Rudolph Technology AutoEL IV Ellipsometer

The AutoEL IV is designed to provide precision film thickness measurements with simplicity of use. Internal data reduction software offers the convenience of automatically transforming delta and psi into the physical properties of thickness and refractive index. The system’s non-volatile memory allows users to retrieve previously determined sample parameters during future measurements, to speed repeated analyses of similar materials. The system's thermal printer can provide a hard copy of the results.
