ABSTRACT:
An optical imaging apparatus, in particular an ophthalmoscope or microscope or transillumination microscope, comprising a light source arrangement (20) and an illumination beam path (3) which is predetermined at least by an illumination lens arrangement (4), and an observation beam path (11) which is predetermined at least by an observation lens arrangement (12), wherein at least one illumination field aperture (2) is arranged in the illumination beam path (3) and at least one observation field aperture (13) is arranged in the observation beam path (11) and the illumination beam path (3) and the observation beam path (11) are arranged at an angle different from 0° in an illumination image plane (6) in which the illumination field aperture (2) can be imaged by the illumination lens arrangement (4), wherein the illumination lens arrangement (4) and the observation lens arrangement (12) are lens arrangements which are separate from each other, wherein a single light-reflecting mirror body (14) which is oscillatingly reciprocatably pivotable about a pivot axis (15) is arranged in the illumination beam path (3) and in the observation beam path (11).
