The STM images show both the larger corrugations and terraces existing on the surface, which would not be observed by SEM.

Based on a plane grating monochrometer and a optical scanner, the high time-resolved optical multichannel spectrometer is developed. A computer is used to real-time control and data acquisition.

The automatic system of measurement of the refractive index & thickness of NMSTF applies the reflection method to measure the parameters with the helium-neon laser as the incident light source.
