System Information

General Description

The cleanroom Ellipsometer can measure the thickness and refractive index of thin films on reflective substrates, as well as the optical properties of bare substrates.


  • The stage can handle up to a 6 inch wafer diameter
  • The ellipsometer utilizes a single laser at a wavelength of 6328Å
  • Film Thickness Range: 0-60,000 Angstroms
  • Spot size is approximately 1mm by 3mm
  • Your substrate must be polished and must not rough to defract the laser

Materials Compatibility

Not Applicable


Please know the optical constants (refractive index and extinction coefficient) of both your film to be measure, and the substrate you are measuring upon.
