    • A focusing unit (11) is constituted of a prism base (11a), deflection prisms (11b and 11c), and a slit chart (11e) having a slit opening (11d), and the deflection prisms (11b and 11c) are arranged so that deflecting directions may become reverse. The slit opening (11d) is made equally to spread across the deflection prisms (11b and 11c) approximately and is impermeable except the slit opening (11d), and light incident on the deflection prisms (11b and 11c) passes only this slit opening (11d). In addition, the light which is emitted by a focus index illumination light source illuminates the slit opening (11d) through the deflection prisms (11b and 11c). As to an image of the illuminated slit opening (11d), two slit images are formed on a fundus of eye by actions of the deflection prisms 11b and 11c. Focus adjustment is made by aligning these slit images (S1 and S2) in a straight line.
    • 聚焦单元(11)由棱镜基座(11a),偏转棱镜(11b和11c)以及具有狭缝开口(11d)的狭缝图(11e)和偏转棱镜(11d)构成 b和11c)被布置成使得偏转方向可能变得相反。 除了狭缝开口(11d)之外,狭缝开口(11d)大致平均地扩展横跨偏转棱镜(11b和11c),并且不透水,并且入射到偏转棱镜(11b和11c)上的光, 仅通过该狭缝开口(11d)。 此外,由聚焦折射照明光源发射的光通过偏转棱镜(11b和11c)照射狭缝开口(11d)。 对于照明狭缝开口(11d)的图像,通过偏转棱镜11b和11c的作用在眼底形成两个狭缝图像。 通过将这些狭缝图像(S 1和S 2)对齐在直线上进行对焦调整。

    • An ophthalmologic apparatus includes a diaphragm, a photo taking system, having a mirror system with a deflection mirror, for taking an eye fundus through the mirror which is disposed in a position nearer to an eye to be examined than to the diaphragm on an optical path, and a controller. The controller controls the photo taking optical system so as to perform photo taking plural times by changing directions of the mirrors, so that a plurality of images for the eye fundus are obtained from a plurality of directions.
    • 一种眼科装置,包括一个隔膜,一个摄影系统,具有一个带有偏转镜的镜子系统,用于通过一个镜子将眼底放置在镜子上,该镜子设置在一个更靠近被检眼的位置上,而不是光路上的隔膜 ,和控制器。 控制器控制摄影光学系统,以通过改变反射镜的方向进行多次拍摄,从而从多个方向获得用于眼底的多个图像。
