Description
This 50mm ultra-low distortion M12 fixed focal lens is engineered for high-precision industrial machine vision inspection. Built with strict optical polishing technology, it delivers sharp, distortion-free imaging across 1/2″ and 2/3″ image sensors. The fixed aperture and compact body maintain stable picture quality in long-term continuous operation, perfectly solving blurry images and geometric deviation problems that trouble ordinary industrial lenses. It is widely adopted in precision detection projects that demand high imaging consistency.
Key Product Highlights
Field of View/Focal Length Advantages
50mm long focal length brings narrow diagonal FOV at 9.2°, ideal for long-distance targeted shooting without picture cropping; calibrated FOV data matches 1/2″, 2/3″ and 1/3″ sensors to eliminate mismatched viewing angles.
Stable Optical Performance
Distortion strictly controlled below <-0.03%. F2.5 fixed aperture ensures uniform light intake. No focus shift occurs during long working hours to guarantee consistent measurement accuracy.
Excellent Hardware Compatibility
Standard M12x0.5 threaded mount. Fits 1/2″, 2/3″, 1/3″ image formats seamlessly. MOD reaches 0.4m to cover both close-range and medium-range detection tasks.
Strict Quality Assurance
Each lens undergoes full optical testing before delivery. Strict production flow avoids defective pieces, supporting third-party independent inspection for industrial procurement projects.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
This low-distortion M12 fixed focal lens is specially developed for precision machine vision measurement and industrial quality inspection tasks. It works steadily in factory workshops with moderate light changes, performing well in dimensional measurement of small electronic components, PCB circuit board defect detection, semiconductor chip appearance inspection, and positioning recognition for automated assembly lines. The ultra-low distortion effectively prevents measurement errors caused by image deformation during visual calculation. The long focal length supports medium-distance targeted shooting when the camera is installed far from detected workpieces, with no need for frequent lens replacement. It maintains stable imaging quality under 24-hour non-stop industrial operation and resists minor temperature fluctuations inside automated equipment.
Compatible Devices List
Compatible with 1/2″, 2/3″, 1/3-inch megapixel CMOS and CCD image sensors. It matches most industrial machine vision USB cameras, automated inspection camera modules, and small embedded vision cameras used in automated production lines. The standard M12 threaded port can be directly locked onto camera holders without modification. We also accept non-standard optical parameter customization to satisfy special visual inspection requirements from automated equipment manufacturers.
Designed for industrial machine vision application.
Frequently Asked Questions
Q: Can this M12 50mm lens be used for dimensional measurement?
A: Yes. With distortion below -0.03%, geometric deformation is negligible, which meets the precision requirement of industrial size measurement.
Q: Does this lens support 1/3-inch image sensors?
A: Absolutely. We have calibrated clear horizontal, vertical and diagonal field-of-view data for 1/3″ sensors for direct matching.
Q: Is the aperture adjustable?
A: No. This is a fixed iris lens with F2.5 fixed aperture to keep light intake consistent for stable long-term imaging.
Q: What is the shortest working distance?
A: The minimum object distance is 0.4 meters, which covers most close-range industrial detection work.
