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.
