Facts

The Woollam Vase is an ellipsometer with variable wavelength and angle of incidence. It is capable of

  • Reflection and Transmission Ellipsometry
  • Generalized Ellipsometry
  • Reflectance (R) intensity
  • Transmittance (T) intensity
  • Cross-polarized R/T
  • Depolarization
  • Scatterometry
  • Mueller-matrix

Its incident wavelength range is 200nm up to 2500nm (with different cable)

Tool & Process Information

The Woollam VASE (Variable Angle Spectroscopic Ellipsometer) may be used to characterize thin films on a variety of substrates.

  • The HS-190 monochromater has a spectral range of 240-1700nm.

The system has two fiber optic cables.  See a staff member for change and alignment.

  • UV150-2.0M Range 240-1700nm (except 1350-1420nm)
  • IR150-2.0M Range 270-1700nm

Transparent substrates should have the backside roughened or blackened to reduce reflections.
