Patent ID: 7544926

Claim:
Multi-functional calibration system ( 10 ) for characterizing luminescence measurement systems, in particular spectrally resolving, wide-field and/or confocal imaging systems, comprising (a) a baseplate ( 12 ), (b) at least one calibration module ( 24 ) arranged on the baseplate ( 12 ) and including at least one calibration and/or characterization function, and (c) at least one focusing device ( 20 ) integrated in the baseplate ( 12 ) with a highly planar focusing surface ( 22 ) having reflecting and/or lumenescing properties for setting a defined measurement beam focus of the luminescence measurement systems to be calibrated, the focusing surface ( 22 ) arranged in a common plane with the at least one calibration module ( 24 ) and having a surface roughness less than the optical resolution of the luminescence measurement system.
