ABSTRACT:
The invention concerns a measuring device for carrying out of chemiluminescence and/or fluorescence measurements of fluid samples, which in sample containers (22) of a sample plate (24) are contained. For analysis of a measurement light exiting from an upper measurement opening (26) of a sample container (22) found in a measurement position, a photo-multiplier (12) is provided, which for achievement of a flat device construction is provided lying down. In order that the measurement light is redirected into the entry window (36) of the photo-multiplier (12) there is provided a reflector (16) before the photomultiplier (12) in the carrier body (14) which covers over at least the measurement opening (26) of the sample container (22) to be measured, at a distance (FIG. 1).
