Low Distortion Lens – CCL122914MP

CCL122914MP is 29mm Telephoto low-distortion lens, 1/2″ IR corrected Megapixel CCTV lens, F1.4 M12/S-mount lens, Low Light Sensitive Lens.

For engineers comparing compact optical solutions with different distortion and focal-length characteristics, Towin’s M12 Lenses category provides additional M12 configurations.

1/2″ 29mm M12 Low Distortion IR Corrected Fixed Focal Lens

This 1/2″ 29mm M12 low distortion fixed focal lens combines a narrow 12° horizontal field of view with an exceptionally low -0.2% distortion specification. With an F1.4 aperture, M12x0.5 mount, and IR-corrected optical design, it is well suited to compact imaging systems that require stable target framing and accurate image geometry.

M12 Low Distortion Lens Core Highlights

• -0.2% low distortion helps preserve image geometry and straight-line accuracy.
• 29mm fixed focal length provides focused imaging with a 12° horizontal FOV.
• F1.4 aperture supports strong light collection for demanding illumination conditions.
• IR corrected optics support visible and near-infrared imaging applications.
• Compact M12x0.5 design simplifies integration into space-constrained camera systems.

M12 Low Distortion Lens Applications

Core Application Scenes

This 29mm M12 low distortion lens is designed for imaging systems where the camera needs to concentrate on a defined target while maintaining accurate image geometry. Its 12° horizontal field of view provides a focused perspective, making it suitable for monitoring specific objects, equipment areas, access points, or other controlled regions rather than large panoramic scenes.

The key advantage of this optical configuration is its -0.2% distortion. Compared with conventional wide-angle optics that can introduce substantial barrel distortion, this lens is designed to maintain much straighter image geometry. This characteristic can be valuable when the visual shape and relative position of objects need to remain consistent across the image.

The 29mm focal length also provides a narrower viewing angle than shorter M12 lenses, making it useful when a compact camera needs to concentrate on a more distant or specifically defined target area. The F1.4 aperture further supports imaging under lower available light.

Because the lens is explicitly IR Corrected, it can also be considered for Day & Night camera architectures and systems that use near-infrared illumination. Engineers can review Towin’s Distortion Guide when determining whether a low-distortion optical design is appropriate for their application.

Why Low Distortion Matters

The -0.2% distortion specification is the defining optical characteristic of this lens. Low distortion helps reduce the bending of straight lines toward the edges of an image, which can improve the consistency of visual geometry.

This makes the lens particularly relevant when the camera image may be used for object positioning, visual comparison, structured observation, or applications where excessive wide-angle distortion would reduce image usability.

However, low distortion should not be confused with metrology-grade measurement accuracy. Final system performance also depends on the sensor, camera calibration, working distance, installation geometry, and image-processing algorithm.

For applications where precise focal-length selection is important, Towin’s Lens Selection Guide can help engineers evaluate sensor size, focal length, field of view, and application requirements together.

The Focal Length Calculator can also be used to estimate the focal length required for a specific target distance and framing requirement.

Designed for low-distortion focused surveillance, equipment monitoring, access control, and compact Day & Night imaging systems.

Frequently Asked Questions

Q: What type of lens is the 29mm M12 lens?
A: It is a 29mm M12 fixed focal lens featuring low distortion, IR-corrected optics, an F1.4 aperture, and a 12° horizontal field of view.

Q: What is the distortion of this M12 lens?
A: The specified distortion is -0.2%. This low distortion characteristic helps maintain more accurate image geometry compared with conventional wide-angle optics with higher barrel distortion.

Q: Is this a low distortion lens?
A: Yes. With a specified distortion of only -0.2%, the lens is appropriately classified as a Low Distortion Lens.

Q: What is the horizontal field of view?
A: The horizontal field of view is 12°. This relatively narrow FOV provides focused coverage of a defined target area.

Q: Is the 29mm lens a zoom lens?
A: No. It has a fixed 29mm focal length and therefore belongs to the Fixed Focal Lens category.

Q: What is the benefit of the F1.4 aperture?
A: F1.4 provides a relatively large aperture, allowing more light to reach the sensor. This can benefit imaging systems operating under low or changing illumination.

Q: What does IR Corrected mean?
A: IR correction is designed to reduce focus shifts between visible and near-infrared wavelengths, helping maintain consistent imaging performance when infrared illumination is used.

Q: What sensor size is this lens designed for?
A: The specified image format is 1/2″, so the lens is intended for compatible 1/2″ image sensors.

Q: Can this lens be used for precision measurement?
A: With -0.2% distortion, it fits applications needing accurate image geometry. However, measurement performance depends on the full camera system, calibration, working distance, sensor and image processing. Optical specs alone do not guarantee metrology accuracy.
