Abstract:
A fixture used in fabricating one or more optical components, each having at least one optical element and a mounting surface, the fixture comprising one or more troughs defined on a first side of the fixture, each trough adapted to receive at least one of the one or more optical components, each trough having opposing shelves adapted to support the at least one of the one or more optical components, the shelves defining an aperture in each trough such that, when each optical component is placed within a trough, at least a portion of the mounting surface of said each optical component will be exposed when a plasma or ion beam is directed at said each optical component from a second side of the fixture, while the shelves shield the at least one optical element in said each optical component from direct exposure to the plasma or ion beam, wherein, for each trough:the shelves have side walls that are substantially mutually parallel and bases that are substantially mutually co-planar; andthe aperture is defined by aperture walls that are substantially mutually parallel and closer together than the side walls of the shelves.
