Plate Beam splitters
Plate beamsplitters are designed to be used at a 45° angle of incidence. Since they have a finite thickness (as much as 3 mm) the beam is slightly displaced as it passes through the plate.
Mainly used in Projection Optics System, Imaging Optics System, Optical Measurement Systems, Optical Display Systems.
