3.2mm F2.0 Ultra Low Distortion M12 Lens 4G2P+IR IP69 Waterproof 93 Deg FOV for

OKS-3651-A4-650 is a high-performance ultra-low distortion M12 fixed lens designed for automotive monitoring, outdoor security and industrial vision equipment. It adopts 4G2P+IR optical configuration with multi-layer AR coating to enhance light transmittance, matched with 650nm infrared cut filter to restore true color in daytime. With 3.2mm focal length and F2.0 large aperture, it achieves 93° diagonal field of view for 1/3" sensor, and the distortion is controlled at only -0.5%, which greatly reduces image deformation and improves the recognition accuracy of machine vision and ADAS algorithms. IP69 high waterproof barrel can withstand high-pressure flushing, paired with -40℃~+85℃ wide temperature structure, supporting 24/7 all-weather operation on vehicle exterior, factory workshop and outdoor monitoring sites. Standard M12 thread mount for simple assembly of various camera modules.
