Abstract: A method for the quantitative real time analysis of fluorescent samples is provided, at which each of the samples is excited to fluoresce by a sample individual light source (12) and the intensity of the light which is emitted by the samples is measured. For a highly precise measurement of even low light intensities for the purpose of reduction of the analysis time, each light source (12) is switched on and off-during a defined interval by a clocked pulse sequence of constant pulse frequency alternately. The measurement of the intensity of the emission light during these intervals is exclusively performed during the switch-on phases of the light, source (12).

Abstract: A device for photometric measurement of several samples (12) that are exposed to radiation from a light source (14) associated therewith. The light modified by the samples (12) is intercepted by an optical device (19) and is guided as a sum of all the light radiated from all samples (12) to at least one sensor (27) for measuring the intensity and evaluation thereof in an evaluation device (32) arranged downstream.
