TFStudio is a desktop application for design, analysis and optimization of multilayer optical coatings: anti-reflection stacks, bandpass filters, mirrors.
It's free and open source (MIT license). Get the code, build it yourself, or help out. Contributions are welcome.
Runs entirely in your browser. Explore example designs and live spectra, no install.
Main window: Design Editor + Optical Evaluation, docked
One app for the whole job, from first idea to the deposition chamber.
Lay out a coating layer by layer, pick from a large material library, and set what you want it to do.
Let it tune the layers, or grow a whole design from scratch, to hit your goals.
Check performance and tolerance.
Simulate the real deposition and export files for your chamber's monitoring software.
Drag a 50 % line across the plot and press Run. Eight quarter-wave layers become a flat beamsplitter from 450 to 650 nm.
Set a 450-700 nm AR target in the wizard and run Gradual Evolution. It stops at eight layers with reflectance near zero across the band.
Enter (H L)^8 H in Stack Formula, then map reflectance over wavelength and angle of incidence as a 3D surface.
A few plain facts about the current build.
| Runs on | Windows and Linux. A desktop app, so everything stays on your machine. |
| Works offline | No internet needed. |
| Languages | English, Russian, Chinese and Italian. |
| Chamber export | Layer by layer curves can be exported in .res format that is accepted by spectrophotometer software. |
| License | Free and open source (MIT). |
TFStudio is free and open source, released under the MIT license. The full source is on GitHub. Read it, build it, or send a pull request.
TFStudio is a young project, so bug reports and contributions are especially welcome, whether that's code, an issue, or an idea for what to build next. See the contribution guide to get started, or open an issue.
