Precision chessboard pattern
31 x 24 mm active area
1.52 µm dimensional accuracy

The Opto Engineering PT016-024 has a 31 x 24 mm active area.

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. The optional calibration pattern holder (shown in background of photo above) is sold separately.
