Rhombic Prisms, also named Rhomoid Prisms, are used to display a beam laterally without changing it is direction. They maybe coated to transmit part of the beam and prodcue two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. Coating design are per customer¡¯s design according it is detailed application. |
