Abstract
Optical thickness of thin transparent layers was determined from the extinction condition for the interference of monochromatic light on the layer. Several ways have been suggested for the determination of the order of interference of the extinction fringes, based on the fringe shifts with the wavelength. The method has proved useful in the determination of the optical thickness of the fracture surface layer of polymers, but the range of its possible applications is wider.
