The very flat surface of this glass-supported dot-pattern chart ensures precise optical measurements of shading, sharpness, lateral chromatic aberration, distortion, and focal length from one shot. It is available in various sizes and is compatible with most types of cameras.

Produced by a specialized provider, this chart with specific markers lets you use Analyzer software to autonomously obtain ROI placement and all objective metrics. We test and calibrate every DOT chart in our labs before shipping to ensure the same results between two charts, and assign each chart a unique identification number to facilitate high traceability.
