| 发明名称 | Variable transmittance optical filter and uses thereof | ||
| 摘要 | Variable transmittance optical filters capable of transitioning from a light state to a dark state on exposure to UV radiation and from a dark state to a light state with application of an electric voltage are provided. The optical filters comprise a switching material that comprises one or more chromophores that have electrochromic and photochromic properties. | ||

| 主权项 | 1. An optical filter capable of transitioning from a light state to a dark state on exposure to UV radiation and from a dark state to a light state with application of an electric voltage, comprising: a) a first and second substantially transparent substrate; b) a first and second electrode disposed on the surface of at least one of the substrates; c) a switching material disposed between the first and second substrates and in contact with the first and second electrodes, the switching material comprising one or more chromophores having both electrochromic and photochromic properties. | ||
