The Rolleimeter (is not an exposure meter but a rangefinder focusing aid) uses the superimposed image principle and is actuated by and coupled to the moving front panel of the camera. It is attached to the nameplate directly in front of the direct view finder. A vertical glass rod with focusing spot for the two images can be seen when looking through the finder. Focusing the camera by superimposing the two images so that the outlines exactly coincide insures sharp focus. Framing and focusing are accomplished while looking through the finder, without making the eye strain one position to another.
