Abstract
In a method for correcting for the size and/or shape of a measuring volume (18)in a chemical and/or biological sample (14), especially in fluorescence spectroscopy, a measuring volume (18) located within the sample (14) is imaged to a detector means (44), using observing optics (32). The imaging is effected through a sample carrier w all (16) of a sample carrier (12) containing the sample (14). In the next step, the thickness of the sample carrier wall (16) is automatically determined. Thereafter, at least one lens (28) is shifted automatically along an optical axis of the observing optics (32) to correct for the size and/or shape of the measuring volume (18) as a function of the thickness of the sample carrier wall (16).
