology is known for, with full compatibility with 1/4" sensors and M12 interfaces.
