Thin Film Coating Examples

TFCalc is capable of designing multilayer coatings for many applications. To aid the designer, 36 sample designs are included with TFCalc.

Color Correction

TFCalc can design coatings that control the color of transmitted or reflected light. For example, the graphic below shows how a 2800K source was corrected to transmit light having an (x,y) color of (0.38,0.38). The coating consists of 6 layers of SiO2 and TiO2.

Color filters of virtually any color can be designed.

Plot of color filter design

Using TFCalc 3.4 or later, it is even possible to control the color of light reflected by both sides of a coating. For example, the color of reflected light could be blue on one side and red on the other side.
