ABSTRACT:
Two single-refraction prisms which produce enlarged or reduced images in two dimensions. The prisms have cylindrical members which can be revolved so as to emit the refracted beams without additional refraction. The first prism enlarges the image in the vertical dimension, and the second prism enlarges the image in the horizontal dimension.
