An apparatus for the observation and treatment of the eye with a laser, having an illumination light source, whose light is focussed on the part of the eye to be observed and which preferably contains a laser, a scanning device, which generates a scanning movement of the light of the illumination light source on the background of the eye, a detector device, which receives the reflected light, an evaluation and synchronization unit, which generates from the time-sequential signal output of the detector device a visual representation of the portions of the eye to be treated and shows the visual representation, on a monitor, and a treatment laser device, whose light can be reflected on the part of the eye to be treated. The apparatus provides that a visual representation in which the location or locations to be treated are marked, can be superimposed on the visual representation of the eye at least on the monitor, and a control unit aligns the laser to the marked location.

Apparatus for the observation and the treatment of the eye using a laser

Disclosed is an apparatus for aligning a focused beam of light and, in particular, a laser beam onto a surface using optical elements which image, respectively shape, deflect and align the beam of light. The present invention is distinguished by a deflecting optical element having, in addition, a focusing effect.

Apparatus for aligning a focused beam of light

Disclosed is an apparatus for examining objects having an illumination light source, the light of which can be focussed on the part of the object to be examined, a scanning device, which generates a scanning movement of the light beam from the illumination light source over the section to be examined and which is provided with beam-deflecting and beam-imaging optical elements, a sensor device, which receives the light reflected from said section to be examined, and an evaluation and synchronization unit, which produces an image of said section to be examined from the time-sequential output signal from said sensor device. The invented apparatus is distinguished by the fact that the optical axis of the examination and/or illumination beam can be shifted in a plane of said pupils in order to generate a stereoscopic image, and that the images produced with varying positions of the optical axes can be overlapped in order to produce a stereo image.
