NIR-UV spectroscopic ellipsometer J. A. Woollam V-VASE (WOOLLAM-VIS)

Description:

The VASE is most accurate and versatile ellipsometer for research on all types of materials: semiconductors, dielectrics, polymers, metals, multi-layers, and more. It combines high accuracy and precision with a wide spectral range from 193 to 2000nm. Variable wavelength and angle of incidence allow flexible measurement capabilities, absolute transmissivity and light scattering can be also measured.
