I've written many programs in IDL that you're welcome to use if you
like. Listed below is a short description of what's available. If
you're interested, have a look at
<http://www.bell-labs.com/user/windt/idl/> for complete
downloading and installation instructions.
Available IDL libraries:
imd - Multilayer optical properties: modeling and curve-fitting
Version 3.0, 17-September-1997
IMD is a point-and-click IDL application that can calculate the
optical properties - reflectance, transmittance, and absorptance
- of an arbitrary multilayer structure, i.e., a structure
consisting of any number of layers of any thickness, and of any
material. IMD includes a database of optical constants for over
150 materials, spanning the photon range from the X-ray region
to the far infrared. It's also easy to use your own optical
constants if necessary, or to create new X-ray optical constants
for any compound, using the CXRO tabulated atomic scattering
factors for 92 elements. IMD can be used for both modeling, and
for parameter estimation by non-linear, least-squares
curve-fitting (including confidence interval generation) to your
own measured data. IMD can also compute the electromagnetic
field intensity vs. depth in a multilayer structure.

topo - Surface topography analysis
Version 2.01, 14-August-1997
The topo library is a set of IDL routines for analyzing 1D or
2D surface topography (i.e., surface roughness) data. I
originally wrote these routines in order to analyze WYKO and
AFM data of optical surfaces, but the routines are general, and
can be used to analyze any type of 1D or 2D topography data.

windt - General purpose routines
last updated 10-September-1997
Lot's of different stuff here. Some of the highlights:
-LEGEND, CURVE_LABEL, and PLOT_TEXT: for robust plot annotation
-PLOT_PRINT: an easy-to-use graphical printer interface
-MORE and EROM: to easily write and read vectors to/from ASCII
files
-VALUE_TO_INDEX: given a scalar value, find the closest array
index
-DIALOG: like WIDGET_MESSAGE, but also includes fields and lists
-Several compound widgets for graphics
