发明名称 Counter-rotating anamorphic prism assembly with variable spacing
摘要 A counter-rotating anamorphic prism pair assembly with variable spacing allows the simultaneous adjustment of a prism pair using an adjustment member to circularize in cross section a range of elliptical laser beam cross sections. A first prism rotates and translates towards or away from an incident laser beam while a second prism simultaneously rotates towards or away from the laser beam in a fixed counter-rotating relationship with the first prism. The degree of rotation and translation is determined by a mechanical linkage connecting the two prisms.
