Contactless measuring device for spectacles frame

摘要

The measuring device provides the 3-dimensional shape of a peripheral groove in a spectacles frame using a light source (1), providing a beam directed onto the groove and an optical imaging system for imaging the reflected light onto a photo-optical detector, with the shape of the groove determined using a triangulation method. The photo-optical detector is supported centrally relative to the spectacles frame, with rotation of the measured spectacles frame relative to the light source, the imaging system and the photo-optical detector.
