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.

Abstract: The invention relates to a device for detecting different fluorescence signals of a sample support illuminated with different excitation wavelengths. Said sample support comprises a number of samples that can be exited by different light wave-lengths for emitting differing fluorescent light. To this end, light sources (1, 3) are provided for generating rays of light or different excitation wavelengths, which can be directed toward the sample support (9) by excitation optics (5, 11). The fluorescent light (23, 45) emitted each time by the sample support (9) can be directed toward a receiver (25), which generates corresponding fluorescence signals. A mirror assembly (19) with reflective areas (19′) and transparent areas (19″) is connected between the different light sources (1, 3) and the sample support (9).

Abstract: A conveyor belt (1) leading to a sorting device (2) comprises two superimposed functional sections (3, 12), which are connected to each other via deflected intermediate sections. As a result, the structural length of the conveyor belt (1) is reduced.
