Abstract

A binocular indirect ophthalmoscope has illumination optics which have a tilted mirror that can be substantially-linearly displaced, by use of a first control, perpendicular to a beam path of an illumination beam exiting the ophthalmoscope, and that can be independently pivoted, by use of a second control, about an axis perpendicular to the beam path of the illumination beam and perpendicular to a direction of linear displacement, the mirror directing light of the illumination beam onto a retina of a patient. First and second controls for linearly moving and pivoting a tilted mirror are coupled to each other in such a way that the second control can be held at a fixed position relative to a housing of an ophthalmoscope.
