Patent ID: 8072608

Claim:
An apparatus for the imaging and/or measuring of a measuring object ( 9 ) by means of interferometry in an interferometric imaging mode and by means of non-interferometric imaging in an optical imaging mode by recording a digital evaluation of optical images of the measuring object ( 9 ), comprising: an objective ( 8 ) for determining a beam path and for receiving light from the measuring object ( 9 ) and for supplying the received light to an image receiving device ( 12 ), the measuring object ( 9 ) is positioned in the same beam path along the optical axis of objective ( 8 ); a positioning unit ( 13 ) for adjusting the relative distance between the objective ( 8 ) and the measuring object ( 9 ) along the optical axis; a first beam divider ( 2 ) for determining together with a reflector ( 4 ) a reference light path ( 3 ), said beam divider ( 2 ) arranged in the beam path; a first illumination device ( 1 a ) for illuminating the measuring object ( 9 ) associated with the beam path so as to introduce light emitted from the first illumination device ( 1 a ) into the reference light path ( 3 ) and also into the beam path, the first illumination device ( 1 a ) is connected to the beam path at a location between the image receiving device ( 12 ) and the first beam divider ( 2 ) so that the first illumination device ( 1 a ) light passes through the beam divider ( 2 ) in two directions opposite to each other, and; a second illumination device ( 1 b ) for illuminating the measuring object ( 9 ) while the light thereof is kept away from the reference light path ( 3 ), the light of the second illumination device ( 1 b ) passes through the first beam divider ( 2 ) exclusively in a direction from the measuring object ( 9 ) toward the image receiving device ( 12 ).
