Abstract
A portable ophthalmic apparatus (1) according to the present invention comprises a supporting part (7) to which a cellular phone (2) having a photographing camera (5) is mounted detachably and a main body (6) which is provided with the supporting part (7) integrally and has an illumination optical system (13) projecting an illumination beam toward photographing objective eyes (E) along an illumination optical axis (O2) intersected at a predetermined angle with a photographing optical axis (O1).
Claims17
A portable ophthalmic apparatus comprising:
- a supporting part which attaches detachably to a portable device having a photographing camera part on a photographing optical axis;
- and
- a main body which is arranged integrally with said supporting part and which comprises an illumination optical system for radiating an illumination beam toward photographing objective eyes along an illumination optical axis intersected at a predetermined angle with said photographing optical axis,
- wherein said illumination optical system comprises a slit opening stop and wherein, by projecting a slit illumination beam toward said photographing objective eyes, sectional shapes of a cornea and a crystal lens are photographed.
