Patent ID: 7016032

Claim:
A device for calibrating an optical detection channel for a two-dimensional, spatially dependent radiation measurement for multi-specimen carriers, particularly microtitration plates, in which the radiation of a plurality of specimens is to be measured photometrically in a darkened measurement chamber, comprising: a plate-shaped housing which is manufactured in the shape and size of a multi-specimen carrier under examination; said housing having, on a side facing a detection channel, a large-area rectangular window whose size is adapted to the surface of said multi-specimen carrier under examination; said surface of said multi-specimen carrier being provided with wells; a luminescent foil being provided inside said housing which is arranged parallel to said window so as to cover its surface; and a power source and control units being provided in said housing for controlling the luminescent foil, so that the luminescent foil can be controlled for homogeneous emission of luminescent light through the window of said housing in different intensity levels.
