Abstract (en)

[origin: US7753522B2] The invention is directed to a method and a device for opthalmological equipment for examining the fundus of the eye by means of an optical system and electronic sensors for image recording. The focusing device, according to the invention, for opthalmological equipment based on the nonmydriatic principle comprises a projection unit which projects at least one focusing mark in the infrared spectral region on a surface in the eye and a focusing unit, both of which are displaceable along the optical axis. The displacement carried out by electronically controllable adjusting elements is carried out simultaneously or individually based on the corresponding presets of a control unit that is provided. The necessary synchronization between the projection unit and the focusing unit can be ensured in a simple manner by means of the inventive solution. Accordingly, not only can the sequence of displacement paths be optimally adapted over the entire focusing range, but the tolerances of the optics assemblies can also be compensated individually in a simple manner from one device to another.
