25mm M12 8MP Low Distortion Machine Vision Lens

This 25mm M12 machine vision lens is an 8MP fixed focal lens designed for industrial imaging, machine vision inspection, measurement, and precision recognition applications. With a 2/3″ image format, 25° diagonal FOV, and TV distortion below 0.1%, it delivers highly accurate image reproduction for applications where geometric consistency and image detail are critical.

The F2.8 fixed aperture, 0.2m minimum object distance, and compact M12×0.5 mount make this low distortion lens suitable for space-constrained vision systems, embedded cameras, and industrial inspection equipment.

Low Distortion Machine Vision Lens Core Highlights

• 8MP high-resolution imaging supports detailed inspection and recognition tasks using 2/3″ sensors.
• Ultra-low distortion below 0.1% helps maintain accurate object geometry for measurement and machine vision applications.
• 25mm fixed focal length provides a relatively narrow 25° diagonal FOV for targeted imaging of objects at controlled working distances.
• Compact M12×0.5 mount enables integration into embedded cameras and space-constrained industrial vision systems.
• 0.2m M.O.D. supports close-range inspection while the F2.8 fixed aperture provides a stable optical configuration.

Low Distortion Machine Vision Lens Applications

Core Application Scenes

This 25mm low distortion M12 lens is designed for applications where image geometry, resolution, and consistent target reproduction are more important than a wide viewing angle. Its 25mm focal length and 0.1% maximum TV distortion make it particularly suitable for controlled-field imaging and precision inspection.

Typical applications include:

• Machine vision inspection
• Dimensional measurement
• Industrial quality control
• Electronic component inspection
• PCB and semiconductor inspection
• Barcode and code recognition
• Part identification
• Small-object inspection
• Robotic vision
• Factory automation
• Precision object recognition

Designed for precision machine vision and industrial inspection applications.

The 2/3″ image format and 8MP resolution should be matched with the camera sensor specifications during system design. Our Sensor Guide can help engineers evaluate sensor and lens compatibility.

Optical Design Considerations

The 25mm focal length produces a relatively narrow field of view, making this lens more suitable for targeted inspection than large-area scene coverage. When selecting the working distance and camera position, engineers should consider the required object size, sensor dimensions, and desired field of view.

For initial lens selection, use the Lens Selection Guide or calculate the required viewing range with our FOV Calculator.

The combination of 8MP resolution and <0.1% TV distortion is particularly valuable when image coordinates or object dimensions need to remain highly consistent across the captured image.

Frequently Asked Questions

Q: What applications is this 25mm M12 lens suitable for?
A: It is suitable for machine vision inspection, dimensional measurement, industrial quality control, component inspection, barcode recognition, robotic vision, and other applications requiring high resolution and very low distortion.

Q: What makes the lens suitable for precision measurement?
A: The lens provides 8MP resolution and TV distortion below 0.1%, helping maintain accurate object geometry and reduce image deformation during measurement and inspection.

Q: What sensor size is this lens designed for?
A: The lens supports a 2/3″ image format. The actual system performance should also be evaluated against the camera sensor’s resolution, pixel size, and active image area.

Q: Is this lens a wide-angle lens?
A: No. With a 25° diagonal FOV, this lens is better described as a targeted or relatively narrow-FOV lens. Its 25mm focal length is more suitable for controlled inspection areas than wide-area imaging.
