4.4mm M12 IR Corrected Lens Applications

Core Application Scenes

This 4.4mm M12 IR corrected lens is specifically suited to imaging systems that operate across different lighting conditions or use near-infrared illumination. Its IR-corrected optical design helps reduce focus shifts between visible light and near-infrared wavelengths, making it useful for cameras that need to maintain consistent image clarity during day-and-night operation.

With a 90° horizontal FOV on a 1/1.8″ sensor, the lens can capture a broad scene from a relatively compact camera position. The F2.0 aperture further supports applications where available illumination may vary, making this lens suitable for smart security cameras, NIR imaging modules, embedded monitoring devices, biometric imaging equipment, and low-light vision systems.

The lens is also suitable for applications where a camera alternates between normal visible-light imaging and infrared illumination. In these systems, optical focus consistency is important because changes in wavelength can otherwise introduce focus differences that reduce image sharpness.

For embedded security and AI vision equipment, the compact M12×0.5 interface allows the lens to be integrated into small camera housings. The 12MP resolution provides sufficient image detail for recognition and monitoring tasks, while the wide FOV allows one camera to observe a relatively broad area.

Engineers evaluating sensor and lens compatibility can refer to Towin’s Sensor Guide and Lens Selection Guide when determining the appropriate sensor format and optical configuration.

Frequently Asked Questions

Q: What type of lens is this 4.4mm M12 lens?
A: It is a fixed focal, wide-angle M12 lens with an IR-corrected optical design. It supports 1/1.8″ and 1/2.3″ image formats and provides up to 12MP resolution.

Q: What does IR corrected mean for this lens?
A: IR‑corrected optics minimize wavelength‑induced focus shift, proving valuable for camera systems combining visible‑light imaging with NIR illumination.

Q: What is the FOV of the 4.4mm lens?
A: On a 1/1.8″ sensor, the lens provides 99° diagonal, 90° horizontal, and 55° vertical FOV. On a 1/2.3″ sensor, it provides 92° diagonal, 77° horizontal, and 60° vertical FOV.

Q: Is this a low distortion lens?
A: No. The supplied distortion specifications are below -14% for 1/1.8″ and below -10% for 1/2.3″. Therefore, it should not be categorized or marketed as a Low Distortion Lens.

Q: What sensor formats are supported?
A: The lens is specified for both 1/1.8″ and 1/2.3″ image formats. The resulting FOV and distortion vary according to the sensor format used.

Q: What applications are suitable for an IR corrected M12 lens?
A: Typical applications cover day‑night cameras, NIR imaging, smart security, biometric imaging, embedded AI cameras and low‑light vision systems needing stable focus across wavelengths.

Q: Why is the F2.0 aperture useful for this lens?
A: Its F2.0 aperture delivers a large optical opening, passing more light to the sensor versus smaller apertures. This benefits applications with limited or variable lighting conditions.

Q: How can I select the right sensor and field of view for this lens?
A: The appropriate configuration depends on the camera sensor, installation distance, target dimensions, and required coverage. Towin’s Lens Selection Guide and FOV Calculator can assist with the selection process.
