2.5mm M12 Wide Angle Lens Applications

Core Application Scenes

This 2.5mm M12 wide angle lens is designed for compact imaging systems that need broad scene coverage without the strong geometric distortion associated with fisheye optics. On a 1/2.7″ sensor, its 105° diagonal and 96° horizontal FOV allow a single camera to observe a relatively large area while maintaining less than 1% specified distortion.

A key feature of this lens is its Visible and 850nm Dual Pass Filter. Rather than being limited to visible-light imaging, the optical design supports transmission in the visible range and around 850nm, making it suitable for vision systems that combine conventional image capture with near-infrared illumination or sensing.

For smart security and intelligent monitoring devices, the 850nm capability can be useful when paired with an appropriate 850nm illumination source. The wide FOV helps cover larger areas from a fixed camera position, while the low-distortion design provides more controlled image geometry for downstream computer vision and image-analysis algorithms.

The compact M12x0.5 mounting format and 15.18mm TTL also make the lens suitable for embedded vision devices where installation space is limited. It can be integrated into compact sensing modules, edge-AI cameras, robotic perception systems, and specialized monitoring equipment.

Designed for compact dual-band vision, near-infrared-assisted imaging, smart monitoring, and embedded visual sensing applications.

When matching this lens with a camera sensor, the Sensor Guide can help verify sensor format and image-circle compatibility. For broader lens selection criteria, refer to the Lens Selection Guide.

For applications where visible and near-infrared imaging are both required, optical transmission and filter characteristics should be considered together with the camera sensor and illumination source.

The required viewing angle can be evaluated using the FOV Calculator, while the Focal Length Calculator can help determine focal length requirements based on sensor size, working distance, and target coverage.

Frequently Asked Questions

Q: What type of lens is this 2.5mm M12 lens?
A: It is a fixed focal, wide-angle, low-distortion M12 lens with a 2.5mm focal length, F2.2 fixed aperture, and M12x0.5 mount.

Q: What is the field of view of this lens?
A: On a 1/2.7″ sensor, the lens provides 105° diagonal, 96° horizontal, and 64° vertical FOV. On a 1/2.9″ sensor, the FOV is 97° diagonal, 90° horizontal, and 59° vertical.

Q: What is the distortion specification?
A: The specified distortion is less than -1%. This controlled distortion makes the lens suitable for wide-angle applications where excessive geometric deformation is undesirable.

Q: Does this lens support 850nm near-infrared imaging?
A: Yes. The optical construction includes an 850nm IR design with a Visible and 850nm Dual Pass Filter, allowing the lens to support visible-light and 850nm near-infrared transmission.

Q: Is this a fisheye lens?
A: No. Although the lens provides a 105° diagonal FOV on a 1/2.7″ sensor, its specified distortion is less than -1%. It is better categorized as a wide-angle low-distortion lens rather than a fisheye lens.

Q: What sensor sizes can this lens support?
A: The lens provides specified FOV values for 1/2.7″ and 1/2.9″ sensors, with a maximum image circle specification of Φ6.9mm. Actual compatibility should be confirmed against the camera sensor’s active imaging area.

Q: What applications can benefit from the 850nm dual-pass design?
A: Applications can include smart monitoring, embedded vision, near-infrared-assisted imaging, edge-AI cameras, and specialized sensing systems that use 850nm illumination together with visible-light imaging.

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