Optical Gaging Products’ automatic three-position lens changer
Optical Gaging Products (OGP) has developed an automatic three-position lens changer to improve the productivity of its video comparator system which is available on OGP’s c-vision Lite Video Contour Projectors.
This CNC lens turret enables nine automatic, programmable magnification changes – 3 optical and 6 digital – within a CNC program. The system is both parfocal and parcentral in which 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 shop-hardened motorized turret. The company says the c-vision Lite lens turret system enables automatic lens changes as part of a CNC program, resulting in faster and more accurate measurement results. The system is designed to tie together small part feature details with larger overall part measurements.
The c-vision Lite systems are a part of the c-vision family of video contour projectors from OGP, including the value-class c-vision Lite, c-vision Benchtop and heavy-duty c-vision Floor Model. The c-vision systems are said to combine the speed and accuracy of a video measurement system with the rugged capacity of an optical comparator, to create the world’s best shopfloor measuring tools for 2D measurement.
