Abstract

In the measurement system for detecting optical signals of microassays, the signal- generating test objects 5 are arranged on an investigation surface of a planar carrier 4. The planar carrier 4 is, in particular, a microtitre plate for biological objects. In principle, the measurement system comprises an optical imaging arrangement which reduces the size of the test objects 4 to be measured in such a way that all the objects are imaged completely on a two-dimensional, photosensitive image sensor 6. For imaging, a high-resolution glass-fibre taper element 1 having a large-area 2 and a small-area end 3 is used in this case, whose end surfaces 2, 3 are selected such that the large-area end surface 2 corresponds at least to the investigation surface of the carrier 4 and the small-area end surface 3 corresponds to the size of the image sensor 6, the ratio of the end surfaces 2, 3 producing the scale of reduction of the optical imaging arrangement in order to image the investigation surface of the carrier 4 completely onto the image sensor 6.
