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.

摘要： An inverted Galilean finder is composed of an objective lens of a negative power and an eyepiece of a positive power, which are formed from a polystyrene resin by injection molding. The objective lens has a concave surface oriented to the eyepiece, and the eyepiece has a convex surface oriented to the objective lens. The inverted Galilean finder satisfies the following conditions: null0.75nullf1/f2nullnull0.60 f1nullnull22 null3.2nullf1/dnullnull1.5 wherein f1 is a focal length of the objective lens, f2 is a focal length of the eyepiece, and nulldnull is an on-axis surface distance between the concave surface of the objective lens and the convex surface of the eyepiece. The inverted Galilean finder of the present invention provides a magnification of about 0.6 to 0.8.
