Optical comparators are a mainstay of shop-floor measurement, with their rugged construction and large viewing screen. Traditional comparators project images of parts using a combination of the proper illumination, lenses, and mirrors in order to make measurements. Vision measurement systems offer the advantages of full automation and highly functional software, but cannot match a comparator for shop floor toughness. Now, advances in video technology enable us to embed a high resolution video camera into the optics of a traditional comparator. Embedding a camera in the optics of a comparator allows the system to function as a traditional analog comparator or as a fully automatic vision system. The internal video camera is positioned to view the image formed by the comparator optics, allowing parts to be digitally analyzed and measured instantly on a separate computer screen. Automating inspections saves time and eliminates potential variability from multiple operators. Accuracy is also improved through the use of advanced video measuring software by measuring hundreds of points per feature in the time a typical edge sensor will measure a few. Measurement software not only allows for accurate measurement of a range of feature geometries, it can also apply dynamic tolerances, construct features from multiple measurements, and compare actual measurements directly to CAD models. CAD integration can decrease program setup time by allowing the operator to create entirely automatic measurement routines, directly from a CAD file. VidiProbe™, from Certified Comparator Products (CCP) pairs fully automatic video measuring technology with a traditional optical comparator. The integrated high resolution video camera is positioned to view the image of the part formed by the comparator optics, allowing the image to be measured with Measure-X® 2D software. The VidiProbe option is available on 14”, 16”, and 20” comparators. CCP also offers c-vision™ Video Contour Projector which gives you the proven design of a profile projector with the accuracy of a video measurement system. C-vision gives you a greater magnification range than a traditional comparator but still offers a high capacity carrying load needed for measurement of large, heavy parts. Low mag has a 3” field of view, similar to a 30” projector with a 10x lens. Certified Comparator Products 1174 Grange Hall Road Beavercreek, OH 45430 www.certifiedcomparator.com
