Learn more„Variogon" is the brand name for a vario-lens made by Schneider-Kreuznach. But what is a vario-lens? It is a lens that has no fixed focal length and can be changed by the user with certain limitations. This is accomplished without having to bring the image of the subject into focus again and again each time the focal length is changed. A lens of this kind is also known as a zoom lens.

To minimize disruptive reflection losses, optical components such as lenses and eyeglasses are now equipped with highly effective antireflective coatings. However, the measurement methods used in quality control using scanning spectrophotometers are often non-destructive in practice and can hardly be used at arbitrary locations on a curved surface. A special measurement head design in conjunction with a diode array spectrometer provides a solution.
