Plate Beamsplitters
Plate Beamsplitters divide an incident, monochromatic
beam into reflected and transmitted
components with the specified intensity ratio. The
plate is coated on one side with a polarization
sensitive, partial reflection coating, and on the
reverse side with a high efficiency, narrowband,
anti-reflection coating.
