Abstract
A measuring assembly comprises a supporting element transparent to excitation and measurement radiation, which is provided with a number of preferably different luminescence-optical sensor elements on a first boundary face. Via a second boundary face excitation radiation can be picked up, and a third boundary face is used to supply measurement radiation of the sensor elements to a detector of an evaluation unit. The direction of the excitation radiation is essentially normal to that of detection. The preferably different sensor elements are connected by a common sample channel, and optical and/or temporal separation of the measurement radiation of the individual sensor elements is provided.
