Abstract

A device for the measurement of chemical and/or biological samples, in particular by means of luminescence spectroscopy, comprises an irradiation unit, a sample receiver, at least one optical unit and a detector unit. The color marker in the sample, which contains at least one color marker, is stimulated by irradiation into producing luminescence and gives off light. The light emitted by the color markers is detected by detectors in the detector unit. According to the invention, the measurement results may be improved by the irradiation unit generating pulsed irradiation. The irradiation unit is thus preferably controlled by a control unit in such a way that the irradiation pulses impinge on the sample in a temporal sequence.
