Arducam LN069 100° Low Distortion M12 Lens w/ Adapter for Raspberry Pi HQ Camera

First, remove any existing lens from your Raspberry Pi HQ Camera module. Take the included M12 lens adapter and screw it onto the camera's CS-mount thread. Then, carefully screw the Arducam LN069 lens into the adapter until it is snug. Avoid over-tightening. No tools are required, and the process takes less than a minute for a secure, stable mount ready for your vision application.

The low distortion specification, rated at less than -1.5%, means the lens introduces minimal bending or warping of straight lines at the edges of the image. This is critical for computer vision tasks like object measurement, spatial mapping, and accurate edge detection, as it ensures the captured image is a true geometric representation of the scene, improving algorithm reliability and precision.

This lens has a standard M12 mount. It can physically attach to any camera module with a compatible M12 or CS-mount (using the included adapter). However, optimal performance is guaranteed with the Raspberry Pi HQ Camera due to its 1/2.3" sensor size matching the lens's optical format. For other sensors, you must verify the sensor size, flange focal distance, and mount compatibility to avoid vignetting or focus issues.

No special software is required for the lens itself. You use the standard Raspberry Pi OS camera software stack. Utilize `libcamera` or the legacy `raspistill`/`raspivid` commands to capture images and video. For computer vision, employ OpenCV or Picamera2 libraries in Python. The lens is a passive optical component; your existing camera configuration and code will work immediately after physical installation.
