Dye-based filter

摘要

A display includes a light source. The display also includes a filter positioned to receive light from the light source. The filter is a dye-based filter and attenuates light in the infrared range. The filter can be configured to have a very sharp spectral cutoff. The filter can be an NVIS filter. The display can be utilized in an avionic display system with night vision equipment. The filter can include a host polymer doped with a dye including cobalt or nickel.
