N-Layer Plane Wave Reflectance vs thickness of any layer
(Copyright M. Gallant 1996, 2001)

*** Java enabled browsers would see a computation applet here***
(graphic of applet shown below).


This page presents a Java applet for calculating the optical thin film reflectance of a multi-layer coating as a function of the thickness of any one of the layers. At present, the number of layers is fixed at 5. The polarization type can be toggled with the TE/TM button. The parameters can be changed in the textfields. Activating the CALCULATE button recalculates and replots on the grid. Note that mouseDown anywhere in the plot field displays the HORIZONTAL coordinate in the X/Y data window, while mouseUp displays the VERTICAL coordinate. The fast computation routine is based on Rouard's method.
