Non-destructive measurement of antireflective coatings on curved surfaces


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.
