2.9mm M12 IR Corrected Lens Applications

Core Application Scenes

This M12 IR corrected lens is designed for imaging systems that may operate under both visible light and near-infrared illumination. Unlike a conventional visible-light-only lens, an IR corrected optical design is intended to reduce focus shifts between different wavelength ranges, helping maintain usable image sharpness when the illumination spectrum changes.

The 2.9mm focal length provides a 97° diagonal field of view on a 1/2.7″ sensor, allowing the camera to cover a relatively broad area from a compact installation position. The F2.1 aperture also provides a practical balance between light collection and compact optical design.

With a fixed iris and M12x0.5 mount, the lens is well suited to camera modules that require a fixed optical configuration. Its 0.3m minimum object distance makes it more appropriate for medium-distance monitoring, sensing, and inspection than for extremely close-range imaging.

The lens is specified without an IRCF, which is relevant for systems that need the optical path to accommodate infrared wavelengths. The exact usable wavelength range and final image quality should be evaluated together with the camera sensor and IR illumination source.

Designed for visible and near-infrared imaging applications where stable focus across wavelengths is required.

Frequently Asked Questions

Q: What does IR corrected mean for this M12 lens?
A: IR‑corrected optics suppress focus shift between visible and near‑infrared wavelengths, ideal for cameras switching between visible‑light and IR illumination.

Q: Does this lens include an IR cut filter?
A: No. The specification states that the lens is supplied without an IRCF. This allows the optical system to accommodate infrared wavelengths rather than blocking them with an IR-cut filter.

Q: What is the field of view of the 2.9mm lens?
A: On a 1/2.7″ sensor, the specified field of view is 97° diagonal, 84° horizontal, and 68° vertical.

Q: Is this lens a low distortion lens?
A: No. The specified distortion is less than -6%, so it should not be positioned as a low distortion lens. Its primary optical advantages are wide-angle coverage and IR correction.

Q: Is the 2.9mm lens a fisheye lens?
A: No. Although it has a relatively wide 97° diagonal FOV, the available specification does not indicate a fisheye optical design. It is better described as a conventional wide-angle M12 lens.

Q: What sensor size is compatible with this lens?
A: This lens targets the 1/2.7″ image‑format sensor and delivers its stated FOV for this sensor size.

Q: What is the minimum object distance?
A: The M.O.D. is 0.3 m, suited for applications with moderate working distances between camera and target.

Q: What applications are suitable for this IR corrected lens?
A: Typical applications cover day‑night cameras, IR‑aided smart security, embedded vision, infrared inspection and machine‑vision sensing for camera systems working over visible and near‑infrared wavelengths.
