摘要:
The present invention relates to a fundus camera which is one kind of diagnosis equipment used for a medical eye examination at an ophthalmic clinic. The multispectral coaxial non-mydriasis fundus camera using illumination sources of near-infrared rays and visible light of the present invention comprises: an illumination unit (10) configured to emit light; a diffusion lens (20) configured to diffuse the light introduced from the illumination unit (10); an illumination lens (30) configured to emit the light introduced from the diffusion lens (20) at a predetermined emitting angle; a mirror (40) configured to reflect the light introduced from the illumination lens (30); a polarized beam splitter (50) configured to transmit P-polarized light and reflect S-polarized light, from the light introduced from the mirror (40); an objective lens (60) configured to lighten a fundus with the light introduced from the polarized beam splitter (50) and enlarge an image of the fundus that is returned; a near distance ocular lens (70) configured to reduce or enlarge the image of the fundus enlarged by the objective lens (60); and an image pickup device (100) configured to obtain an optogram using the image of the fundus from the neaer distance ocular lens (70). The illumination unit (10) comprises: an illumination source of near-infrared rays (11) capable of emitting near-infrared rays; an illumination source of visible light (12) capable of emitting visible light; and a non-polarized beam splitter (13) configured to allow the near-infrared rays emitted from the illumination source of near-infrared rays (11) and the visible light emitted from the illumination source of visible light (12) to be coaxially emitted. According to the present invention, it is possible to remove various types of internal reflection, thereby obtaining a vivid optogram.본 발명은 안과 검진의 진단장비의 일종인 안저카메라에 관한 것으로서, 본 발명인 근적외선 조명원과 가시광선 조명원을 사용한 동축 비산동 다중 스펙트럼 안저카메라는: 광을 방출하는 조명부(10); 상기 조명부(10)에서 인입된 광을 확산하는 확산렌즈(20);
