Inorganic waveplate

Inorganic waveplate that enables higher contrast in high-end projectors.

  • Product name
    Inorganic waveplate (1/4, 1/2, etc.)
  • Features
    • The precision thin-film laminating technology enables realization of high transmittance and wavelength conversion efficiency.
    • Our unique nano-level inorganic thin-film structuring enables realization of high thermal resistance, light resistance and durability.
    • Inorganic waveplate offers greater slimness than crystal types (product thickness: 0.3 mm or less) and features a maximum size of 100 mm square.
    • Lineup of 1/4 waveplate, 1/2 waveplate and achromatic 1/2 waveplate for wide bands. Possible to customize a specification as your request.
