<p>Systems and methods of achieving optimal light transmittance through a gas (16) and light transmittance region. This invention is directed at the application of specific activated carbon based materials for the protection of imaging lenses (12) which are targeting optimal transmittance at specific wavelengths. Specifically, it outlines a use of a use of a specific type of carbon to obtain improved/constant transmittance at a specific waverlength or range of wavelengths. In addition, it also presents the use of a mixture of activated carbon types in order to obtain improved/constant transmissions over a broad range of wavelengths.</p> |
