Abstract
Abstract The optical system consists of a converging lens (L) at an adjustable distance (d) in front of two objectives (O1, O2) having an optic axis (XX) parallel to the optic axes (X1X1, X2X2) of objectives and at equal distances ( l /4) from the axes of the objectives. The monoscopic images (I1, I2) of a stereoscopic pair are located in the focal plane of the objectives and are preferably juxtaposed in a standard slide frame. The casing (T1, T2) of the optical system is mounted in a standard slide projector. <IMAGE>
