SNF is open under New Normal Rules. ANY shadowing must be coordinated with SNF staff first.
The Nanometrics Nanospec system uses non-contact, spectro-reflectometry (measurement of the intensity of reflective light as a function of incident wavelength) to determine the thickness of transparent films (up to two) on substrates, such as silicon, that are reflective in the visible range. Wavelength range is from 300nm-900nm.
