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.
