    • An optical element assembly includes a first optical element, a second optical element, and a positioning holder member. The first optical element has engageably shaped portions in a peripheral portion of an effective area on a first injection surface through which the effective luminous flux passes. These engageably shaped portions respectively correspond to one engageably shaped portions formed on one opponent surface of the positioning holder member that opposes the first injection surface. The second optical element has engageably shaped portions in a peripheral portion of an effective area on a second incident surface through which the effective luminous flux passes. These engageably shaped portions respectively correspond to the other engageably shaped portions formed on the other opponent surface of the positioning holder member that opposes the second incident surface. The positioning holder member has in a predetermined portion, an optical diaphragm aperture that permits transmission of light between the one opponent surface and the other opponent surface. An image pickup apparatus includes the optical element assembly, an image pickup device, and an image data producing portion.
    • 光学元件组件包括第一光学元件,第二光学元件和定位保持器元件。 第一光学元件在有效光束通过的第一注入表面的有效区域的周边部分中具有可啮合的成形部分。 这些可啮合形状的部分分别对应于形成在与第一注射表面相对的定位保持器构件的一个对手表面上的一个可接合形状的部分。 第二光学元件在有效光通量通过的第二入射面上的有效区域的周边部分具有可啮合的成形部分。 这些可啮合形状的部分分别对应于形成在与第二入射表面相对的定位保持器构件的另一对置表面上的其它可接合形状的部分。 定位保持器构件具有预定部分,允许光在一个对象表面和另一个对手表面之间传播的光学光阑孔。 图像拾取装置包括光学元件组件,图像拾取装置和图像数据产生部分。

    • An apparatus for measuring the refractive power of an eye has a target projecting system for projecting a target light beam onto the fundus of an eye to be examined through a predetermined region of the pupil of the eye to be examined, and a light-receiving optical system for receiving a light beam reflected by the eye fundus in at least three meridian directions through a region of the pupil of the eye to be examined different from the predetermined region. The light-receiving optical system includes a plurality of image rotating prisms for converting into a predetermined direction the direction of displacement to each meridian direction of the light beam reflected by the eye fundus produced by the difference in the refractive power of the eye to be examined. A light detecting device has a direction of light detection coincident with the predetermined direction and detects the light-position of the light beam reflected by the eye fundus which depends on the refractive power of the eye to be examined.
    • 用于测量眼睛的屈光力的装置具有目标投影系统,用于将目标光束投射到待检查的眼睛的眼底上,并通过待检眼睛的瞳孔的预定区域和光接收光 系统,用于接收通过眼睛的瞳孔的至少三个子午线方向反射的眼睛光束与不同于预定区域的被检眼的区域。 光接收光学系统包括多个图像旋转棱镜,用于将由被检眼的屈光度的差异产生的眼眼反射的光束的每个子午线方向的位移方向转换成预定方向 。 光检测装置具有与预定方向一致的光检测方向,并且检测由眼底反射的光束的光位置,其取决于待检查的眼睛的屈光度。
