China F2.4 lens Manufacturers, Suppliers, Factory

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.

4mm Standard M12 Starlight lenses,and all of our lenses have been tested using the MTF instrument, and their consistency is superior to that of products from other suppliers. You can rest assured to purchase various standard M12 lenses from our factory.

This F1.0 25mm long wave infrared lens is developed and supplied by ShangHai SILK Optical Technology CO., LTD. As a high-performance thermal imaging lens working within 8~12μm wavelength range, this LWIR optics is optimized for 640×512, 12μm lens thermal detectors. Featuring a large aperture of F1.0, the infrared lens delivers outstanding light gathering capacity, making it ideal for low-visibility and low-temperature monitoring scenarios. The M22×0.5 mount ensures convenient assembly onto matched thermal camera hardware. With front element IP67 ingress protection rating, the thermal camera lens supports reliable outdoor deployment. This 25mm F1.0 lens maintains high transmittance above 86% and relative illumination over 97%, together with distortion controlled below 2%. It supports focus adjustment from 2 meters to infinity, and operates steadily between -40℃ and +80℃. ShangHai SLIK Optical Technology CO., LTD strictly calibrates every infrared lens to guarantee consistent imaging quality for industrial, security and surveillance thermal devices.
