The perfect vision with glasses can only be reached with the analysis and the consideration of the individual parameters of the visual glass-eye system. The video centering system achieves this by creating a three-dimensional picture, taken with only one single shot by a unique stereo camera system. The innovative light concept of the easily movable slide and the angled illumination results in an improved homogeneity over the complete measuring area. The design of the colorful illuminated LED on / off switch is not only a functional eye-catcher, furthermore it complies with the characteristics of the brand identity of Rodenstock.
