Abstract:
1. A method for acquisition of special spectra using a scanning microscope, comprising the following steps: a) subdividing a complete spectrum, in which at least one special spectrum is located, into at least two intervals; b) determining the intensity of the light in the at least two intervals; c) selecting one interval out of the at least two intervals in which the intensity lies above a specific threshold (T); d) subdividing the selected one interval into at least two further intervals; e) performing steps b) through c) until the size of the selected one interval corresponds to a lower limit of measurement accuracy; f) determining the location of the at least one special spectrum in the complete spectrum on the basis of the information about intensities in the at least two selected intervals; g) defining a location of the at least one special spectrum in the complete spectrum and linearly measuring the at least one special spectrum.
