Description
This 3.5mm low distortion M12 fixed focal industrial machine vision lens is engineered for 1/4” 5MP image sensors. Featuring ultra-low distortion, wide 65° diagonal field of view and compact mini body, this wide angle M12 lens delivers sharp, uniform imaging across the whole sensor. Built with 2G2P optical structure and fixed F3.0 aperture, it supports close-range object capture starting from 0.1m MOD. Widely adopted in industrial visual inspection, intelligent IoT monitoring and miniature vision devices, this low distortion M12 lens balances imaging performance and space-saving installation requirements for small-sized camera modules.
Key Product Highlights
Wide Angle & Optimized FOV Matching
Offers 65°(D)/55°(H)/40°(V) field of view, perfectly matched for 1/4” sensors; captures broader scene information without blind zones compared to standard narrow-angle lenses.
Ultra-Low Distortion Optical Performance
Distortion controlled below -0.4%, effectively reduces image deformation. Solves distortion pain points for measurement, identification and visual detection scenarios.
Universal M12 Interface & Mini Compact Size
Standard M12×0.5 mount, Φ14×15.79mm tiny dimension. Fits miniature camera modules with limited internal installation space without structural modification.
5MP High Resolution Imaging Capability
2G2P optical configuration supports 5 megapixel sensor, presents clear edge details for close-range shooting with fixed F3.0 aperture.
Short Minimum Object Distance Design
MOD reaches 0.1m, realizes clear close-distance shooting, ideal for near-field industrial recognition and compact monitoring equipment.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
Primarily used in miniature industrial machine vision detection equipment, intelligent IoT mini cameras, smart access control visual modules, small logistics barcode recognition devices, robot auxiliary vision systems, miniature security monitoring cameras and biometric auxiliary shooting modules. Especially suitable for compact camera hardware with narrow internal assembly space, requiring wide-angle imaging and low distortion for data collection. The short 0.1m minimum focus distance enables stable clear imaging for close-range target identification, and the fixed aperture design reduces later maintenance costs for mass-produced camera modules.
Compatible Devices List
Compatible with all mainstream 1/4-inch CMOS sensors. Adapted to miniature IoT camera modules, industrial embedded vision boards, smart access control camera assemblies, low-power security camera modules and automated small inspection equipment. Customized optical parameters including focal length and field of view can be provided to satisfy different equipment iteration and adaptation demands for global device manufacturers.
Designed for industrial machine vision & miniature IoT camera application.
Frequently Asked Questions
Q: Can this M12 lens work with 1/2.8” or 1/3” image sensors?
A: This lens is optimized for 1/4” sensor. Using larger sensors will cause vignetting and incomplete image coverage, we recommend matching 1/4” sensors for best imaging effect.
Q: Is this lens IR corrected for infrared night vision?
A: Standard version has no special IR correction. Contact sales if you need IR corrected customized samples.
Q: Can I adjust the aperture of this 3.5mm lens?
A: This is fixed iris lens, aperture is fixed at F3.0 and cannot be manually adjusted.
Q: What does MOD 0.1m mean?
A: MOD stands for Minimum Object Distance. This lens can form clear images for objects starting from 0.1 meters away.
Q: How serious is the distortion of this lens?
A: Distortion is controlled below -0.4%, belonging to ultra-low distortion level, suitable for scenes requiring image authenticity.
Q: Does this lens support mass order and sample testing?
A: Yes, we provide free samples for testing, and support stable mass production supply.
Q: Is the lens RoHS compliant for European market export?
A: Yes, the lens is RoHS certified and meets EU environmental protection import requirements.
Q: Can you adjust the field of view or focal length on demand?
A: We accept optical customization for focal length, FOV and lens structure for bulk orders.
