K9 aluminized dot beam splitter

  • For dielectric film beam splitter, the reflectivity of polarization component P is always lower than that of S component. This effect is more obvious in cubic beam splitter.
  • In applications requiring high polarization, metal coating beamsplitter should be selected.
  • The aluminized lattice beam splitter has a wide wavelength range and is insensitive to the incident angle. The beamsplitter coating is light in weight, moderate in price and relatively easy to make.
