This 3.1mm M12 fisheye lens is designed for applications requiring an extremely wide field of view in a compact optical package. With a 1/1.8″ image format, 6MP resolution, 170° diagonal FOV, F1.8 aperture, and 0.1m minimum object distance, it provides broad scene coverage for embedded vision, machine vision, monitoring, and other space-constrained imaging systems. The M12×0.5 mount makes it suitable for compact camera modules and custom vision assemblies.
For projects requiring different focal lengths or field-of-view configurations, explore our M12 Lenses or use the FOV Calculator to evaluate the required coverage before selecting an optical configuration.
The combination of a 3.1mm focal length and 170° diagonal field of view makes this lens fundamentally different from conventional wide-angle lenses. Its strong optical distortion is part of the ultra-wide-angle imaging design, making it appropriate where maximum scene coverage is more important than rectilinear image geometry. For applications where geometric accuracy is the priority, review our Distortion Guide before choosing between fisheye and low-distortion optical designs.
This 3.1mm 6MP fisheye lens is particularly suitable for vision systems that need to observe a large area from a short camera-to-subject distance. Its ultra-wide FOV can reduce the number of cameras required for certain coverage-oriented applications while maintaining 6MP image resolution.
Embedded Wide-Angle Vision
The compact M12×0.5 interface allows the lens to be integrated into small camera modules where installation space is limited. It can provide broad environmental visibility without requiring a long focal length lens assembly.
Machine Vision & Area Monitoring
For machine vision systems that need to observe a large working area rather than perform precision dimensional measurement, the 170° diagonal FOV can provide extensive scene coverage. The 0.1m MOD is also useful for close-range inspection and observation.
Robotics Vision
Robotic platforms can use ultra-wide-angle optics when broad environmental awareness is more important than narrow, high-magnification imaging. The compact M12 format is suitable for vision modules where weight and installation space need to be controlled.
Wide-Area Monitoring
The combination of 3.1mm focal length and 170° diagonal coverage can be used in monitoring devices requiring a large viewing area from a fixed camera position. The fisheye optical design is especially appropriate when edge-to-edge scene coverage is a priority.
Designed for ultra-wide-angle machine vision application, this lens is a practical option for systems that prioritize maximum visual coverage within a compact M12 optical assembly.
For camera and sensor matching, our Sensor Guide can help determine whether the 1/1.8″ image format is appropriate for your imaging system. You can also review the Lens Selection Guide when comparing focal length, sensor format, FOV, and mounting requirements.
Q: What type of lens is this 3.1mm M12 lens?
A: It is a 6MP M12 fisheye lens with an ultra-wide 170° diagonal field of view. Its optical design prioritizes maximum scene coverage rather than low geometric distortion.
Q: Is this lens suitable for machine vision?
A: Yes. Its 6MP resolution, M12 mount, 0.1m minimum object distance, and extremely wide FOV make it suitable for machine vision systems that require broad-area or close-range scene capture rather than precision measurement.
Q: Why does this lens have -78% optical distortion?
A: The high negative distortion is characteristic of its ultra-wide fisheye optical design. This allows the lens to achieve a very large 170° diagonal field of view while maintaining a compact focal length.
Q: Is this a low-distortion lens?
A: No. With optical distortion specified below -78%, this lens should be considered a fisheye or ultra-wide-angle design rather than a low-distortion lens. For applications requiring accurate geometric reproduction, a low-distortion optical configuration should be considered.
Q: What is the advantage of the 0.1m minimum object distance?
A: A 0.1m minimum object distance allows the lens to capture subjects at relatively short distances while maintaining its very wide viewing angle, making it useful for close-range environmental and area imaging.
Q: Can the M12 lens be customized for an OEM camera?
A: Yes. TOWIN can evaluate optical and mechanical requirements for OEM/ODM projects, including sensor format, focal length, FOV, mounting interface, and application-specific imaging requirements. Contact our Optical Design team or Contact TOWIN for project evaluation.
Q: How can I calculate the field of view before selecting this lens?
A: You can use the FOV Calculator to estimate image coverage based on sensor size, focal length, and working distance before confirming the optical configuration.
When selecting an ultra-wide-angle lens, focal length and sensor format should be evaluated together because the same focal length can produce different fields of view on different sensors. The 3.1mm design of this lens is optimized for extremely broad coverage, while its strong distortion should be considered according to the image-processing requirements of the application.
