An apparatus for producing an image of an object and, in particular, for examining the eye, having an illumination light source, the light of which can be focussed onto the section of the object to be examined, a scanning device, which generates a scanning movement of the source of the illumination light over the section to be examined and which is provided with beam-deflecting and image-forming optical elements, a detector device, which receives the light reflected from the section to be examined, and an evaluation and sychronization unit, which produces an image of the selected structures of the object from the time-sequential output signal from the detector device at least two image forming optical elements, which can be interchanged in order to alter the horizontal deflection angle, or image magnification in the horizontal direction, are provided in the beam path between the beam-deflecting elements.
A scanning ophthalmoscope apparatus for producing an image of an object and, in particular, for examining the eye, having an illumination light source, the light of which can be focussed onto the section of the object to be examined, a scanning device, which generates a scanning movement of the source of the illumination light over the section to be examined and which is provided with beam-deflecting and image-forming optical elements, a detector device, which receives the light reflected from the section to be examined, and an evaluation and synchronization unit, which produces an image of the selected structures of the object from the time-sequential output signal from said detector device, wherein an arrangement of at least two image-forming optical elements is provided in the beam path between said beam-deflecting elements, said arrangement of said at least two imaging-forming optical elements being interchangeable for varying image magnification in a horizontal direction, and said beam deflecting elements include a vertical deflecting device for being triggered for varying vertical image magnification in a vertical direction.
