    摘要: Optical detection apparatus for chemical analyses of small volumes of samples has light sources (21) to emit induction light, a measuring cell (7) for the sample, photoelectric sensing elements (22) to receive light coming form the sample in the measuring cell (7), as well as beam-conducting means for the induction light or the light from the sample. In the apparatus, several essentially planar, laminar components (2-7) are arranged in a sandwich structure, whereby the components (2-7) contain the light sources (21), the measuring cell (7), the photoelectric sensing elements (22), and also the beam conducting means.

    摘要: In the optical detection device (1), the excitation light guide (11) and the emission light guide (12) form a structural unit having the end face (14) facing the fluorescence changer (4). The end face (14) physically corresponds substantially to one of the boundary surfaces of the two light guides (11, 12). As a result, the detection device (1) can be separated in a simple manner into an optical part and a mechanical part which are in optical contact only by way of the end face (14). All of the elements in the optical light path are connected in a mechanically stable manner by means of the index-matching medium 20, as a result of which the light between the light source (10) and the photoelectric sensor (13) propagates only in media having a comparable refractive index. The light source (10) is preferably a light-emitting diode. A plurality of those detection devices can be combined to form a compact detection apparatus with which the substance (3) can be examined with regard to several constituents in one measuring operation.
