Glass Substrate

1. Measure a spectrum of the blank glass substrate by the spectroscopic scan.

• In this case, choose "open Exp.File" from the drop-down menu of File on Experimental Data window.

• For example, choose D2-1 glass_sub.dat from the files.

• Data is shown on Experimental Data and Graph windows.

2. Activate the Model window, and choose "Addlayer" from the menu or the drop-down menu shown by right-click of mouse.

3. Load "CAUCHY.MAT' file from Default Materials (or type "CAUCHY.MAT").

4. The following window appears.
