Abstract
The invention concerns a measuring device for the optical analysis of a diagnostic test element (10) comprising a light source (16), a photodetector (24) and a device (12) for positioning the test element (10) between the light source (16) and photodetector (24) where the light source (16) has one or several organic light-emitting diodes (OLEDs) and the OLEDs (14) for a composite structure with an imaging optics (20) and/or a photodetector (24) by means of a support substrate.
Claims24
A measuring device for optically analyzing a diagnostic test element, the measuring device comprising:
- a light source having at least one organic light-emitting diode;
- imaging optics;
- a photodetector;
- and
- a device adapted to position the test element in an optical path between the light source and the photodetector, wherein the light source forms a composite structure including a support substrate, the imaging optics and the photodetector, and wherein the support substrate is transparent.
An optical measuring device formed to photometrically analyze a diagnostic test strip, the device comprising:
- a positioning unit for the test strip;
- and
- a composite structure including a light source formed by an organic light-emitting diode, an imaging optics, a photodetector having a polymer photodiode, and a transparent support substrate formed to support the light source, imaging optics, and the photodetector.
