Gaertner Scientific Two Angle Two Wave Stokes Ellipsometer LSE-2A2W
Automatically measures with both a red laser at 70° and green laser at 60° incidence angle. The 2 angle 2 wave capability determines thicker film thickness and gives refractive index measurements over a wider thickness range. Helps with difficult to measure films. Get many of the advantages of spectroscopic ellipsometers without the complexity.
