Cycloidal Diffractive Waveplate (CDW) Technology

  • Functional layers: Liquid crystal or liquid crystal polymer films
  • Film thickness: 1-5 µm
  • Deflection Angle: up to 15 degrees for single CDW layer
  • Polarization switching contrast: 800
  • Wavelengths: UV-LWIR
  • Diffraction efficiency: >95% (circular polarized light)
  • Bandwidth: 50-400 nm
  • Absorption losses per stage: <2% (Vis –NIR-SWIR), <4% (UV, MWIR)
  • Wavefront error in diffracted beam: λ/4 (@633 nm)
  • Substrates: All major transparent materials, including plastic
  • Substrate thickness: 5 μm (plastic sheet) – 5 mm (high degree polished optical windows)
  • Clear aperture: >90%
