Multiple order

  • Waveplates-Multiple-and-Dual

    Multiple order waveplates (for two wavelengths)

    The multiple order waveplates comprise a single plate made from laser grade crystalline quartz. They are AR-coated on both sides and are available unfitted or fitted in an anodised aluminium ring. The standard retardances are λ/4 and λ/2; additional values are available on request.
      • Standard wavelength range 237 nm to 2021 nm (more on request)
      • Free aperture of 8, 10, 15, 23, 34 and 46 mm
      • In retaining ring or without retaining ring
      • 1/2λ and 1/4λ retardance
      • AR-coated on both sides
      • Material: crystalline quartz – laser grade
    • Thickness 0.3 to 1.3 mm
      Wave front deformation λ/10 @ 632.8 mm
      Surface quality 10/5 scratch/dig
      Parallelism 0.5 seconds
      Retardance tolerance ± 0.005 λ @ 632.8 nm
      Coating Antireflective, R < 0.25% per surface
      Damage threshold 1 kW/cm2 – CW, 3.5 J/cm2 @ 10 ns
      Diameter 10, 12.5, 17.5, 25.4, 38.1 and 50.8 mm, +0.00/-0.25 mm with or without appropriately sized retaining ring
      Thickness in retaining ring dependent on the diameter of the retaining ring
