7.9mm M12 Low Distortion Lens Applications

Core Application Scenes

This 7.9mm M12 low distortion lens is designed for high-resolution imaging applications where the camera needs to capture a defined target area with substantially more detail than a short-focal-length wide-angle lens. Its 44° horizontal FOV provides a relatively focused viewing area, making it suitable for cameras positioned at a moderate distance from the subject.

The combination of 12.3MP resolution and < -2.4% distortion makes this lens particularly suitable for applications where image detail and geometric consistency are both important. It can be used in high-resolution embedded vision cameras, robotic observation modules, smart monitoring equipment, compact inspection systems, and AI-enabled imaging devices.

The specified compatibility with the Sony IMX477 1/2.3″ sensor is another important advantage for camera developers. Instead of treating the lens as a generic M12 optic, engineers can evaluate it as part of a defined lens-and-sensor combination, helping simplify optical selection during camera module development.

The 0.5m minimum object distance makes the lens more appropriate for medium-range imaging than the close-focus M12 models in this series. It can therefore be positioned farther from the target while maintaining a controlled field of view, which is useful for equipment monitoring, robotic observation, and defined-area surveillance.

For engineers developing high-resolution camera modules, Towin’s Sensor Guide provides guidance on matching lens specifications with sensor formats. The Lens Selection Guide can also help evaluate focal length, working distance, FOV, and resolution requirements.

Frequently Asked Questions

Q: What type of lens is this 7.9mm M12 lens?
A: It is a fixed focal, low distortion M12 lens designed for 1/2.3″ image sensors and 12.3MP imaging. It features a 7.9mm focal length and < -2.4% distortion.

Q: Which sensor is this lens designed for?
A: The supplied specification identifies the Sony IMX477 as the reference sensor for the 1/2.3″ format. This provides a defined sensor platform for evaluating the lens-camera combination.

Q: What is the field of view of the 7.9mm lens?
A: On the specified 1/2.3″ IMX477 configuration, the lens provides a 54° diagonal FOV, 44° horizontal FOV, and 34° vertical FOV.

Q: Is this 7.9mm M12 lens a wide-angle lens?
A: No. Its 44° horizontal FOV and 34° vertical FOV provide a moderate, relatively focused viewing angle rather than the broad coverage associated with dedicated wide-angle lenses.

Q: What is the advantage of the 12.3MP resolution?
A: Its 12.3MP optical specification delivers rich image detail, benefiting visual inspection, detailed monitoring, robotics and computer‑vision applications that require fine feature retention.

Q: What does the < -2.4% distortion specification mean?
A: It indicates that the lens is designed to limit geometric deformation in the captured image. Controlled distortion can help maintain more consistent object shapes and spatial relationships across the image.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.5m. This makes the lens more suitable for applications where the camera is installed at a moderate distance from the target rather than directly adjacent to it.

Q: Does the IRCF specification mean that this is an IR corrected lens?
A: No. IRCF denotes an IR‑cut filter setup. By contrast, an IR‑corrected lens compensates focus shift between visible and NIR wavelengths, representing a distinct optical property.
