Optical element having a toric surface and method of making
摘要:
An image forming system is described that includes a light source that provides a light beam and an anamorphic refractive optical element. A first outer surface of the anamorphic element faces the light source and includes a toric surface. The light beam is incident upon the first outer face and then an incident surface of the anamorphic element. The anamorphic element directs the light beam to an image forming device. An illumination system is also described where an anamorphic element includes a toric surface and a facet surface.
