Abstract
A parallel pencil of light, for example, a laser beam, is expanded by means of a cylindrical lens. The lens is fully cylindrical and has an optically thinner medium of cylindrical shape in its interior. The lens is arranged relative to the pencil of light so that total reflection occurs at the interface with the optically thinner medium.
