摘要： An optical sensing unit is provided which comprises at least one sample measurement cell (20), at least one excitation light source acting upon the or each measurement cell to provide one or more sensor fields defining an array of measurement fields, a photoelectric detector array (17) for detecting the intensity of light emitted from the or each measurement cell in response to excitation light, and means for directing light emitted from each measurement field to a respective portion of the photoelectric detector array (14, 15, 16, 17). The sensing unit may be used in combination with multiplexed waveguide arrays or multiplexed planar capillary chromatography or electrophoresis chips.

摘要： The invention relates to a sensor platform based on at least two planar, separate, inorganic dielectric waveguiding regions on a common substrate and to a method for the parallel evanescent excitation and detection of the luminescence of identical or different analytes. The invention relates also to a modified sensor platform that consists of the sensor platform having the planar, separate, inorganic dielectric waveguiding regions and one or more organic phases immobilised thereon. A further subject of the invention is the use of the sensor platform or of the modified sensor platform in a luminescence detection method for quantitative affinity sensing and for the selective quantitative determination of luminescent constituents of optically opaque solutions.

摘要： An optical detector for carrying out chemical analyses has at least one light source, at least one electric detection unit and at least one measurement cell. One or several optical paths coupled to the measurement cell(s) are formed between the light source(s) and the photoelectric detection unit(s). Separate edge-emitting semiconductor lasers applied on a substrate have been used in the prior art when miniaturising such detection devices arranged in arrays to simultaneously detect a plurality of analytes. The invention provides instead the use of surface-emitting semiconductor lasers as light sources, which have the advantage of being relatively easy to produce and of occupying considerably less space. The process hitherto required to separate the laser from the mother substrate and to glue it on a foreign substrate can be dispensed with in the disclosed detector.
