Description
This 1/2.3 inch 3mm M12 wide angle fixed focal lens is a 5MP high-definition industrial & CCTV optical lens optimized for miniature smart imaging devices. Featuring a super wide 104° field of view, ultra-low distortion below 1%, and professional IRCF infrared correction structure, this fixed iris lens delivers consistent clear imaging day and night. With a compact 20.9mm TTL design and 0.01m ultra-short minimum focusing distance, it perfectly fits space-limited smart security, home monitoring and micro machine vision equipment. As a high-performance low distortion wide angle M12 lens, it effectively solves edge distortion and narrow viewing angle issues of ordinary surveillance lenses.
Core Product Highlights
Super Wide Field of View Covers More Monitoring Area
104° diagonal wide FOV greatly expands monitoring coverage, eliminating blind spots for small cameras; ideal for compact devices that cannot install multiple lenses.
Ultra-Low Distortion Restores Real Scene Imaging
Strictly controlled distortion below -1%, far better than ordinary wide-angle lenses, avoids image stretching and edge warping for accurate video recording and vision recognition.
5MP HD &IRCF
Built-in IRCF infrared filter structure ensures synchronous clear imaging in daytime visible light and nighttime infrared environment, no blurry night vision.
Universal M12 Mount & High Device Compatibility
Standard M12x0.5 thread mount features plug-and-play installation, no modification needed, compatible with most mainstream miniature camera modules.
Industrial-Grade Stable Optical Quality
3G2P professional optical lens structure + fixed F4.0 aperture ensures stable light intake and long-term continuous operation without image quality decay.
