Window assembly for use in substrate processing systems

Abstract

Embodiments of a window assembly are provided herein. In some embodiments, a window assembly for use in a substrate processing system comprising a first window at least partially transparent to light energy; a second window transparent to light energy and substantially parallel to the first window; and a separator disposed proximate the peripheral edges of the first and second windows and defining a sealed gap between the first and second windows, wherein the separator has an inlet and outlet to flow a gas through the sealed gap. In some embodiments, one or more support elements are disposed in the sealed gap to maintain a substantially uniform gap distance between the first and second windows. In some embodiments, a plurality of light adjusting elements are disposed in the gap to adjust one or more properties of light energy that passes through the light adjusting element.
