In a method for determining optical properties by measuring intensities at a thin layer, light is directed into the thin layer and passes through a beam splitter, which directs a first part of the light onto the thin layer and a second part of the light onto a reference detector. Interference of the first part of the light in the thin layer is detected via a high-resolution detector and forwarded to an evaluating unit, which determines the reflection and/or transmission coefficients, which are correlated with the optical layer thickness through a comparison using at least one database stored in the evaluating unit. The optical layer thickness is obtained as a gray value modification by way of a gray scale value analysis and a conversion factor stored in the at least one data base. A corresponding device and intended uses of the method and device are also described.
