    Abstract: The invention relates to a procedure for the investigation of the physical properties of thin layers using polarised light to irradiate the layer to be investigated and guiding the reflected or transmitted light onto an imaging system. Optical waveguide modes are excited in the layer to be investigated by irradiation with the polarised light.

    Abstract: The invention relates to a method for determining the refractive index and layer thickness of ultrathin layers. In order to determine the refractive index and/or thickness of layers having layer thicknesses 1 mu m, layers which are applied to a solid substrate are recorded by means of surface/plasmon microscopy as a function of the angle of incidence of the irradiating laser beam. It is possible in this way to determine layer thicknesses with a vertical resolution >/= 0.1 nm in conjunction with simultaneous lateral resolution >/= 5 mu m.
