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