Spectroscopic Ellipsometer
IR-VASEĀ® - J.A. Woollam Co., Inc. (J. A. Woollam Co.)
The IR-VASE is the first and only spectroscopic ellipsometer to cover the spectral range from 2 to 30 microns (333 to 5000 wavenumbers). The IR-VASE can determine both n and k for materials over the entire width of the spectral range without extrapolating data outside the measured range, as with a Kramers-Kronig analysis.
