  • Arrangement and method for compensation of the temperature dependency of detectors in spectrometers
    Patent number: 7573023
    Abstract: The present invention is directed to an arrangement and the associated method for the compensation of the temperature dependency of detectors in spectrometers. In the solution according to the invention, the arrangement for compensation of the temperature dependency of detectors in spectrometers comprises an illumination unit, an entrance slit, an imaging grating, a detector and a controlling and evaluating unit. A second temperature gauge for the ambient temperature is provided in addition to an existing first temperature gauge and a temperature regulating unit. In the method according to the invention, a temperature regulating unit is controlled in such a way by a controlling and evaluating unit in the evaluation of the measurement values determined by two temperature gauges that the temperature of the detector remains constant.
