Scheme of the SNOM-setup showing the arrangement of the main components. The sample (a) is placed on a piezo-scanning stage (b) and scanned with a tuning fork SNOM probe (c). Through the SNOM tip (d) (zoom (e) showing the inner Au/Cr coating) the laser light coupled out of an optical fibre (f) is coming in contact with the sample and reflected back through an objective (g) and filter before the signal is detected with an APD.
