| 发明名称 | Ophthalmoscope for observing an eye | ||
| 摘要 | An ophthalmoscope for observing an eye comprises a converging first lens system for generating a real intermediate image of a region in the eye in an intermediate image plane as well as an observation apparatus having an imaging optics for imaging the real intermediate image in an imaging plane in the observation apparatus and for imaging an aperture of the observation apparatus in a pupil of the eye. Between the first lens system and the imaging optics of the observation apparatus, a diverging second lens system is provided for enlarging a working distance between the first lens system and the pupil and for enlarging a field angle. | ||

| 主权项 | 1. An ophthalmoscope for observing an eye, the ophthalmoscope comprising a converging first lens system configured to generate a real intermediate image of a region in the eye in an intermediate image plane; an observation apparatus having imaging optics configured to image the real intermediate image in an imaging plane in the observation apparatus and configured to image an aperture of the observation apparatus in a pupil of the eye; and a diverging second lens system between the first lens system and the imaging optics of the observation apparatus, the diverging second lens system configured to enlarge a working distance between the first lens system and the pupil and/or to enlarge a field angle. | ||
