Patent ID: 8139105

Claim:
Device for optically scanning a sample ( 1 ), having at least one adjustment unit ( 2 , 3 ), having a drive device ( 2 ) as well as a sample table ( 3 ), and having at least one scanning device ( 4 , 5 ), whereby a white-light source (W) is disposed underneath the sample table ( 3 ) and transilluminates the sample ( 1 ), so that the image of the sample ( 1 ) is recorded by the scanning device ( 4 , 5 ) disposed above it, whereby furthermore the sample ( 1 ) is moved relative to the scanning device ( 4 , 5 ), by means of the adjustment unit ( 2 , 3 ) activated by a control system ( 6 ), or vice versa, and whereby individual images of the sample ( 1 ) are taken, using the scanning device ( 4 , 5 ), and subsequent to this, combined to form a total image, in the control system ( 6 ), wherein correction values (K) are recorded and stored in the memory of the control system ( 6 ), and taken into consideration during the setting procedure, for equalization of mechanical insufficiencies of the adjustment unit ( 2 , 3 ) and/or the scanning device ( 4 , 5 ), using a mask ( 7 ) scanned in place of or in addition to the sample ( 1 ), having defined markings ( 9 ).
