Any machine vision lens (either telecentric or not) shows some amount of distortion. In addition to barrel or pincushion distortion, changes in the view angle or misaligned components will affect the image symmetry and generate the so called thin prism or keystone effect.

Imaging and metrology applications often require to minimize distortion, which can be software-corrected by analyzing the image of a precision pattern whose geometrical features are well known.

For this reason Opto Engineering® offers a full range of patterns optimized for software calibration compatible with most Opto Engineering® telecentric lenses.

The chessboards are realized with two different processes in order to provide the best solution depending on the requirements:

Chrome on glass, for leading edge applications;
Film on glass, for a perfect synthesis of performance and cost effectiveness.

Moreover, a certified version is available: standards and equipment used for calibration have been calibrated traceable to the National Institute of Standards and Technology (N.I.S.T.), in accordance with procedures set forth in ISO/IEC 17025-2005 and ANSI/NCSL Z540-1-1994.
