Abstract

The invention relates to an arrangement for the detection of biochemical or chemical substances using fluorescent light excitation, and to a process for its production, which can be used in a variety of fields, for example in biotechnology, in molecular medicine, in pharmaceuticals development and for the analysis or various chemical substances. A relatively simple structure is intended to provide the invention with the possibility of being able to carry out the detection of a large number of samples in a very short time with a high degree of accuracy. To that end, a laminar substrate is formed with a locally defined structure in order to detect different samples. Advantageously, on the detector side, a lens array designed according to the structuring can be used to project the fluorescent light from the different samples on to a detector array. It is, however, also possible to place a detector array matched to the structuring of the substrate on the substrate, or arrange it there.
