The comparators, developed by VISIONx Inc. of Pointe-Claire, Quebec, claim to offer many advantages over conventional comparators, including the ability to digitally compare a part to its CAD data.

This data can be archived electronically. The system automatically produces an operator-independent “pass/fail” result, and displays any deviation from specification by comparing a part against bi-directional tolerances at user-specified control points. Similar to a CMM, the comparators produce accurate measurements in both manual and fully automated modes. The comparators feature a set of machine vision tools to carry out pattern matching, color verification, defect detection and more. A very high resolution imaging system features detailed inspection of subjective properties, such as surface finish verification, digital image collection, annotation and electronic distribution.
