Paper Abstract

The chromatic confocal method to measure the refractive index and thickness of membranes is developed. The method is based on the longitudinal chromatic aberration produced by a diffractive element. The identification of the maximal spectral components coming from the membranes are used for measuring its thickness or its refractive index.
