As a professional lens manufacturer, Boshi Lens (also named Silk Optical) operates strict quality management systems certified to ISO 9001:2000. 3.6mm 1/2.7" M12 Lens Glass plastic 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.

This high‑performance 75mm thermal imaging lens is independently developed and manufactured by BOSHI Optical Technology. This thermal imaging lens is optimised to pair with 640×512 thermal 17μm infrared detectors to realise high‑definition long‑wave infrared imaging output. It adopts large aperture F1.0 design. This optical athermalization lens delivers steady optical athermalization effect without additional electric focusing assemblies and maintains consistent imaging quality across extreme working temperature ranging from 40 degrees below zero up to 80 degrees centigrade. Equipped with high‑definition exposed‑optics coating, the lens achieves transmittance as high as 88 percent and relative illumination above 96 percent to realise even brightness distribution for full field of view. Its distortion value is controlled at 0.85 percent to reduce geometric deviation of captured images. It applies M34 mounting standard to support fast and stable assembly work. Front‑element IP67 rating offers outstanding dust‑proof and moisture‑proof performance. With net weight around 475 grams, this compact IR lens supports seamless integration for multiple infrared observation devices. Strict production quality control implemented by BOSHI Optical Technology makes this long wave infrared objective a reliable optical core component for outdoor thermal observation and monitoring work.

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.

In specific application scenarios, only dedicated barcode scanners can achieve accurate and efficient recognition. Design barcode Barcode scanner lens according to customer requirements, using optical plastic aspherical lenses, effectively reducing production costs while ensuring good performance.

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 3.0mm 1/2.7" M12 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.
