New to the industry, VisionGauge Digital Optical Comparators offer many advantages over conventional comparators, including the ability to digitally compare a part to its CAD data quickly and easily, at exceptionally high accuracy. This data can also be archived and documented electronically. In contrast, traditional optical comparators require Mylar overlay charts that are time consuming to use, less precise, error prone, and difficult to document. VisionGauge Digital Optical Comparators will automatically produce an operator-independent “pass / fail” result, and display any deviation from specification by comparing a part against bi-directional tolerances at user-specified control points.
VisionGauge Digital Optical Comparators combine the capabilities of an optical comparator, video coordinate measurement machine, machine vision, and vision system. Similar to a CMM, VisionGauge Digital Optical Comparators produce highly accurate measurements in both manual and fully automated modes. The comparators feature an extensive 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.
