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.
