DEVICE FOR IMAGING SAMPLE

摘要

An apparatus for imaging a sample arranged in a first medium in an object plane. The apparatus includes an optical transmission system which images the sample in the object plane in an intermediate image in an intermediate image plane. The object plane and the intermediate image plane form an angle not equal to 90° with an optical axis of the transmission system. The apparatus further comprises an optical imaging system having an objective. The object plane may be imaged on a detector without distortion. The optical transmission system is symmetrical with respect to a pupil plane, the object plane, and the intermediate image plane to satisfy the Scheimpflug condition. The intermediate image lies in a second medium having a refractive index virtually identical to that of the first medium. A lens group of a subsystem arranged closest to the sample or intermediate image comprises at least one catadioptric assembly.

1: An apparatus for imaging a sample arranged in a first medium in an object plane, said apparatus comprising:
an optical transmission system which comprises two subsystems constructed telecentrically, and which images the sample in the object plane in an intermediate image in an intermediate image plane, wherein the object plane and the intermediate image plane form an angle not equal to 90° with an optical axis of the transmission system; and an optical imaging system comprising an objective with an optical axis that is perpendicular to the intermediate image plane, the objective being focused on the intermediate image plane so as to image the object plane on a detector without distortion; wherein the two subsystems of the optical transmission system comprise a plurality of lenses; wherein the optical transmission system is constructed symmetrically with respect to a symmetry plane from the two subsystems so that the imaging is carried out by the optical transmission system on a scale of 1:1; wherein the optical transmission system is also constructed symmetrically with respect to a pupil plane, the object plane, and the intermediate image plane to satisfy a Scheimpflug condition; wherein the intermediate image lies in a second medium which has a refractive index that is virtually identical to that of the first medium; and wherein a lens group, of the plurality of lenses of the two subsystems, which is arranged closest to the sample or intermediate image comprises at least one catadioptric assembly.
