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.
