Description
This 3.1mm M12 fixed focal low-distortion lens is engineered for 1/4” 2MP image sensors. Adopting 5P+IR infrared corrected optical structure, the lens delivers sharp, uniform imaging across visible and infrared spectrum. Compact dimension and fixed F2.4 aperture make it an ideal optical component for compact IoT cameras, mini surveillance modules and miniature machine vision equipment.
Core Product Highlights
- Wide 65° diagonal field of view, covers larger monitoring area without blind zones (solves narrow view limitations of short focal competitors)
- Ultra-low distortion below -1.5%, minimizes image bending for accurate visual recognition and surveillance recording
- IR corrected 5P optical design, ensures consistent clarity day and night under infrared supplementary lighting
- Standard M12×0.5 mount with ultra-small Φ14×12.19mm size, easy installation for space-limited device housing
- F2.4 fixed aperture, stable light intake, perfectly matched with mainstream 2MP 1/4-inch CMOS sensors

Application Scenarios & Compatible Devices
This M12 wide-angle low distortion lens is widely deployed in smart home surveillance systems, mini IP cameras, intelligent video doorbells, small access control cameras, miniature industrial visual detection modules, consumer IoT cameras and compact machine vision equipment. Thanks to its ultra-small outline and low-distortion optical performance, it works steadily in indoor monitoring, unattended access identification and miniature visual detection environments. The IR-corrected structure maintains clear imaging under IR night vision, removing color shift common in ordinary CCTV lenses.
Compatible device list: Fits all cameras equipped with M12×0.5 lens holder, matched with 1/4 inch 2MP CMOS image sensors. Compatible with generic IoT camera modules, smart video doorbell modules, miniature machine vision acquisition units and low-power security camera boards. Custom optical tuning and bulk OEM services are available for mass orders.
Designed for compact CCTV, smart IoT and miniature machine vision application.
Frequently Asked Questions
Q1: Which sensor size does this 3.1mm lens support?
A1: Optimized for 1/4” 2MP image sensors. It is not recommended to use on sensors larger than 1/4 inch to avoid vignetting.
Q2: Is this lens IR compatible for night vision cameras?
A2: Yes. The 5P+IR optical structure provides IR correction, suitable for cameras with infrared LED illumination for day-night surveillance.
Q3: What is the distortion level of this M12 lens?
A3: Distortion is controlled below -1.5%, classified as low distortion lens, suitable for scenarios requiring straight-edge image output.
Q4: Can I adjust the aperture of this lens?
A4: This is fixed iris lens. The aperture is F2.4 and cannot be manually adjusted.
Q5: Does this lens fit C-mount or CS-mount cameras?
A5: No. It adopts standard M12×0.5 mount, only compatible with M12 lens holders.
Q6: Can you provide sample testing before bulk purchase?
A6: Yes, lens samples are available for customer performance testing. Contact our sales team for sample quotation.
Q7: Is the product RoHS compliant for EU export?
A7: All lenses pass RoHS certification and follow ISO9001 production standards to meet European market access requirements.
