Abstract

Light sources are provided for generating rays of light of different excitation wavelengths, which can be directed toward the sample support by excitation optics. The fluorescent light emitted each time by the sample support can be directed toward a receiver, which generates corresponding fluorescence signals. A mirror assembly with reflective areas and transparent areas is connected between the different light sources and the sample support. The mirror assembly can be displaced in such a manner that the ray of light of a light source passes through a transparent area and reaches the sample support.
