Electrochromic layers for active optical filters

Abstract

In principle, electrochromic materials permit continuous variation of the absorption and reflection characteristics of functional optical components. This has led to a broad range of innovative developments. The important and essential properties of electrochromic applications are presented for the materials used most frequently and various system designs are explained with reference to some examples. Three applications for electrochromic systems are introduced - the electrochromic display, the continuously dimmed automobile mirror and the so-called "smart window".
