Figure 1
Schematic of the grazing-angle optical setup viewed from above. The modulated beam from the interferometer is focused and collimated by parabolic and flat mirrors numbered in the order of the optical path as described in the text. The focus point between mirrors 1 and 2 allows optical elements such as polarizers, filters or iris to be inserted. The position of the sample holder is indicated by the letter S. The camera at the bottom allows for checking the visible-light spot on the sample. The gold evaporator is below the camera axis.
