OGP Introduces Exclusive Technological Advancement in Video Comparator Systems

CNC lens turret allows nine automatic, programmable magnification changes within a CNC program

Published: Wednesday, September 1, 2021 - 12:00

(OGP: Rochester, NY) -- Optical Gaging Products (OGP), a world-leading manufacturer of precision multisensor metrology systems for industrial quality control, announces a technological breakthrough in value-class video comparator systems: The Automatic Three-Position Lens Changer, available on c-vision Lite Video Contour Projectors.

This CNC lens turret allows for nine automatic, programmable magnification changes—three optical and six digital—within a CNC program. The system is both parfocal and parcentral—parts on the stage stay in focus and stay centered when magnification and focal length is changed.

Three internal lenses offer 2-inch, 1-inch, and half-inch fields of view—permanently mounted in a shop-hardened motorized turret.

“Before this innovation, operators were required to manually unscrew a lens, attempt to safely store the lens, screw in a new lens, and recalibrate—a very timely task that could never be done in the middle of a program,” says Tim Fantauzzo, OGP vice president of North American Sales. “The innovative c-vision Lite lens turret system allows for these changes automatically, and as part of a CNC program, resulting in far faster, and more accurate measurement results—tying together small part feature details with larger overall part measurements.”

c-vision Lite systems are a part of the c-vision family of Video Contour Projectors from OGP—the value-class c-vision Lite, the capable c-vision Benchtop, and the heavy-duty c-vision Floor Model. c-vision systems combine the speed and accuracy of a video measurement system with the rugged capacity of an optical comparator, to create the world’s best shop-floor measuring tools for 2D measurement.
