Assembly and method for identifying coatings lying on the surface of components and for determining their characteristics

摘要

The invention is directed to an arrangement for detecting coatings which are arranged on surfaces of structural component parts or objects and for determining the chemical characteristics and surface properties of these coatings. It comprises a light source for illuminating the coating to be analyzed on the surface of the structural component part and means for imaging the light source on an entrance slit over the surface of the coating to be analyzed. The entrance slit is imaged in a wavelength-dependent manner on a two-dimensional detector unit by a grating. An evaluating unit which is electrically connected to the detector unit serves to evaluate and process the signals supplied by the exposed detector elements of the detector unit.
