Hi All,
It is with great pleasure that I announce the release of OpenFilters
version 1.1. You can obtain the new version at
http://larfis.polymtl.ca/index.php/en/links/openfilters
What is OpenFilters?
====================
OpenFilters is an open source software written in Python for the design of
optical interference filters.
OpenFilters offers multiple tools for the design and optimization of
optical interference coatings, including refinement, the needle method,
the step method, the Fourier transform method and multiband rugates. It
can calculate the transmission, the reflection, the absorption,
ellipsometric variables, phase, group delay, group delay dispersion, the
circle and admittance diagrams, the electric field distribution and the
color of the filter. It can also be used to generate photometric or
ellipsometric monitoring curves.
What is new?
============
The changes in this version include many more target kinds, a tool to
simulate the effect of random fabrication errors, the possibility to
import a material or an index profile from a text file, Sellmeier
dispersion model, as well as many bug fixes. A complete list of changes
can be found at

One big change is in the way material files are managed. Now, user defined
materials are saved in a directory selected by the user. This way, many
users of the same computer can have different sets of materials. It also
avoids the bad practice of writing material files in the "Program files"
directory, which created permission issues with the previous versions of
OpenFilters. To enable this new feature, the first time you use
OpenFilters 1.1, you will be asked to select the directory where to save
your materials.
I am also very excited to announce the release of a Mac version of
OpenFilters. As I do not own a Mac, this version has not been as largely
tested as the Windows version, and I would greatly appreciate all your
feedback.
Sincerely,
Stéphane
