Abstract
A lateral transfer system for an optical beam comprises bipentaprisms (10) and (11) secured to opposite ends of an elongate transfer structure (12). The bipentaprism (10) comprises optical elements (20) and (21) positioned with respect to each other to form an empty pentaprism, and optical elements (22) and (23) positioned with respect to each other to form an empty roof-pentaprism. Similarly, the bipentaprism (11) comprises optical elements (30) and (31) positioned with respect to each other to form an empty pentaprism, and optical elements (32) and (33) positioned with respect to each other to form an empty roof-pentaprism. The optical elements (22) and (32) are beam splitters, while the other optical elements are reflectors. The bipentaprisms (10) and (11) are positioned with respect to each other so that an input beam impinging upon reflecting element (20) of the bipentaprism (10) is reflected to the beam splitter (22), where the input beam is split into a transmitted component and a reflected component. The transmitted and reflected components travel on different paths through the transfer structure (12) to the bipentaprism (11), and emerge therefrom as a pair of output beams. The average direction of the two output beams is precisely referenced in angle to the input beam.
