Optical Gaging Products (OGP), a manufacturer of precision multisensor metrology systems for industrial quality control, announces its Automatic Three-Position Lens Changer, available on C-Vision Lite Video Contour Projectors.

This CNC lens turret enables nine automatic, programmable magnification changes – three optical and six digital – within a CNC program. According to OGP, 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", 1" and ½" fields of view — permanently mounted in a shophardened 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 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 C-Vision Lite, the C-Vision Benchtop and the heavy-duty C-Vision Floor Model. According to OGP, C-Vision systems combine the speed and accuracy of a video measurement system with the rugged capacity of an optical comparator.
