Rhomboid Prism
Rhomboid Prism
Rhombic custom prisms are used to displace a beam laterally without changing its direction. They may be coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. These rhombic prisms are manufactured from either BK7A or Fused Silica. They are supplied uncoated but many coating options are available.
