    Abstract: A device for analyzing a sample includes a measurement area at which the sample is to be located, an illumination arrangement, and first and second spectral sensors. The illumination arrangement illuminates the measurement area such that the illumination is incident on the sample. Each of the first and second spectral sensors is oriented toward the measurement area to collect illumination arriving from the measurement area. The first spectral sensor performs a spectral measurement of the sample in response to the incident illumination so as to produce spectral measurement data. The second spectral sensor measures background noise so as to produce background measurement data that provides at least a partial correction for noise in the spectral measurement data. In certain embodiments, operation of the first and second spectral sensors is switched such that the second spectral sensor performs a spectral measurement and the first spectral sensor measures background noise.

    Abstract: A method can be used for correcting background signals in captured measurement values of analog detectors, wherein measurement values of an object captured over a reference time period are analyzed and characteristic values of captured background signals are determined. What is characteristic of this is that a threshold value is determined on the basis of at least one characteristic value and by applying a calculation specification; the threshold value is applied to captured measurement values of an analog detector, and only those measurement values which are greater than the threshold value are used for a subsequent signal evaluation. A microscope for carrying out the method according to the invention is also provided.
