ABSTRACT:
An optical filter for providing an enhanced image. The filter may comprise at least one substrate, layers of a low refractive index material and layers of a high refractive index material. The layers are stacked so that the filter blocks passbands at 490 nm and 590 nm as well as other image-confusing radiation. Light which is transmitted by the filter provides an enhanced image for viewing by the human eye as well as nonhuman detectors.
