SNOM-Videos
With an optical nearfield spectroscope it is possible to make interesting animations by varying the detection wavelength. This page shows a number of photoluminescence measurements on optical semiconductors. All measurements are from the Institute of Applied Physics, Technical University Braunschweig. The basis of the SNOM set-up is a DME DualScope™ DS45-40 Scanner.
Every animation was made from the data of one single measurement. A click on the corresponding image will start the video.
