OpenMV Ultra Wide Angle Lens M12 Mount 99° FOV

This lens is designed for OpenMV camera modules that feature a standard M12*0.5 lens mount, which includes most OpenMV Cam models like the OpenMV Cam H7. You simply unscrew the original lens and screw this one in its place. Ensure your specific OpenMV board has the standard threaded lens holder. It is not compatible with cameras that use a fixed lens or a different mounting system like C/CS-mount.

The 650nm IR cut filter is housed in a small ring at the base of the lens barrel. To remove it, gently unscrew this ring using your fingers or a small spanner wrench. This allows near-infrared light to pass, useful for night vision with IR LEDs. To reinstall it, screw the filter ring back on. Handle the optical glass carefully to avoid scratches or fingerprints during the process.

The lens produces a noticeable fisheye effect or barrel distortion, which is typical for ultra-wide-angle optics. Straight lines near the edges of the image will appear curved. For many OpenMV applications like motion detection or color blob tracking, this distortion may not be critical. If needed, you can apply software correction (undistortion) in your OpenMV IDE script using the lens correction module, though this requires calibration and adds processing overhead.
