DTU intends to order an imaging spectroscopic nulling ellipsometer for anisotropic refractive index measurements on materials with sample sizes down to few micrometers. The equipment should have the ability to: • Measure…
the uniaxial anisotropic complex refractive index of samples with thickness of around 100 nm, and determine both the refractive index and thickness with high accuracy • Provide spatial resolution down to 1 micrometer (at a wavelength of 400 nm) for measuring few-micron-sized samples, such as exfoli
ated 2D materials. • Provide variable angle imaging spectroscopic ellipsometry (from 38° to 90°, where 90° means transmis-sion mode). • Measure over a spectral range covering 190 nm – 1000 nm (UV-Vis), with the capability of being upgraded
