Optical arrangement for correcting an astigmatic image formation

Optical arrangement for correcting an astigmatic image formation

An astigmatism-correcting optics has, in addition to an astigmatism-correcting concave mirror (4) which is rotatable for adjustment, an adjusting mount (11) which is displaceable along the focal line (locus curve of the focus) which is defined by the focal points (8, 8', 8'') belongin...

Zusammenfassung:An astigmatism-correcting optics has, in addition to an astigmatism-correcting concave mirror (4) which is rotatable for adjustment, an adjusting mount (11) which is displaceable along the focal line (locus curve of the focus) which is defined by the focal points (8, 8', 8'') belonging to different adjusting positions of the astigmatism-correcting concave mirror (4). A collimating optics (13) and a deflecting optics (17) are rigidly connected to the adjusting mount (11).
