M7 Miniature Low Distortion Lens Applications

Wide-Angle Imaging with Low Distortion

The main advantage of this lens is the balance between wide-angle coverage and controlled distortion. With an 87.8° diagonal FOV and distortion below 1%, it provides significantly wider coverage than a standard narrow-angle lens while maintaining relatively accurate image geometry.

This makes the lens suitable for applications where both scene coverage and geometric consistency are important. It is particularly useful when an imaging system needs to observe a relatively large area without moving to an extremely wide or fisheye optical design.

For engineers evaluating the relationship between focal length, sensor size, and field of view, TOWIN’s FOV Calculator can help with the initial lens selection process.

Compact Machine Vision

The M7 × 0.35 mount makes this lens suitable for compact camera architectures where conventional larger-format industrial lenses may not be practical.

The 5MP resolution provides sufficient image detail for a range of compact inspection and recognition systems, while the 0.1m M.O.D. allows the lens to be positioned relatively close to the target.

Potential applications include:

• Compact machine vision cameras
• Embedded inspection cameras
• Small industrial vision modules
• Robotic sensing modules
• Object detection systems
• Close-range inspection equipment
• Compact automation cameras
• Embedded imaging devices

Designed for compact machine vision and embedded imaging applications requiring a wide field of view with controlled distortion.

Close-Range Imaging

With a specified 0.1m M.O.D., this lens can be considered for applications where the camera operates relatively close to the object.

The combination of 2.4mm focal length and 87.8° diagonal FOV allows a compact camera to capture a broad scene even at short working distances. This can be useful for inspection modules, embedded sensors, robotic systems, and other installations with limited camera placement options.

The actual field coverage should be evaluated according to the sensor dimensions and working distance. TOWIN’s Sensor Guide provides additional information about sensor format and lens compatibility.

Low-Distortion Optical Performance

With a specified distortion of less than 1%, this lens is well positioned for wide-angle applications where excessive image deformation would affect visual analysis.

Low distortion can be particularly valuable when objects near the edge of the image need to retain a more consistent shape. This can simplify image interpretation and reduce the impact of optical deformation on downstream vision processing.

The lens should therefore be distinguished from the 2.2mm ultra-wide-angle M7 lens, where the much larger FOV comes with substantially higher distortion.

For a deeper understanding of how distortion affects industrial imaging, see TOWIN’s Distortion Guide.

Mechanical and Optical Integration

The lens uses an M7 × 0.35 mount with a compact 0.8mm F.B.L. and 4P construction.

The short focal length provides wide-angle coverage while the compact mechanical interface makes the lens suitable for miniature camera designs. When integrating the lens into a camera housing, the available mechanical space and sensor position should be checked against the specified F.B.L.

The F2.4 fixed aperture provides a simple optical configuration for systems where exposure is primarily controlled through the camera sensor and electronic imaging parameters.

For projects involving custom optical configurations or alternative lens specifications, TOWIN’s Optical Design resources can be used as a starting point.

Lens Selection Considerations

When selecting this lens, several parameters should be considered together:

Sensor format:
The lens is specified for a 1/4″ image format. The actual sensor and required image circle should be checked during integration.

Field of view:
The 87.8° diagonal FOV provides broad scene coverage while avoiding the extreme field angles associated with ultra-wide or fisheye optics.

Distortion:
The specified distortion is below 1%, making this lens a stronger candidate for applications where image geometry matters.

Working distance:
The 0.1m M.O.D. makes it suitable for close-range applications, but the required field coverage should be verified at the intended working distance.

Focusing:
The lens uses manual focus. Focus adjustment can therefore be performed during camera assembly and system calibration.
