Why TFCalc?

Why is TFCalc used by so many? A brief answer:

TFCalc is easy to use
TFCalc is a stable, reliable tool that works on Windows
TFCalc has the features that coating designers need
TFCalc has features that other design programs do not have
TFCalc allows the user to define an unlimited number materials, substrates, and illuminants
TFCalc allows layers to have variable index, or to be a mixture of materials
TFCalc has powerful optimization capabilities, such as
- needle optimization
- global search
- sensitivity optimization
- optimizing cone-angle targets
TFCalc provides a cost-effective solution

More information about TFCalc

Can maintain the symmetry of a design while it’s being optimized.
Helps the designer locate the designs that minimize the merit function.
Utilizes needle optimization, a powerful tool in designing multilayer coatings.
Allows for needle/tunneling, so the designer has more designs from which to choose when it comes to manufacturing.
Computes EFI (electrical field intensity) to calculate performance of thin film coatings.
Utilizes Monte Carlo method to generate random designs…and then displays results!
Can compute the sensitivity of each coating layer of a design.
Can simulate the output of an optical monitor, used in the manufacturing thin film coatings.
Determines the refractive index of a thin layer coating using variable materials and fitting a dispersion formula.
All computations are done with 10-byte extended-precision numbers, which offer about four additional digits. This is important for designs having many layers.
