    • A digital camera that combines the functions of the retinal camera and corneal camera into one, single, small, easy to use instrument. The single camera can acquire digital images of a retinal region of an eye, and digital images of a corneal region of the eye. The camera includes a first combination of optical elements for making said retinal digital images, and a second combination of optical elements for making said corneal digital images. A portion of these elements are shared elements including a first objective element of an objective lens combination, a digital image sensor and at least one eyepiece for viewing either the retina or the cornea. The retinal combination also includes a first changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said retinal region at or approximately at a common image plane. The retinal combination also includes a retinal illuminating light source, an aperture within said frame and positioned within said first combination to form an effective retinal aperture located at or approximately at the lens of the eye defining an effective retinal aperture position, an infrared camera for determining eye position, and an aperture adjustment mechanism for adjusting the effective retinal aperture based on position signals from said infrared camera. The cornea combination of elements includes a second changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said cornea region at or approximately at a common image plane.
    • 数码相机将视网膜摄像机和角膜摄像机的功能组合成一个,单个,小型,易于使用的仪器。 单个相机可以获取眼睛的视网膜区域的数字图像和眼睛的角膜区域的数字图像。 相机包括用于制造所述视网膜数字图像的光学元件的第一组合以及用于制造所述角膜数字图像的光学元件的第二组合。 这些元件的一部分是包括物镜组合的第一目标元件,数字图像传感器和用于观察视网膜或角膜的至少一个目镜的共享元件。 视网膜组合还包括所述物镜系统的第一可变元件,用于与所述第一目标元件结合,在或在其共同的图像平面处聚焦所述视网膜区域的一部分或全部。 视网膜组合还包括视网膜照明光源,所述框架内的孔,并定位在所述第一组合内,以形成位于眼睛的眼睛或近似位于眼睛的镜片处的有效视网膜孔,限定有效的视网膜孔位置,用于确定的红外照相机 眼睛位置和用于根据来自所述红外摄像机的位置信号调节有效视网膜孔径的光圈调节机构。 元件的角膜组合包括所述物镜系统的第二可变元件,用于与所述第一物镜组合在一起或近似于共同的图像平面处聚焦所述角膜区域的一部分或全部。
