Our 1/9 Inch 140 degrees Wide Angle Endoscope Lens, Waterproof， The endoscopic lens plays an important auxiliary role in medical inspection. The purpose of the endoscopic lens is to guide the image, which transmits the image reflecting the endoscopic situation of the organ. The monitor is convenient for the doctor to observe the details of the tissue in the cavity clearly, and provides help for the doctor's safe operation and fine operation.

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.

The 4.1mm F1.0 thermal lens adopts advanced exposed AR anti-reflection coating, achieving over 88% infrared transmittance. As a professional optical product from manufacturer ShangHai SLIK Optical Technology CO., LTD, this M22×0.5 mount thermal lens features IP67 front lens protection, lightweight ~25g structure and robust wide-temperature optical stability, perfectly tailored for compact uncooled thermal camera system integration.

Standard M12 F1.6 3.0mm 1/2.7" Vehicle Dashcam Lens with IR-cut, 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 delivers a premium 1.5mm fisheye lens engineered for 1/4 inch AR0144 image sensors, offering outstanding ultra wide angle imaging capability for compact optical devices. This F2.2 M12 mount lens features a 200 degree diagonal field of view, capturing expansive scenes with minimal blind spots to meet the demand for full coverage monitoring and detection in limited installation space.With a total track length of 13.03mm and a standard M12 mount, this lens fits seamlessly into most board level camera designs, making installation and integration simple for various device manufacturers. The maximum image circle of 4.4mm fully covers the sensing area of 1/4 inch sensors, ensuring no obvious vignetting on the active imaging region. Its chief ray angle stays below 18 degrees, which matches well with the sensor microlens array and reduces image shading at the frame edges.This 1.5mm fisheye lens maintains 65 percent relative illumination, delivering more uniform brightness across the whole image plane for clearer detail recognition in both center and corner areas. Produced with strict quality control by BOSHI Optical Technology, this reliable M12 mount lens serves as an ideal optical solution for security, automotive and consumer electronics products that require broad field of view and stable long term optical performance.

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.
