Achromatic Quarter and Half waveplate

Achromatic Quarter and Half waveplate (APAW)

Key Features:

  • Less sensitive to wavelength and temperature change than achromatic and super-achromatic quartz-MgF₂ waveplates;
  • Better angular acceptance than achromatic and super-achromatic quartz-MgF₂ waveplates;
  • Small beam deviation (less than 5 arcsec);
  • Absence of multibeam interference in transmittance;
  • Large set of wavelength range;
  • Large set of clear apertures (up to 70 mm);
  • Individual approach to each order, allowing you to optimize the quality and price of the plate;
  • Best prices.
