Abstract
An adjustable beam splitter includes a pentaprism type reflector unit including a housing, a splitter mirror positioned in the housing for transmitting a portion of an input energy beam and for reflecting a portion of the input energy beam, and a reflective mirror mounted within the housing for directing the reflected portion of the input energy beam at a fixed angle to the input energy beam regardless of the angle of incidence of the input energy beam to the splitter mirror and regardless of manufacturing tolerances of the splitter mirror. Translation of the reflected portion of the input energy beam is reduced and the split ratio adjusted by rotating the pentaprism type unit about a line corresponding to the intersection of a plane containing the splitter mirror and a plane containing the reflective mirror.
