Abstract
The invention relates to an image reversion system (500) which enables an image reversion and beam transposition of a plurality of observation beam paths (503a, 503b, 504a and 504b) to be carried out simultaneously. The system includes at least one Porro prism system and is designed in such a way that it can be arranged in a convergent beam path. The inventive system is suitable as an image reversion system in an ancillary module for operational microscopes used in ophthalmoscopy due to the low overall height thereof.
Claims32
A system for image reversion for operating on a beam, the system comprising:
- a first 90° prism having a base surface defining a first mirror for receiving said beam thereon in an incident direction and deflecting said beam in a first direction transverse to said incident direction;
- a second 90° prism having a base surface defining a second mirror for deflecting said beam reflected from said first mirror into a second direction transverse to said first direction;
- a half Porro prism having a first surface defining a third mirror for deflecting said beam reflected from said second mirror into a third direction transverse to said second direction;
- said half Porro prism having a second surface defining a fourth mirror for deflecting said beam reflected from said third mirror into a fourth direction transverse to said third direction;
- said first, second, third and fourth mirrors having first, second, third and fourth surface normals, respectively;
- said surface normals being at an angle to each other;
- and,
- said second 90° prism being rotatable about an axis running transversely to said second surface normal so that a tilting of a surface of said second 90° prism can be adjusted to an opposite-lying surface of said first 90° prism.
