Abstract

An arrangement for examination of one or more specimens arranged in specimen vessels or on specimen carriers by transmitted light or incident light by imaging and/or detecting at least a portion of the specimen volume through the specimen vessel or specimen carrier by a CCD camera followed by an evaluating unit, wherein, advantageously, an incident illumination is likewise effected through the specimen vessel or specimen carrier and the illumination is used to excite specimen emission, preferably fluorescence excitation.
