Chessboard calibration pattern, 208 x 208
This item has been discontinued. Please contact us for substitutes.All lenses, even precision telecentric lenses, introduce some image distortion. In addition, alignment tolerances between lenses and camera sensors, as well as between the camera and the part, reduce the overall accuracy of inspection systems. However, common software algorithms, combined with a precise calibration target, can reduce distortion to near zero.
This chrome-on-glass pattern, manufactured using photolithography, has high geometrical accuracy. When combined with appropriate software, it will maximize the accuracy of inspection and metrology systems.
This pattern has a chessboard layout. Calibration pattern holder is sold separately.
