This compact M12 wide angle lens is professionally engineered for 1/3” image sensors, delivering ultra-wide diagonal 140° field of view for comprehensive scene capture. Manufactured by ShangHai SLIK Optical Technology CO., LTD, this fixed focal CCTV lens adopts mature optical layout to balance wide coverage and controllable TV distortion, making it a reliable IR corrected board lens for mass-market surveillance cameras. With F2.5 large aperture design, this low light camera lens supports clear imaging under dim indoor environments, while its 55.0% relative illumination effectively suppresses corner vignetting. Its CRA less than 22.8° guarantees excellent compatibility with mainstream CMOS sensors. The compact TTL 15.0mm structure simplifies camera module assembly. As a versatile industrial vision lens and security board lens, this wide FOV optical lens fits miniature IP cameras, home monitoring devices and embedded vision hardware. ShangHai SILK Optical Technology CO., LTD strictly controls optical tolerance to ensure consistent performance of every compact board camera lens for global buyers.

The M12 2.44mm Fisheye Lens (Model PL-WA02425C-M12) is a compact ultra-wide optic engineered for space-constrained digital cameras. Designed for 1/2.9-inch sensors, it delivers a 162° diagonal, 118° horizontal, and 89° vertical field of view. Featuring a robust 5G+IR optical stack, an F2.5 fixed aperture, and a standard M12 mount, it combines a 17.05mm total track length with a 6.3mm image circle. It provides an exceptional balance of broad coverage and natural color reproduction for dashcams, security, IoT devices, and machine vision.
