4.0mm 1/2.7" M12 Lens PL057, 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.

Developed and manufactured by BOSHI Optical Technology, this high‑performance 35mm thermal imaging lens targets long wave infrared thermal imaging devices operating within 8‑12μm spectral band. The thermal imaging lens adopts F1.0 large aperture design to achieve outstanding light gathering capacity, which can generate clear thermal imaging output under low‑light and complex ambient conditions. It provides full compatibility with 640×512 12μm uncooled infrared detectors. Its focus range covers 2m to infinity to support near‑distance observation and long‑range monitoring. The front element achieves IP67 ingress protection rating to sustain stable operation in tough outdoor conditions. With transmittance maintained above 92 percent and low distortion feature, this optical component delivers consistent image quality for industrial monitoring and perimeter security thermal vision systems.

This compact wide angle lens is manufactured by ShangHai SILK Optical Technology CO., LTD, tailored for 1/2.7‑inch image sensors for industrial and surveillance imaging tasks. As a high‑performance optical lens, it delivers a large diagonal field‑of‑view of 124°, bringing broad scene coverage for real‑time image capture. Featuring fixed focal design and M12 mount, this industrial camera lens owns compact overall dimension with total track length only 10.9mm, easy for embedding into small‑size imaging devices. Its F3.5 aperture balances light intake and optical performance, while controlled CRA value ensures good compatibility with mainstream CMOS sensors. ShangHai SILK Optical Technology CO., LTD strictly controls every production procedure, making this cctv lens stable for long‑time continuous operation. It strikes a fine balance between wide‑angle coverage and practical imaging quality, suitable for various space‑limited vision equipment, and offers reliable optical solution for different civilian and industrial visual‑recording scenarios.

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.
