Thin Film Calculator

Description:

Allows user to make Fabry-Perot reflection and transmission of thin film stacks. Plots both the s and p polarization curves and the phases. It can also plot either the amplitude or the intensity. It can take a very large stack of different layers with no limit.

Getting Started:

The Thin Film Calculator is accessed through the Accessories menu under the name ‘TFT Calculator” or from the Custom Pattern Panel.

Notes:

the opening screen is always set to the commonly used values
on the layer manager screen, click OK to save the layers used
an error message appears if there are no layers in the manager
the layer manager in this calculator works the same way as the thin film target layer manager

Parameters:

Index of Incident Medium: this is the index of the starting location
Index of Substrate: this is the last index in the stack
Wavelength: wavelength of the light in meters
From angle ___ to ___ : the chosen range of angles to make the plots, in degrees

Buttons:

Plot the amplitude: press this button to just graph the amplitude of reflection or transmission
Plot the intensity: press this to plot the intensity instead, (amplitude squared)
Save Plot Values: check this box to save the actual numbers used to make the plot. They are saved as a .mat file that can be opened in the Matlab workspace window
Reflection Plot: Chooses to plot the reflection curves
Transmission Plot: Chooses to plot the transmission curves
Change Layers: Opens the layer manager window
