Abstract: An illumination system includes optics capable of adjusting the size of a beam of light and adjusting the focus of the beam of light. Spot size control optics adjusts the overall size of the beam of light and separately adjusts the ellipticity of the beam, primarily in one dimension. Light from the spot size control optics passes to focus control optics that control the overall focus of the beam of light and adjust the astigmatism of the beam by altering the focus position of the beam of light in one dimension. The laser system, the spot size control optics and the focus control optics are within an enclosure. Actuators under remote control from outside of the enclosure adjust both of the spot size control optics and focus control optics in the thermal environment of the illumination system.
