Abstract
An apparatus for splitting radiant energy beams produced by a laser or other light source. The apparatus comprises a plurality of mirrors, each aligned to reflect a beam or plurality of beams from one mirror to the next. Each mirror comprises a glass body with a layer of 50% reflective coating and a layer of anti-reflecting coating on one side of the body. A layer of 100% reflective coating is on the other side of the body. A beam is, thus, 50% reflected from the first reflective layer and allowed 50% to pass through the layer. The remainder of the beam is reflected from the 100% reflective layer.
