Abstract
An optical lens has a first plano-convex lens and a second plano-convex lens, with the planar sides of the two lenses opposite one another and the optical axes of the two lenses offset from one another. The offset allows a non-vertical light beam to enter and exit the lens at a 90° angle with respect to the two convex surfaces of the lens.
