Abstract
27,644. Aragao, L. A. T. de. Dec. 14. Lenses; stereoscopes.-Stereoscopic images are produced in superposition and relief at g, or stereoscopic views are projected by a system consisting of two lenses a receiving separate pencils of rays 1,2, a reflecting system of prisms d, e, and a lens f, as shown. The prisms may be rotatably mounted to allow for adjustment. Diaphragms h with circular or annular apertures enabling particular portions only of the pencils to be utilized, are placed between the prisms d, e, and it is stated that a diaphragm with apertures such as p, Fig. 5, gives the same effect as the system if used with a single lens.
