Plate Beamsplitter can change the direction of the light path and can split input light into two separate parts. The construction of Beamsplitter is simple。The beamsplitter absorbs little light.It can loss a little light after splitting. The beam splitter curve graph is flat. And AR side has wedge and no ghosting. Beamsplitters are ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation or Microscopic imaging, machine vision.
