Arducam LN014 M12 Mount 2.1mm f.l. Low Distortion Camera Lens

No, the official Raspberry Pi Camera Module V2 uses a fixed lens and does not have an M12 lens mount. The LN014 requires a camera board with a compatible M12 lens holder, such as specific Arducam modules (e.g., B0031, B0103). You would need to replace the entire camera module board, not just the lens, to use this optic.

Distortion under 1% means the lens introduces minimal geometric warp, such as barrel or pincushion effects. This is critical for machine vision, measurement, and surveillance applications where accurate spatial representation of objects is necessary. It ensures straight lines appear straight and objects retain their true proportions across the entire image frame, unlike fisheye lenses.

Yes, the 650nm IR-cut filter blocks infrared light to improve color accuracy in visible-light conditions, which is ideal for daytime imaging. However, it will reduce sensitivity in pure IR illumination setups. For dedicated night vision using IR LEDs, you would need a lens without an IR-cut filter or one that is explicitly designed for IR transmission.

First, ensure your camera board has an M12 mount. Thread the lens into the mount clockwise until snug—do not overtighten. For focusing, point the camera at a detailed target, loosen the locking screw on the lens barrel slightly, rotate the front lens element to achieve sharp focus, then retighten the locking screw to secure the focus setting. Always handle the lens by its barrel to avoid touching the glass elements.
