FilmMaker2.1


Overview

FilmMaker2.1 is supplied with every Intellemetrics optical monitoring system. It comes pre-installed on every Intellemetrics Optical Monitor, but more importantly it can also be installed on your design PCs. It allows customers to do the following general tasks;

  • Create a filmstack design from scratch or read one in from a 3rd party design package (e.g. TFCalc, Macleod, Optilayer, Filmstar, etc).
  • Model the filmstack design.
  • Create an optical monitoring scheme from the filmstack design including substrate materials, dispersion, test glass changes, monitoring configuration, etc.
  • Use a range of tools to analyse the performance of the optical monitoring scheme in a real-life coating process before committing to doing an actual coating run.
  • Analyse the data from previous coating runs to help optimise future coating runs.
  • Output a Project file containg all of the information to perform an automated coating run.

Current version: Version 2, Release 1, Build 4.

The main FilmMaker menu bar

Select colours for each layer.

Colours are carried through to all graphs and even into FilmDirector for the live plots during a coating run.

Many of the important parameters can be set in the Ribbon Bar.
Example model output for a FAR-IR filmstack monitored in a non-quarter wave mode.
Example model output for a visible narrow band filter using a 3 cavity design and monitored in a quarter wave mode.

An example FilmEditor screen showing the modelled waveform and the processed waveform for layer 6 of a multilayer stack.

All of the important optical monitoring parameters can be edited live on this screen and their effects on the processed optical signal can rapidly be seen.

In the image on the left, the HoldOff, Latency, turning points, fitted curves etc are all show in colour coded form for easy visualisation.

Various optimisation routines are running in the background to minimise cut errors in response to the parameter values that you select.

An example of the FilmSimulator screen.

This shows a 44 layer narrow band filter design. The theoretical target spectra is show, along with the results from 10 simulation runs.

Error plots show the variation from run to run in cut error for each layer allowing you to see the sensitivity of the design to various layers.

You can even use the Simulator to see what the resultant spectra would look like if the whole run was performed using just a crystal controller.

Graphs can be zoomed in a number of different ways, copied to the clipboard, saved as BMP files, and many can be saved to CSV files for analysis in third party software.
