China Infrared Thermal Imaging Lens Manufacturers, Suppliers, Factory

Our 1/9 Inch 140 degrees Wide Angle Endoscope Lens, Waterproof， The endoscopic lens plays an important auxiliary role in medical inspection. The purpose of the endoscopic lens is to guide the image, which transmits the image reflecting the endoscopic situation of the organ. The monitor is convenient for the doctor to observe the details of the tissue in the cavity clearly, and provides help for the doctor's safe operation and fine operation.

Manufactured by BOSHI Optical Technology, this highperformance ultra wide angle M12 mount lens is optimised for the 1/2.9 inch sensor, equipped with 1.8mm focal length and F2.0 aperture to realise extraordinary large scene capturing capacity. It provides 208 degree diagonal viewing range to realise complete panoramic imaging without visual dead zones. Compact mechanical size allows easy embedding into smallform camera modules. Every unit undergoes strict optical testing to realise steady high relative illumination and manageable ftheta distortion. BOSHI Optical Technology leverages mature optical manufacturing workflow to maintain reliable product consistency for mass order demands of panoramic monitoring and machine vision optics projects.

M12 2.85mm 1/2.9" F2.3 Security Lens PL071, and all products have been tested by MTF instruments, resulting in higher consistency compared to products from other suppliers. You can rest assured to purchase standard M12 lenses from our factory.

BOSHI Optical Technology presents the PL‑02934H‑M12, a high‑performance wide‑angle fixed lens engineered for 1/4" format sensors. 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.
