Abstract
An optical element is provided that may be used for collecting optical radiation incident at large angles of incidence. The element may include a grating window formed of grating elements that may collect large incident angle radiation and reflect that radiation, e.g., under total internal reflection in a substantially normal direction. A lens or lens array may be used to collect the internally reflected radiation and focus that radiation to a detector. Example detectors incl...
