2. Switch to the Scan tab by clicking the button in the Main Operations

panel to activate scanning-by-sample. Open the scanning parameters window by

clicking the

button. Select the following detection signals for the forward

pass:

- for ADC#1 – PMT;

- for ADC#2 – Height.

3. Perform scanning-by-sample of the selected area. The optical intensity distribution

and the surface landscape will be acquired (Fig. 4-19). For the example, the test

structure Al-projection pattern 0.453 µm on the cover glass (produced by Kentax.de)

was used. Images are presented with a color scheme that displays more transparent

regions with darker colors.
