Optical Thin Film Software from USA
Popular for more than 30 years

Filmstar is one of the best optical film software in the world.

Much closer to the actual production process, more thoughtful consideration of the user's operating habits.

Software serves engineers, software serves process.

Filmstar Introduction

Filmstar is one of main products from FTGSoftware.

Filmstar is established since 1986 and good at thin film design, inversion fitting, material refractive index(n&k) fitting, measurement control, data management&analysis, coating training and so on.

The development team of Filmstar has many years of working and business handling experience in thin film coating industry. They are well aware of the importance of computer-aided technology and process automation.

Filmstar is more in line with the process and product features by combining software development technology and actual actual process characteristics of coating industry.

Filmstar has optimization (many optimization strategies including Needle and Buffer), refractive index fitting (Dielectric, semiconductor and metal materials, both substrates and thin film layer), inversion simulation (thickness, Tooling factors, coating rate, angle), color calculation(customized light source), data import and export and other basic functions.

Filmstar has development platform such as BASIC and WORKBOOK. There are many examples in BASIC development platform, What the user need to do for a secondary development is only to set the parameters and path of their process data. WORKBOOK is actually an Excel file and then it can take full advantage of Excel's width (many cells) and depth (functions,formulas,feature settings, etc.) as well as Filmstar's own fast optimization & calculations to extend the optimization targets and summarize the results.

In terms of data processing and user interface, Filmstar supports interworking and embedding with Excel. It can generate files of .xls and .doc without opening Excel and Word. It can export of quality pictures and PDF files by FSPlot and can set the template report by ReportGenerator and so on.

A database module is also available for the management and analysis of thin film design, process data and so on.

Filmstar makes your work even more powerful and creates value for you!

Frequently Asked Questions

If on Win7, please refer to compatibility on Win7
  1. Please do not plug the USB key into the computer, so that the system (Windows) can identify the hardware and find the right driver. If it fails, please check the hardware changes in the control panel and device manager to install the driver.
  2. If you have installed a free version before, please completely uninstall it before installing the new software.
  3. Download the newest setup file from the website and get the password from update email or support email.(If no, please Contact Us).
  4. You need choose 'Security ID Module' during installation, if wrong, please reinstall it.
  5. Please plug USB key to use the software after the installation is finished.
If you are already using Filmstar and are now ready to install Filmstar on a new computer and transfer the old data, please follow these steps:
  1. Install Filmstar on your new computer following the above the steps.
  2. Assuming for 2 computers, Filmstar are installed on C: \ Winfilm, if not please change the paths corresponding.
  3. Copy filders Design,Index,Data of C:\winfilm\ from the old computer to that of new computer.
  4. Copy file Design1.ini of C:\Winfilm\Config\ from the old computer to realted folder on new computer. Please jump this step if you have not configured it.
  5. Please not attach the usb key before you finish the installation.
  1. To disable UAC, from Control Panel select User Accounts and locate the Turn User Account Control... link. Clear the UAC checkbox and reboot. Disabling UAC gets rid of annoying 'Windows needs your permission to continue' dialogs. On the other hand, you (or your IT department) might not want to disable the feature.

    More about disabling UAC: Vista,Windows 7

  2. After installation, if there is still problem, right click and select 'Run as administrator'. Then select Allow. The next time the program runs normally
  3. In reponse to This program might not have installed correctly we found no problem after clicking This program installed correctly.
  4. If the issue is still there, please Contact Us.
After opening a design or updating the refractive index information, a hint as shown in the following figure was found, indicating that there is a layer symbol that is not assigned a refractive index in the thin film stack.

You can check it through click Design -> Group editor, then click Show Indecies at the right-bottom corner. A dialog is shown as below:

After comparison, we know that the symbol 'L' is not set to a material as expected.

Then we need come back to Setup -> Film Indices and add material to 'L':

Of course, you can also replace 'L' with 'M' which has a pre-set material if you know the material of 'M' is really you want to use.
