ABSTRACT:
Apparatus for producing a line source of a desired shape from a light source such as an excimer laser comprising means for directing the light source along a predetermined path to a cylindrical lens positioned to produce a virtual line image having uniform intensity along its length at a first location. However, the image is intercepted by a cylindrical mirror inclined at an angle so that the beam is transformed into a curved shape and directed onto a quartz diffuser. This apparatus produces a curved self-luminous distribution having uniform intensity over its length. In a specific embodiment, the diffuser is a directional diffuser.
