Abstract:
1. An apparatus for photometrically testing several specimens ( 12 ) that are each irradiated by an associated light source ( 14 ), the light, which is altered by the specimens ( 12 ), being detected by an optical device ( 19 ) and being fed as a sum of the light radiated from all the specimens ( 12 ) to at least one sensor ( 27 ) for intensity determination and analysis in an analyzer ( 32 ) following said sensor, the light sources ( 14 ) being driven individually by a control unit ( 31 ), the analyzer ( 32 ) as well as the control unit ( 31 ) being controlled such that the analyzer ( 32 ) determines the light from each specimen ( 12 ) separately from the light of other specimens, wherein the control unit ( 31 ) modulates the light sources ( 14 ) with different signals that are fed as specific defaults into the analyzer ( 32 ) to determine, from the summed signal received by the sensor ( 27 ), by means of said analyzer, the light signals altered by the individual specimens ( 12 ).
