M6 Low Distortion Lens Core Highlights

• <1% Low Distortion — Provides highly controlled image geometry for applications where excessive optical distortion can affect visual analysis.
• 5MP Imaging — Designed for 1/4″ 5MP camera systems requiring compact optics with detailed image capture.
• Ultra-Compact M6×0.35 Mount — The M6 interface is suitable for highly space-constrained camera modules and miniature imaging equipment.
• 0.1m Minimum Object Distance — Supports close-range imaging applications where the camera must operate near the target.
• 68.7° Diagonal FOV — Provides useful scene coverage while maintaining the controlled distortion characteristics of the optical design.
• C.R.A. <25° — The specified chief ray angle supports optical integration with compatible image sensor configurations.

M6 Low Distortion Lens Applications

This 3.3mm M6 lens is designed for compact imaging systems where small mechanical dimensions, low distortion, high resolution, and close working distances are important. Its <1% distortion makes it particularly suitable when maintaining natural image geometry is more important than achieving an extremely wide fisheye field of view.

Designed for miniature low-distortion imaging applications.

Compact Machine Vision

The combination of 5MP resolution and less than 1% distortion makes this lens suitable for compact machine vision systems that require consistent image geometry. It can be used for visual inspection, object detection, positioning, classification, and other imaging tasks where image deformation should be minimized.

The 68.7° diagonal FOV provides useful coverage for relatively close targets without introducing the severe geometric deformation associated with fisheye optics.

Close-Range Embedded Imaging

With a minimum object distance of only 0.1m, this lens is particularly suitable for compact cameras positioned relatively close to the imaging target.

The M6×0.35 mount and 1.43mm BFL also make it suitable for optical assemblies where installation space is highly restricted.

Potential applications include embedded inspection modules, compact optical sensors, small monitoring cameras, and specialized imaging equipment.

Robotics Vision

Compact robotic vision modules often require small optical assemblies that can provide sufficient scene coverage without excessive distortion. The 3.3mm focal length and <1% distortion provide a practical combination for object observation, positioning, and visual inspection.

The short 0.1m M.O.D. is also useful for applications where the camera operates close to robotic components or inspection targets.

See TOWIN’s Robotics Vision solution for related applications.

Compact Inspection Systems

For inspection equipment with limited internal space, the M6×0.35 mounting interface can simplify integration into small camera housings.

The 5MP resolution and low-distortion optical design make the lens suitable for applications where visual details and relatively accurate object geometry are both required.

Why Low Distortion Matters

Distortion is an important consideration when a camera is used for measurement, inspection, positioning, or object analysis. Excessive barrel or fisheye distortion can change the apparent geometry of objects near the edges of an image.

With distortion specified below 1%, this 3.3mm M6 lens is designed around controlled image geometry rather than extreme wide-angle coverage. This makes it a better fit for applications where straight-line representation and consistent object proportions are important.

The 68.7° diagonal field of view provides useful coverage while keeping the optical design focused on low distortion.

Close-Range Imaging Capability

The 0.1m minimum object distance is one of the notable characteristics of this lens. It allows the camera system to be positioned relatively close to the target while maintaining the specified optical configuration.

This can be useful in compact inspection systems, embedded cameras, robotic equipment, and other applications where the camera cannot be installed far away from the object.

When designing the complete imaging system, the required working distance, target size, sensor format, and field of view should be evaluated together.

TOWIN’s FOV Calculator can help estimate the field of view required for a particular imaging setup.

Lens Selection Considerations

Before selecting this lens, confirm that your camera uses a 1/4″ image format and supports an M6×0.35 optical interface.

The 3.3mm focal length provides a 68.7° diagonal field of view, while the <1% distortion specification makes this lens more suitable for controlled image geometry than extreme wide-angle or fisheye applications.

The 1.43mm BFL and <25° C.R.A. are also important when integrating the lens with the camera sensor and mechanical housing.
