Abstract
What is described here is a system for as well as a method of geometric beam shaping of the beam profile of a light beam, comprising a first prism and a second prism optically transparent to the light beam, which prisms are so disposed in the optical path of he light beam in such a way that after the passage of the light beam through both prisms the beam profile of the light beam may be expanded or reduced in a direction orthogonal on its direction of propagation by a first factor, and by a second factor different from the first factor in a direction orthogonal on the first direction. The invention excels itself by the provision that the first prism is supported for rotation about an axis of rotation and that the second prism is rotatable about a further axis of rotation and is supported for movement along a curve relative to the first prism.
