Patent ID: 7686450

Claim:
A device for measuring imaging errors in a human eye, comprising: a laser diode emitting a scanning beam to the eye in an area-wide fashion, and reflecting beams reflected from the eye being measured and evaluated; and a treatment laser emitting a treatment laser for treating a surgical correction of a cornea and/or lens and/or a retina of the eye wherein positioned in a scanning and/or reflecting beam path, and a treating beam path is a first beam splitter, wherein inserted as a tilting mirror into the scanning beam path, between the laser diode and the first beam splitter, a 2D microscanner mirror, with aid of which the scanning beam is deflected in two dimensions for area-wide scanning of the optical system of the eve with frequencies from 150 Hz to 32 kHz, and wherein inserted into the scanning beam path, between the laser diode and the tilting mirror, is a first electrically controllable liquid lens with the aid of which a divergence and a diameter of the scanning beam is set.
