China F2.4 Manufacturers, Suppliers, Factory

As a professional lens manufacturer, this 1/2.7” 6.58mm Smart Home DV Lens and other Boshi Lens (also named Silk Optical) operates strict quality management systems certified to ISO 9001:2000. Our strengths include a powerful in-house R&D and engineering team, and a controlled manufacturing environment where all products are produced, assembled, and tested in dust-free cleanrooms.

Manufactured by BOSHI Optical Technology, this high‑performance ultra wide angle M12 mount 1.8mm Fisheye 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 small‑form camera modules. Every unit undergoes strict optical testing to realise steady high relative illumination and manageable f‑theta 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.

75mm F1.0 10MP M34 17um Lens Long-wave Infrared Thermal Imaging Lens is a high-end uncooled infrared thermal imaging telephoto lens with outstanding overall performance.

Standard M12 16mm 1/2.7" F2.0 5MP Security CCTV Lens, 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.

BOSHI Optical Technology designs and manufactures this high performance wide angle lens tailored for 1/2.7 sensor based imaging devices. As a 3.26mm fixed focal lens with a remarkable F1.0 large aperture, it excels at capturing clear and bright images even in dim ambient light, which greatly reduces motion blur and improves low light imaging quality for security and monitoring use. This M12 mount CCTV lens delivers a 129.5 degree diagonal field of view, enabling broad scene coverage with fewer blind spots for wide area surveillance. It comes with a built in 650nm IR cut filter to deliver accurate color rendering in visible light environments, ensuring true to life image output for daytime monitoring.With a compact total length of 22.5mm, the lens fits easily into various compact camera housings and supports flexible installation in space constrained scenarios. It maintains stable optical performance across an operating temperature range from -20℃ to 70℃, adapting to both indoor and harsh outdoor environments. BOSHI Optical Technology applies strict quality control over every production link to ensure consistent performance and long service life. This F1.0 large aperture lens is a cost effective solution for modern CCTV systems, indoor monitoring, and general industrial imaging projects that demand wide coverage and reliable low light performance.
