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.

BOSHI Slik Camera Polarizer Lens, UV lenses can filter out ultraviolet rays from sunlight, so they are also known as ultraviolet filters. Due to the fact that UV mirrors not only improve imaging, but also protect the lens from contamination such as dust and fingerprints. So. UV lenses are always installed in front of the lens without removing them, making them the most widely used color filters. The Camera Polarizer Lens (UV Filter), a core optical accessory manufactured and supplied by Jiangxi Boshi Intelligence Technology Co., Ltd. (BOSHI), a professional Chinese optical manufacturer with nearly 20 years of industry experience, owning standardized production bases in Jiangxi Province and Shanghai City. Available in a full range of mainstream specifications including 49mm, 52mm, 58mm, 62mm, 67mm, 72mm, 82mm and 86mm, this UV filter is the most widely used optical filter for cameras, with dual core values of imaging optimization and lens physical protection. Its primary optical function is to absorb ultraviolet rays with wavelengths below 400 nanometers and partial blue-violet light, eliminating the blue-purple color cast in images captured in foggy weather or high-altitude environments, reducing ultraviolet interference on camera CCD sensors, and effectively improving image clarity and color restoration performance. Meanwhile, it acts as a durable protective layer for camera lenses, blocking dust, fingerprints and other contaminants, and can be stably mounted on the front of the lens for long-term use. The document also specifies key usage notes: the filter should be removed during backlit or night shooting to avoid aggravated glare, and taken off when using other filters such as CPL to reduce vignetting risk and ensure optimal imaging quality. Backed by a strict ISO9001:2000 quality management system covering full production processes, the company provides wholesale and customized services, accepting OEM and ODM orders including personalized logo and packaging customization for global clients.
