Method for producing a stereo light pair for viewing in a stereo light viewer

摘要

The stereo photo-viewer has two windows (6a,6b) in which one stereo photo of a pair is mounted. The sizes of the two stereo photos including their black frames are at least as big as the windows including the mounting tolerance. The viewer is made of folded cardboard and is folded out from its folded-up state for storage in which a lens-holding front surface (1) rests against a rear surface (2) containing the windows and pair of stereo photos. Pressure is exerted on two opposite facing main folds (7,9) to fold out the viewer for use in which the front and rear surface face each other in a continuously adjustable focusing distance apart. The front and back surface are joined at the sides by foldable anti-glare surfaces (10a,10b).
