摘要: A partially-reflecting surface of a beam splitter is made dielectric reflecting coating which at large incident angles light quite sensitive to the direction polarization light. Thus two beams divided by and selectively directed common point, in parallel directions, etc., may be matched intensity placing half-wave plate entrant rotating same change alter proportion that transmitted and/or reflected splitter.
