Widest spectral range ellipsometer VASE
From Woollam Co.The VASE is our most accurate and versatile ellipsometer for research on all types of materials: semiconductors, dielectrics, polymers, metals, multi-layers and more.
- Ex-situ spectroscopic ellipsometer
- Wide spectral range from 193 to 4000 nm
- Maximum data accuracy
- High spectral resolution and perfect R&D flexibility
Further information
It combines high accuracy and precision with a wide spectral range from 193 to 4000 nm. Variable wavelength and angle of incidence allow flexible measurement capabilities including:
- Reflection and transmission ellipsometry
- Generalized ellipsometry
- Reflectance (R) intensity
- Transmittance (T) intensity
- Cross-polarized R/T
- Depolarization
- Scatterometry
- Mueller matrix
Maximum data accuracy
The VASE features a rotating analyzer ellipsometer (RAE) combined with our patented AutoRetarder for unparalleled data accuracy.
High-precision wavelength selection
The HS-190TM scanning monochromator is designed specifically for spectroscopic ellipsometry. It optimizes speed, wavelength accuracy, and light throughput, while automatically controlling selection of wavelengths and spectral resolution.
Flexible measurements
The VASE features a vertical sample mount to accommodate a large variety of measurement geometries including reflection, transmission, and scattering.
