Low Distortion Lens – CCL14034MP

CCL14034MP is 3.4mm High-Quality low distortion lens for Achromatic, F2.8 M7X0.35 mount lens, 1/4″ high resolution 2-Megapixel CCTV lens.

3.4mm M7 Low Distortion Miniature Lens

The 3.4mm M7 low distortion miniature lens is designed for compact imaging systems that require a small optical footprint, controlled distortion, and reliable close-range imaging. With a 70° diagonal field of view, <1% distortion, F2.8 aperture, and 0.1m minimum object distance, this lens provides a practical balance between coverage and image geometry for embedded vision applications.

Its M7×0.35 mount, 0.8mm back focal length, fixed iris, and manual focus make it suitable for compact cameras where installation space is limited. The 4P optical construction supports lightweight and space-constrained camera designs.

M7 Miniature Low Distortion Lens Core Highlights

<1% Low Distortion Imaging

With distortion controlled below 1%, this lens is suitable for applications where image geometry and object proportions need to remain relatively accurate. The controlled distortion is particularly useful for inspection, measurement-oriented imaging, and machine vision systems where excessive barrel distortion can affect image interpretation.

For more information about optical distortion and its practical impact, see TOWIN’s Distortion Guide.

Compact M7×0.35 Mount

The M7×0.35 mount provides a compact mechanical interface for miniature camera modules. Its small form factor makes the lens suitable for embedded cameras and vision devices where a standard C-mount or CS-mount lens would be too large.

The lens can be considered alongside TOWIN’s range of M8/M7/M6/M5/M3.5 Small Mount Lenses when selecting an optical solution for space-constrained equipment.

70° Diagonal Field of View

The 70° diagonal FOV provides a useful viewing range without relying on an extreme wide-angle or fisheye optical design. The 60° horizontal and 40° vertical fields of view make the lens appropriate for compact cameras that need moderate scene coverage while maintaining controlled image geometry.

0.1m Minimum Object Distance

A minimum object distance of 0.1m enables close-range imaging in compact inspection and embedded vision systems. This makes the lens useful when the camera must be installed relatively close to the target while still covering a practical field of view.

M7 Miniature Low Distortion Lens Applications

This 3.4mm M7 lens is particularly suitable for compact systems where lens size and controlled distortion are both important.

Compact Machine Vision

The <1% distortion specification can help preserve object geometry in compact inspection cameras. The 70° diagonal FOV provides sufficient coverage for close-range inspection without the severe geometric distortion associated with fisheye optics.

Robotics and Compact Vision Modules

The small mechanical format is useful for robotic or embedded vision modules where optical size and installation clearance are important design constraints.

Designed for compact machine vision, embedded imaging, and close-range inspection applications.

Technical Selection Considerations

When integrating this M7 lens into a camera system, several parameters should be evaluated together.

First, verify that the camera sensor is compatible with the 1/4″ image format. Using a sensor significantly larger than the specified image format may result in insufficient image coverage or vignetting.

Second, consider the 70° diagonal field of view in relation to the camera-to-target distance. A wider FOV covers more of the scene, while a longer focal length generally provides a narrower view and greater image magnification.

Third, the <1% distortion specification is important when the application involves object positioning, dimensional inspection, or image-based measurement. If distortion requirements are particularly strict, the complete camera-lens system should be evaluated rather than relying only on the nominal lens specification.

Finally, the 0.8mm BFL and M7×0.35 mounting interface should be checked against the mechanical design of the camera module before integration.
