Abstract

Quite often, the strongest motivation for the selection of an IR window is its transparency in the particular region of the spectrum in which a sensor behind it views the outside world. Generally, the requirement for high transmission in the sensor passband overshadows considerations about absorption in other parts of the spectrum. The existence of high-power radiation sources at wavelengths outside the window passband makes the window highly susceptible to damage. The application of IR-resonant meshes is being investigated as a means of reducing this susceptibility without intolerably degrading passband transmission.
