Abstract
An angular attachment has a housing (1) for fixing to an eyepiece (15) of a rangefinder camera (21) with laterally correct and height-correct representation of the finder image at an altered eyepiece angle, which contains a Bauernfeind prism (5) with double reflection in one plane as an image deflection element, a first region (A, A') of a base area (4) of the Bauernfeind prism (5) is disposed downstream of the eyepiece finder (15), an area opposite to this region is formed as a reflective area (8) and is inclined with respect to the base area (4) in such a way that a ray (2) entering the first region perpendicularly is reflected onto a second region (B, B') of the base area (4) at an angle of total reflection, and a light exit area (10) of the Bauernfeind prism (5) is inclined relative to the base area (4) in such a way that the totally reflected ray (9) impinges perpendicularly on the light exit area (10).
