Apparatus for illuminating a probe plate to be examined

摘要

Apparatus for illuminating a sample plate (12) which is to be examined for example by fluorescent light excitation of the samples. This apparatus has a plurality of light-emitting diodes (15), which are arranged in an array and whose radiated light is guided in a homogeneous light field through an optical arrangement (19) onto a sample field (22). The intensity of the light field suffices in particular for generating a fluorescent light excitation of the samples (23), which can be determined by a CCD camera (29). This provides a cost-effective light source for generating a light field with sufficient intensity.
