Arducam LN012 M12 Mount 3.6mm Low Distortion Camera Lens

The Arducam LN012 lens is compatible with any camera module or sensor board that features a standard M12 (S-Mount) thread and is designed for a 1/2.5" image sensor format. This includes many popular embedded vision boards from Arducam and other manufacturers used in Raspberry Pi, NVIDIA Jetson, and industrial machine vision systems. Ensure your camera's sensor size and mount thread match these specifications for proper integration and optimal image circle coverage.

To install the lens, carefully screw it into the M12 threaded mount on your camera module, ensuring it is seated straight to avoid cross-threading. For focusing, you will need to mechanically adjust the lens by rotating it within the mount while observing a test pattern on your sensor. Once sharp focus is achieved at your desired working distance, you may need to secure the lens with a locking screw or thread-locking compound if your camera housing supports it, as this lens does not have a built-in focus lock.

A low distortion lens minimizes optical aberrations that cause straight lines in a scene to appear curved in the captured image. This is critical for applications like machine vision measurement, barcode reading, optical character recognition (OCR), and any spatial analysis where geometric accuracy is required. It ensures that pixel coordinates in your image accurately represent real-world dimensions, improving the reliability of your computer vision algorithms and reducing the need for complex software correction.
