摘要： The invention relates to an optical detection device for chemical analyses, comprising at least one light source, at least one photoelectric detection unit and at least one measuring cell, one or more optical paths coupled to the at least one measuring cell being formed between the light source(s) and the photoelectric detection unit(s). In the course of the miniaturization of such detection devices in arrays for the simultaneous detection of a plurality of analytes, according to the prior art edge-emitting semiconductor lasers that had been separated and applied to a substrate were used. Instead of the latter, the invention provides for surface-emitting semiconductor lasers to be used as light sources, which have the advantage of comparatively simple manufacture and of requiring substantially less space. The process of separating the lasers from the mother substrate and affixing them to a foreign substrate, which was necessary hitherto, is eliminated in the detection device according to the invention.
