12mm M12 Ultra Low Distortion Lens Applications

Core Application Scenes

The defining feature of this 12mm M12 lens is its less than 0.1% distortion performance. This makes it particularly suitable for machine vision applications where geometric accuracy is important and distortion can affect measurement results, feature positioning, or automated image analysis.

The lens can be used for dimensional inspection, component measurement, precision defect detection, barcode and code recognition, PCB inspection, and automated quality control. Its 8MP resolution provides sufficient image detail for systems that need to distinguish small features while maintaining a controlled field of view.

The 12mm focal length and 0.1m minimum object distance are suitable for fixed-position inspection setups where the target occupies a defined portion of the image. The F8.0 aperture is particularly appropriate for systems using controlled illumination, where optical consistency and depth of field are prioritized over maximum light collection.

Designed for precision machine vision and low-distortion industrial inspection applications.

Frequently Asked Questions

Q: What makes this 12mm M12 lens different from a standard low distortion lens?
A: Its specified distortion is below 0.1%, providing exceptionally controlled image geometry for applications where even small amounts of optical distortion can affect inspection or measurement.

Q: Is this lens suitable for precision machine vision?
A: Yes. The combination of 8MP resolution, <0.1% distortion, a 2/3″ image format, and fixed 12mm focal length makes it suitable for precision inspection and automated visual analysis.

Q: What field of view does the lens provide?
A: On a 2/3″ sensor, the lens provides a 49° diagonal, 40° horizontal, and 30° vertical field of view.

Q: What is the minimum object distance?
A: The M.O.D. is 0.1m, or 100mm, allowing the lens to be used for relatively close-range inspection.

Q: Why is low distortion important in machine vision?
A: Low distortion helps maintain the actual geometric relationships of objects in the captured image. This can be important for dimensional measurement, feature positioning, inspection, and image-based analysis.

Q: Does the IRCF construction mean this is an IR corrected lens?
A: Not necessarily. IRCF is part of the optical construction, but it does not by itself establish that the lens is specifically corrected for infrared wavelengths. Therefore, it is not classified as an IR Corrected Lens based solely on this specification.

Q: Is F8.0 suitable for low-light machine vision?
A: F8.0 is a relatively small aperture and is generally better suited to applications with controlled or sufficient illumination. It can be advantageous when the system prioritizes optical stability and depth of field rather than maximum light transmission.
