ALZENAU, GERMANY—ICE (Intl. Converting Exhibition) honored Applied Films with its 2005 Innovation Award for Applied Films' technology for producing color shift layers on plastic film by using electron-beam evaporation, the Fabry Perot Filter. When viewed from different angles, the colored shift layers change their reflected color.
The Fabry Perot Filter consists of a three-layer stack: a thick metallic base layer on the plastic film acts as a mirror (aluminum), a middle transparent oxide layer (AI2O3) allows light to reflect in different colors depending on its thickness, and a top semi-transparent thin metallic layer (aluminum). Applied Films' TOPBEAM system can produce Fabry Perot Filter layers with a typical coating speed of 20 meters per min.
