发明名称 View finder
摘要 An inverse Galilean view finder has an object lens and an eyepiece lens. The front of the object lens is flat surface. First micro corner cube prisms are arranged in a frame of visual field around the external periphery of the flat surface. Second micro corner cube prisms are arranged in a frame on the rear surface of the eyepiece lens. Light from an object is reflected toward the object lens by the second micro corner cube prisms. Reflective light from the second micro corner cube prisms is reflected by the first micro corner cube prisms, and returns to the eyepiece lens. The reflective light of the first micro corner cube prisms brights and it is observed within a finder as a finder field frame indicating a range of photography.
