Abstract
A measuring chamber such as a flow-through chamber includes a bottom part and a top part which are at least partially transparent to the excitation and measuring radiation and together form a measuring channel, and luminescence-optical sensor elements positioned in a sensing area. The bottom part and the top part each are provided with a longitudinal groove, together constituting the measuring channel. The sensor elements are placed in the longitudinal grooves of the bottom part and the top part, each of which elements is coated with an optical cover layer covering the entire sensing area.
