Arducam LN009 M12 Mount 1.71mm f/2.2 Ultra-Wide Lens

No, the LN009 lens is not directly compatible with the official Raspberry Pi Camera Module V2, as that module has a fixed lens. To use this lens, you need a camera module board that supports interchangeable M12 lenses, such as the Arducam B0031 or B0103, which include an M12 lens holder. You would mount the LN009 by screwing it into that holder.

The built-in 650nm IR-cut filter blocks near-infrared light wavelengths above 650nm from reaching the camera sensor. This optimization ensures the lens captures colors accurately under visible daylight conditions, preventing IR contamination that can cause color shifts. It is ideal for applications requiring true-to-life color reproduction, such as daylight photography, video conferencing, or color-based machine vision tasks.

The Arducam LN009 lens features manual focus adjustment. To focus, you gently rotate the lens barrel while it is mounted on your compatible M12 camera board. Point the camera at a detailed subject, preferably at the intended working distance, and rotate the barrel until the image appears sharpest on your monitor or in your captured images. It may require small, incremental adjustments for optimal clarity.

The LN009 lens is designed for camera modules that use the standard M12 threaded lens mount and a 1/3" sensor format. It is explicitly compatible with Arducam's own modules like the B0031 (for Raspberry Pi) and B0103 (for Arduino). It will also work with any other third-party camera board that incorporates a proper M12 lens holder, but always verify the sensor size and holder thread compatibility before purchase.
