Device for measuring luminescence
First Claim
1. Measurement device for carrying out luminescence measurements of fluid samples, comprising:
- a sample container (22) having an upwardly directed measurement opening;
a light detector (12) having an entry surface (36) for receiving measurement light emitted from said sample container; and
a reflector (16) which covers over the measurement opening (26) and, with maintenance of a free space (42), redirects measurement light into the entry surface (36) of the light detector, and wherein the reflector (16) is fixed to a carrier body (14) which shields from stray light.

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).
