M7 Miniature Low Distortion Lens Core Highlights

• Low -1.5% Distortion — Provides controlled image geometry for applications where straight-line representation and consistent imaging are important.
• 3.8mm Short Focal Length — Offers a practical field of view while maintaining a compact optical configuration.
• Compact M7×0.35 Mount — Designed for miniature camera modules and space-limited optical assemblies.
• 2MP Resolution — Suitable for 1/4″ camera systems requiring reliable image capture for embedded and industrial applications.
• Integrated IR Cut Filter — The 4P optical construction includes an IR cut filter for visible-light imaging applications.

M7 Miniature Low Distortion Lens Applications

The combination of a compact M7×0.35 mechanical interface, 3.8mm focal length, 1/4″ image format, and -1.5% distortion makes this lens suitable for embedded imaging systems where both physical size and image geometry matter.

Embedded Camera Modules

The M7×0.35 mount and 1.2mm BFL make this lens suitable for compact camera assemblies where installation space is restricted. It can be integrated into small embedded vision devices, monitoring modules, and imaging equipment.

Designed for compact embedded imaging applications.

Low-Distortion Machine Vision

With distortion specified at only -1.5%, this lens is better suited to applications that require more controlled image geometry than conventional highly distorted miniature optics.

It can be considered for compact inspection cameras, object detection systems, automated imaging modules, and industrial cameras where excessive barrel distortion could reduce image usability.

Robotics Vision

Compact robotic camera modules often have limited optical installation space. The M7 mount provides a small mechanical footprint while the 3.8mm focal length provides practical scene coverage.

The lens can be used in robotic vision modules for object observation, equipment monitoring, compact navigation cameras, and other embedded imaging applications.

Smart Monitoring & Embedded Security

The 68° diagonal field of view and low distortion make this lens suitable for compact monitoring systems where a controlled perspective is preferred over an extreme fisheye view.

The integrated IR cut filter is designed for visible-light imaging systems and can be useful in compact monitoring camera modules.

Why Choose a Low Distortion M7 Lens?

Miniature camera lenses often use very wide-angle optical designs to achieve greater scene coverage, but this can introduce substantial barrel distortion. This 3.8mm M7 lens takes a different approach by specifying distortion at only -1.5%.

That makes it particularly relevant when the camera needs a compact optical assembly without the extreme geometric distortion associated with fisheye lenses.

When selecting a lens for an imaging system, sensor format, focal length, field of view, distortion, and mechanical dimensions should be considered together. TOWIN’s Lens Selection Guide provides additional information for comparing these optical parameters.

You can also use the FOV Calculator to evaluate the field-of-view requirements of your camera system.

Installation & Optical Considerations

This lens uses an M7×0.35 mount and has a specified BFL of 1.2mm, making mechanical compatibility especially important when integrating it into a custom camera module.

The lens uses a fixed F2.8 aperture, fixed iris, manual focus, and fixed zoom configuration. Its M.O.D. is 0.1m, which makes it suitable for relatively close-range imaging applications where the specified optical conditions are appropriate.
