Low Distortion Lens – CCL14031MPF

CCL14031MPF Low distortion wide angle 3.1mm 50° M12 mount lens HD MP for PC web camera

1/4″ 2MP 3.1mm M12 Wide Angle Low Distortion Lens

This 1/4″ 2MP M12 lens features a 3.1mm fixed focal length, 65° diagonal field of view, and less than 1.5% distortion for compact wide-angle imaging systems. Its F2.4 fixed aperture provides a practical optical configuration for embedded cameras and monitoring modules, while the Φ14 × 12.19mm compact design helps reduce the space required for camera integration.

Designed as a compact M12 wide angle lens, this model combines a 1/4″ image format with 2MP resolution and a short 3.1mm focal length. The M12x0.5 mount makes it suitable for compact camera architectures where simple mechanical integration, controlled distortion, and moderate scene coverage are important. For additional M12 options, see the TOWIN M12 Lenses portfolio.

Low Distortion Lens Applications

Compact Security Camera

The combination of a 3.1mm focal length and 65° diagonal FOV makes this lens suitable for compact monitoring cameras that need moderate scene coverage without an extremely wide-angle perspective. Its controlled distortion can help maintain a more natural representation of objects within the captured image.

For applications requiring different levels of scene coverage, TOWIN also provides a dedicated Wide Angle Lens range.

Embedded Vision and IoT Cameras

The Φ14 × 12.19mm optical package is particularly useful when the camera enclosure has limited internal space. The short overall optical design allows system engineers to integrate the lens into compact electronic equipment without requiring a large lens barrel.

Access Control and Entrance Monitoring

For systems where image geometry is an important selection factor, the lens can be compared with other TOWIN Low Distortion Lens solutions. Engineers can also refer to the Distortion Guide when evaluating the effect of lens distortion on the final image.

Compact Imaging Devices

The fixed F2.4 aperture and fixed iris provide a straightforward optical configuration for products designed around stable lighting conditions. The 1/4″ format and 2MP resolution are appropriate for compact camera systems where extremely high megapixel performance is not the primary requirement.

Before selecting the lens, engineers should verify the sensor format, active sensor dimensions, and mechanical compatibility. TOWIN’s Sensor Guide can be used as a reference when matching an image sensor with an M12 lens.

For a more precise field-of-view evaluation, the FOV Calculator can help estimate the relationship between sensor size, focal length, and viewing coverage.

Frequently Asked Questions

Q: What type of lens is this?
A: This is a 1/4″ 2MP fixed focal M12 lens with a 3.1mm focal length, 65° diagonal FOV, and less than 1.5% specified distortion.

Q: What is the field of view of this 3.1mm M12 lens?
A: The lens provides a 65° diagonal FOV, 50° horizontal FOV, and 37° vertical FOV on the specified 1/4″ image format.

Q: Is this considered a low distortion lens?
A: Yes. The specified distortion is below -1.5%, providing controlled geometric distortion for compact imaging applications where image shape and scene representation matter.

Q: Is this an IR corrected lens?
A: The specification lists a 5P + IR optical configuration, but this alone does not establish IR correction. IR correction generally refers to maintaining focus consistency across visible and infrared wavelengths, so the specific optical performance should be confirmed for an IR imaging application.

Q: What sensor size is this lens designed for?
A: The lens is specified for a 1/4″ image format. The actual camera design should also verify the sensor’s active dimensions and optical compatibility before integration.

Q: What applications are suitable for this 2MP M12 lens?
A: It is suitable for compact security cameras, embedded monitoring modules, access-control cameras, IoT imaging devices, equipment monitoring systems, and other small camera modules requiring moderate wide-angle coverage.

Q: What is the back focal length of this lens?
A: The specified B.F.L. is 1.78mm. Mechanical and sensor positioning should be verified during camera integration.

Q: Can TOWIN provide customized M12 lens solutions?
A: TOWIN can evaluate optical and mechanical requirements based on the target sensor, focal length, FOV, distortion, resolution, mounting configuration, and camera enclosure. For project-specific requirements, contact TOWIN.
