Abstract

An arrangement for determining characteristics or parameters of a sample, or a layer formed on or in the sample, has detectors, spatially resolving spectral analysis of electromagnetic radiation within a wavelength interval, provided in rows or in a row and column arrangement, whereby electromagnetic radiation emitted from a broadband radiation source is incident on the detectors after reflecting off, and/or passing through, the sample, or layer formed on or in the sample, upon which is observed a homogeneous intensity of the electromagnetic radiation, and an electronic evaluation unit connected to the detectors compares the spatially-resolved and wavelength-resolved signals detected by the detectors with a theoretical wavelength dependent progression of the respective radiation intensities obtained through simulation or with a progression obtained by calibration on a known sample, in order to obtain information for the measurement position detected, and determine the spatially-resolved distribution of the characteristics or parameters.
