Description
This 16mm low distortion M12 fixed focal machine vision lens is engineered for 1/3-inch 2MP CMOS sensors. Built with F1.8 large aperture and strictly controlled distortion below 0.5%, this industrial M12 board lens delivers sharp, edge-to-edge uniform images without geometric deformation. The compact Φ14×13.5mm housing fits tightly inside miniature camera modules, ideal for close-range fixed-point monitoring and machine vision detection. Our fixed iris design ensures stable light input in long-term continuous operation, solving blurry and distorted frame issues common with generic board lenses.
Key Product Highlights
- Field of View & Focal Length Advantage: 16mm prime focal length with 20° diagonal FOV, perfectly matches short-distance fixed-point shooting, no barrel distortion to interfere with measurement recognition.
- Ultra-Low Distortion Performance: Distortion <0.5%, far superior to ordinary CCTV lenses, keeps straight lines straight for machine vision inspection and text identification.
- Wide Aperture & Stable Imaging: F1.8 fixed aperture guarantees sufficient light intake at 0.3m minimum object distance, ensuring clear pictures under dim indoor lighting.
- M12 Compact Compatibility: Standard M12×0.5 thread mount and tiny body fit most miniature camera housings without structural modification.
- Long-Term Stable Quality: Fixed iris structure avoids aperture drift after long running hours, consistent image quality for 24/7 industrial operation.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
This low distortion M12 fixed focal lens is mainly deployed in industrial machine vision detection, small industrial barcode scanning cameras, desktop visual inspection modules, compact fixed-point industrial monitoring, small automated robot visual positioning, and mini IoT security cameras. It is specially designed for short-range shooting within 0.3m to several meters. The low-distortion optical design prevents geometric deviation during size measurement and character reading. The small outer size works well in narrow embedded installation spaces inside miniature camera modules, no need for extra machining on the device shell. It maintains stable imaging in indoor factory environments with fluctuating ambient light, effectively reducing recognition failure caused by distorted images.
Compatible Devices List
Compatible strictly with 1/3-inch 2MP CMOS image sensors. Perfectly adapted to miniature machine vision camera modules, embedded industrial vision boards, Tuya mini IoT cameras, small fixed CCTV monitoring cameras, automated equipment visual recognition modules, and desktop industrial inspection cameras. We accept customized optical parameters including focal length and distortion indicators to match customers’ proprietary camera hardware.
Designed for industrial machine vision application.
Frequently Asked Questions
Q: Does this lens work with 1/2.5-inch sensors?
A: It is optimized exclusively for 1/3-inch sensors; using a smaller sensor will narrow the field of view without optical vignetting.
Q: Can I adjust the aperture manually?
A: This model uses a fixed iris; variable aperture versions can be customized upon request.
Q: What is the closest focusing distance?
A: The minimum object distance is 0.3 meters, ideal for close-range industrial inspection tasks.
Q: Is this lens suitable for outdoor 24-hour monitoring?
A: It works for indoor and sheltered outdoor environments; IR corrected coating can be added for night vision needs.
Q: Can you provide third-party optical test reports?
A: Yes, we support third-party distortion and resolution testing with formal certification documents.
