2.5mm M12 Low Distortion Lens Applications

Core Application Scenes

This 2.5mm M12 low distortion lens is designed for compact cameras that need a relatively broad viewing area while maintaining controlled image geometry. With an 89° diagonal FOV and 68° horizontal FOV on the OV5640 configuration, it can capture a substantial scene without relying on a fisheye optical design.

The <0.2% TV distortion specification is particularly valuable when objects near the edges of the image need to maintain a relatively accurate geometric appearance. This makes the lens suitable for compact inspection cameras, embedded vision modules, intelligent monitoring equipment, and visual sensing devices where excessive barrel distortion could reduce the usefulness of captured images.

Its 10.4mm T.T.L. and 2.65mm B.F.L. also make this lens appropriate for applications where optical space is limited. The compact M12 × 0.5 mounting interface allows it to be integrated into small camera housings and embedded imaging assemblies.

Designed for compact low-distortion wide-angle imaging and embedded machine vision applications.

Optical Performance & Design Considerations

The optical configuration combines a 2.5mm focal length with a 1/4″ image format, producing an 89° diagonal, 68° horizontal, and 53° vertical FOV with the OV5640 sensor. This provides broad scene coverage while maintaining a substantially more controlled distortion profile than typical ultra-wide or fisheye optics.

The specified TV distortion is below 0.2%, making this lens particularly relevant to applications where image geometry matters. For inspection, visual measurement, positioning, or image-analysis systems, controlling distortion can help maintain a more consistent relationship between the captured image and the physical scene.

The lens also provides 5MP resolution, making it suitable for compact camera modules where higher image detail is required. The F2.4 fixed aperture provides a consistent optical configuration, while the integrated IRCF is useful for standard visible-light camera systems that require IR-cut filtering.

For a detailed explanation of distortion and its effect on industrial imaging, engineers can review the Distortion Guide.

The 10.4mm T.T.L. and 2.65mm B.F.L. should also be considered during mechanical integration. For applications requiring alternative compact optical configurations, the M12 Lenses range provides additional options.
