2 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Stereoscope \Ste"re*o*scope\, n. [Stereo- + -scope.] An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer. Note: In the reflecting stereoscope, the rays from the two pictures are turned into the proper direction for stereoscopic vision by two plane mirrors set at an angle with each other and between the pictures. In the lenticular stereoscope, the form in general use the eyeglasses are semilenses or marginal portions of the same convex lenses, set with their edges toward each other so that they deflect the rays coming from the picture so as to strike the eyes as if coming direct from an intermediate point, where the two pictures are seen apparently as one From WordNet r 1.6 [wn]: stereoscope n : an optical device for viewing stereoscopic photographs
