Standard plate beamsplitters split incident light by a specified ratio that is independent of the light's wavelength or polarization state, while polarizing plate beamsplitters are designed to treat S and P polarization states differently. Our plate beamsplitters have a coated front surface that determines the beam splitting ratio while the back surface is wedged and AR coated in order to minimize ghosting and interference effects. The Wedged Beamsplitter Plate offered below is designed to make multiple attenuated copies of a single input beam.
