M5 Miniature Low Distortion Lens Applications

The defining advantage of this 2.5mm M5 lens is its combination of miniature mechanical integration and less than 1% distortion. It is designed for camera systems that need broader scene coverage than a conventional narrow-angle lens while avoiding the pronounced geometric deformation associated with fisheye optics.

Low Distortion Machine Vision

With distortion specified below 1%, this lens is particularly well suited to machine vision systems where maintaining consistent object geometry is important.

The 60° horizontal FOV provides useful scene coverage without requiring an extreme wide-angle optical design. This can make the lens appropriate for compact inspection cameras, object positioning modules, visual detection systems, and localized industrial imaging.

Smart Embedded Monitoring

The combination of 70° diagonal FOV and less than 1% distortion makes this lens suitable for compact monitoring systems that need a relatively broad view without the strong curvature associated with fisheye optics.

The integrated IR cut filter also makes the optical configuration suitable for visible-light camera modules used in smart devices and embedded monitoring equipment.

Ultra-Low Distortion Optical Performance

The less-than-1% distortion specification is the defining optical characteristic of this lens. In miniature optics, achieving broad coverage while maintaining controlled image geometry can be challenging because increasing the field of view often introduces stronger barrel distortion.

This 2.5mm M5 lens provides a 70° diagonal FOV while keeping specified distortion below 1%. As a result, it can be considered for compact vision applications where image geometry matters but the system cannot accommodate a larger industrial lens.

When evaluating a lens, distortion should be considered together with focal length, sensor format, field of view, and working distance. TOWIN’s Lens Selection Guide provides additional information for comparing these parameters.

Compact Mechanical Integration

This lens uses an M5×0.35 mount with a 1.08mm BFL, making it suitable for optical assemblies with extremely limited space behind the lens.

The fixed F2.4 aperture, fixed iris, manual focus, and fixed zoom configuration are intended for applications where the optical setup can be established during camera assembly.

The 0.1m minimum object distance also provides flexibility for relatively close-range imaging configurations when the working distance and sensor setup are properly matched.

Sensor & Field-of-View Matching

The lens is specified for a 1/5″ image format and provides a 70° diagonal, 60° horizontal, and 45° vertical field of view.

Before integrating the lens into a camera module, the sensor format should be checked against the optical image format. TOWIN’s Sensor Guide provides guidance on sensor and lens compatibility.

For projects where the required viewing area needs to be calculated from working distance and sensor dimensions, the FOV Calculator can help evaluate the required optical configuration.

Frequently Asked Questions

Q: What is the focal length of this M5 lens?
A: The focal length is 2.5mm.

Q: What field of view does this 2.5mm M5 lens provide?
A: The specified field of view is 70° diagonal, 60° horizontal, and 45° vertical.

Q: What is the distortion specification?
A: The specified distortion is less than 1%, making ultra-low distortion the primary optical characteristic of this lens.

Q: What sensor format is this lens designed for?
A: The lens is specified for a 1/5″ image format.

Q: What type of mount does this lens use?
A: It uses an M5×0.35 miniature mount for compact camera integration.

Q: Is this a fisheye lens?
A: No. Although it provides a relatively broad 70° diagonal FOV, its less-than-1% distortion is designed for controlled image geometry rather than the strong distortion characteristic of fisheye optics.

Q: Does the lens have an IR cut filter?
A: Yes. The lens construction is specified as 3P + IR cut filter. The presence of an IR cut filter does not by itself classify the lens as IR corrected.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m.
