Each material window can display different representations of the optical constants.

In the following the computed quantities are demonstrated using a dielectric function for quartz glass in the mid infrared. It looks like this:

Use the Properties submenu to select the property which is to be displayed in the material's window. At present, the following properties (besides the dielectric function) can be computed and displayed:

•Refractive index

•Absorption coefficient

•Energy loss function

If you change the selection of the displayed property the graphics parameters are automatically changed and auto-scaled.
