Beamsplitter Plate

Beamsplitter Plate (Beamsplitter Plano-Flate) have low absorption and beam deviation. MHB can supply narrow band and Broadband wavelength beamsplitter plate. Dichroic plate beamsplitters can also be used as color combiners, in the red, blue and green spectrum. It is widely used in projection optics systems, imaging optics systems, optical measurement systems & optical display systems.
