About this item

The Arducam Lens Calibration Tool – Field of View (FoV) Test Chart is a simple yet essential accessory for developers, engineers, and camera enthusiasts working on camera modules, especially in embedded vision systems. Designed as a foldable reference chart, it helps users accurately determine a camera’s field of view (FoV) and test lens distortion, alignment, and focus accuracy. Made with high-contrast printing and geometric patterns, the chart provides clear visual markers to assess how much of a scene a camera can capture at a given distance. It is especially useful when comparing different lens types, such as M12 or C/CS-mount lenses, or evaluating camera modules for applications in robotics, machine vision, security, and 3D imaging. The chart folds flat for easy storage and transport, and unfolds into a three-panel design for convenient tabletop setup. It is printed on durable, matte-finish cardstock to reduce glare and reflections during testing. Whether you're calibrating a wide-angle lens or adjusting the focus on a telephoto module, this tool helps you validate performance in a consistent and repeatable way.
