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.

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.

This high-performance M12 fisheye lens is engineered by ShangHai SILK Optical Technology CO., LTD to deliver seamless panoramic monitoring with an ultra wide angle field of view. Designed for 1/2.7” image sensors, this ultra wide angle lens adopts a mature 2G3P+IR optical structure, balancing compact size and all-day imaging capacity. It features a 2.18mm effective focal length, F2.4 fixed aperture and 185° diagonal field of view, enabling single-camera wide-area coverage without stitching multiple cameras. As a reliable IR corrected lens, it maintains consistent image quality under visible and infrared light for day-night surveillance scenarios. The total track length is controlled at 14.5±0.2mm, supporting miniaturized camera module integration. Strict optical calibration delivers 46.0% relative illumination and controlled CRA under 20.43°, greatly reducing vignetting and matching mainstream CMOS sensors. ShangHai SLIK Optical Technology CO., LTD provides stable mass production and customizable optical solutions for global clients using this mature panoramic lens platform.

F1.6 4.0mm 1/2.7" M12 FPV Drone 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.

Our Full Color F1.0 blacklight M12 lens 4mm demonstrates significant advantages in stray light suppression, edge imaging sharpness and light transmittance, with higher yield and better consistency. It can still clearly capture details in low-light conditions.

This F1.0 19mm Infrared Thermal Lens developed by BOSHI Optical Technology is a high‑performance optical component tailored for long‑wave infrared thermal imaging systems that operate within the 8‑12μm wavelength band. This 19mm Infrared Lens supports 640×512,12μm infrared detectors, and strikes a fine balance between moderate horizontal field of view and remarkable light gathering capability. Manufactured by BOSHI Optical Technology, this Long Wave Infrared Lens applies AR Coating over all exposed optical surfaces and delivers IP67 front‑element waterproof construction to cope with complicated outdoor harsh conditions. It features adjustable focus covering 0.5 metre to infinity and maintains steady optical performance across ‑40℃ to +80℃, bringing satisfactory transmittance and relative illumination output. It acts as dependable optical hardware for industrial monitoring, perimeter security as well as temperature measurement thermal cameras.
