TFCalc is capable of designing multilayer coatings for many applications. To aid the designer, 36 sample designs are included with TFCalc.
Anti-Reflection FiltersAlso called AR coatings. Probably the most common type of coating, an anti-reflection coating reduces the reflection (increases the transmission) of the surface on which it is applied. AR coatings may be designed for any part of the spectrum. It is possible to create high efficiency AR coatings (which reduce the reflectance very close to zero for a narrow band of wavelengths), broadband AR coatings, multiband AR coatings, etc. The graphic below shows the performance of a 4-layer design that reduces the reflectance of glass from its usual value of about 4% down to less than 0.1%.
Here is another example of an AR coating: |
