Claims

[Claims for Utility Model Registration] 1. An Albada-type inverted Galileo comprising a first objective lens, a second objective lens with a concave periphery as a reflecting mirror, and an eyepiece lens with a light frame, arranged in order of the field of view. In the finder, the concave surface near the center of the first objective lens is used as a translucent reflecting mirror, and a distance measuring frame is formed on the surface of the second objective lens, and the distance measuring frame illuminated by external light is connected to the first objective lens. Albada type reverse Galilean finder in which the light is reflected by the concave semi-transparent reflector of the objective lens, passes through the second objective lens and the eyepiece, and can be seen as a distance measurement light image frame together with the field image and field light image frame. . 2. The distance between the first objective lens and the second objective lens and the distance between the second objective lens and the eyepiece lens can be slightly displaced so that the diopter of the distance measurement light image frame and the field light image frame can be adjusted separately. An Albada type reverse Galileo finder as set forth in claim 1 of the patent registration claim. 3. The second objective lens and the eyepiece lens are each movable in a direction substantially perpendicular to the optical axis, and the variation of the range-finding light image frame and the field-of-field light image frame can be adjusted individually. The Albada type reverse Galileo finder described in item 1. 4. The second objective lens can be slightly displaced vertically and horizontally around the distance measuring frame.1. An Albada-type reverse Galilean finder according to claim 1 of the registered utility model, which is capable of correcting vararax of a distance-measuring light image frame.
