3.1mm M12 Low Distortion Wide Angle Lens Applications

Core Application Scenes

This 3.1mm M12 low distortion lens is developed for compact imaging systems that need high resolution and wide scene coverage without the strong geometric deformation associated with fisheye optics. Its 12.5MP resolution and < -1% distortion make it particularly suitable for vision systems where image detail and spatial consistency are both important.

In robotics vision, the 88° horizontal FOV provides a broad perspective for observing work areas, objects, and nearby obstacles. The 3.1mm focal length can be useful when a compact robotic camera needs to cover a relatively large area without moving the camera farther away from the target.

For compact industrial vision systems, the lens can support inspection or monitoring tasks where camera installation space is limited. The 0.2m M.O.D. allows relatively close-range imaging, while the 12.5MP resolution provides additional image detail for object recognition, surface observation, and AI-based visual analysis.

The lens is also suitable for embedded cameras installed in equipment operating across changing ambient conditions. Its specified -20°C to +70°C working temperature range makes it appropriate for industrial equipment, outdoor-capable embedded vision devices, and robotic platforms where operating temperature can vary during use.

Unlike an extreme wide-angle fisheye lens, this design combines a broad field of view with controlled distortion. This can reduce the amount of geometric correction required in applications that use image coordinates, object dimensions, or computer vision algorithms.

Designed for high-resolution compact machine vision, robotics perception, embedded AI imaging, and wide-area industrial imaging applications.

When selecting a lens for a 1/2.3″ camera, the Sensor Guide can help with sensor and image-format considerations. For broader optical matching requirements, refer to the Lens Selection Guide.

Because this lens combines a 102° FOV with distortion below -1%, engineers evaluating geometric accuracy can also review the Distortion Guide.

For systems where the required field of view or working distance is still being determined, the FOV Calculator can be used to estimate scene coverage.

Frequently Asked Questions

Q: What type of lens is the 3.1mm M12 lens?
A: This fixed‑focal low‑distortion wide‑angle M12 lens targets high‑resolution compact imaging systems, supporting 1/2.3″ sensor and 12.5‑MP resolution.

Q: What is the field of view of this 3.1mm lens?
A: With the 1/2.3″ sensor, the lens delivers 102° diagonal, 88° horizontal and 72° vertical FOV.

Q: Is this 102° lens a fisheye lens?
A: No. It delivers 102° diagonal wide‑angle FOV with distortion under ‑1%. Its well‑controlled distortion follows low‑distortion wide‑angle design principles, unlike fisheye lenses.

Q: What sensor size is this M12 lens designed for?
A: The lens is specified for a 1/2.3″ image format, with a maximum image circle of Φ8.3mm.

Q: What is the advantage of the 12.5MP resolution?
A: The 12.5MP resolution provides more image detail for applications such as object recognition, visual inspection, AI-based image analysis, and high-resolution scene monitoring.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, or 200mm. This supports relatively close-range imaging while maintaining a wide field of view.

Q: Can this lens be used for industrial machine vision?
A: Yes. Featuring high resolution, wide FOV, low distortion, M12 mount and‑20 °C ~ +70 °C operating temperature, it fits compact industrial and machine‑vision systems. Actual suitability relies on camera sensor, working distance, image coverage and inspection requirements.

Q: Does the IRCF specification mean the lens is IR corrected?
A: No. IRCF refers to an infrared-cut filter. It should not be interpreted as an IR-corrected optical design. IR correction and IR-cut filtering are different optical characteristics.
