Zusammenfassung:PCT No. PCT/DE90/00285 Sec. 371 Date Nov. 19, 1990 Sec. 102(e) Date Nov. 19, 1990 PCT Filed Apr. 12, 1990 PCT Pub. No. WO90/13054 PCT Pub. Date Nov. 1, 1990.An optical system for imaging the light from light sources having varying astigmatic differences of focus in different planes, having an optical element with an astigmatic effect and having an imaging lens system, the optical element having an astigmatic effect being provided with two lens components, the distance of which in the direction of the optical axis can be adjusted in order to correct astigmatic differences of focus varying from light source to light source and/or changing astigmatic differences of focus due to aging.
