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.

4.1mm F1.0 M22 12um HD Lens Long-wave Infrared Thermal Imaging Lens is high-performance, rugged, and highly compact infrared lens engineered for premium commercial and industrial applications. Striking an exceptional balance between physical size, weight, and premium optical performance (large aperture, wide FOV), it stands out as a premier choice for drones, automotive night vision, and harsh-environment security applications.

Standard M12 2.8mm 1/2.7" F2.4 3MP 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.

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.

BOSHI Optical Technology presents the PL-02934H-M12, a high performance 2.9mm Cone Lens — a wide angle fixed lens for 1/4" Image Sensor formats. With 2.9mm Focal Length and F3.4 Aperture, this Wide Angle Optical Lens delivers a 119° Field of View for broad scene coverage in tight spaces. The all glass construction supports thermal stability and consistent image quality. A controlled Chief Ray Angle below 6.63° reduces colour shading with modern CMOS sensors. The Compact Fixed Lens has an 8.9mm total track length and a 2.46mm mechanical back focal distance for M12 Lens Mount integration. BOSHI Optical Technology balances TV Distortion at about 14.27% barrel distortion, a typical value for wide angle optics that digital correction can address. Relative illumination is 30% at the edge for usable brightness in low light. This lens suits Surveillance and Automotive Imaging, embedded vision, security cameras, in vehicle surround view systems, and industrial inspection. The 2.9mm Focal Length and 119° Field of View support dashcams, doorbell cameras, and compact devices. The F3.4 Aperture provides useful depth of field from 0.3m to infinity.

F1.6 4.0mm 1/2.7" M12 Network Camera 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.
