The optical thin film design software ThinFilmView (abbreviated TFV) has a wealth of features and overwhelming ease of use. It can be used not only in the research and development department but also in the production department, such as product startup with vacuum deposition equipment and sputtering equipment, and quality control.

TFV features

New optimization

Freehand mode!
Bidirectional operation of film thickness change on design screen and characteristic change by mouse on graph screen is possible.
Operation of freehand mode

Real time calculation

Calculations are performed immediately when the film thickness or material is changed, and the results are displayed in graphs and tables.
There is no need to press the calculation execution button.
The film thickness can be easily changed with a mouse or keyboard (arrow keys, PgUp, PgDn keys).

Sheet format editing screen

The screen for editing design data is in the form of multiple sheets.
There are 20 sheets.
The calculation results of each sheet are superimposed on the spectrum graph and incident angle graph.

Spectrum and film thickness types and units

Spectrum types Units
Wavelength Å, nm, μm, mm
Frequency PHz, THz, GHz
Wave number cm-1, μm-1, 2π/cm
Angular frequency rad/fs
Energy eV, keV
g-number λ/λ0
Film thickness types Units

Multi window

Graphs and numerical values such as spectral characteristics, incident angle characteristics, color calculation, and optical deposition monitor can be displayed simultaneously.


You can switch between English, Japanese and Traditional Chinese.

High resolution display compatible 4K ready!

It supports Windows scaling. It is an easy-to-see display even on high resolution displays.
You can also specify the font size.
