| 摘要 |
<p>The invention relates to an optical arrangement for ophthalmological devices for improving fundus images, especially for imaging the retina. Said arrangement comprises, accommodated in a housing, an optical illumination and imaging system with tilted and/or out-of-center, refractive and/or reflecting surfaces or arrangements of non-tilted or non-out-of-center optical surfaces having a black point design in the illumination system. An imaging optical system comprising at least one imaging mirror (11; 12) is provided in an imaging beam path. In order to compensate image defects of the imaging optical system, at least one reflecting, refractive, electronically structurable or adaptive optical element, e.g. a mirror (12) having adjustable, adaptive elements (12a), is provided in the beam path. The arrangement also has means for generating control signals for controlling the adaptive elements (12a) of the at least one optical element (12).</p> |
