Claim 12:
13. A method of operating an optical channel comprising: directing light through an entrance pupil of an optical channel body wherein the optical channel body is configured such that a first distance at the entrance pupil between a front surface and a back surface of the optical channel body is different from a second distance at the exit pupil between the front surface and the back surface, wherein a wedge overlay is located adjacent to the front surface of the optical channel body opposite the entrance pupil, and wherein at least some of the light entering the optical channel body via the entrance pupil is reflected from a front overlay surface of the wedge overlay back into the optical channel body towards the back surface of the optical channel body, wherein disposition of a distal end of the wedge overlay relative to the entrance pupil filters incident light passing through the entrance pupil such that only wavelengths above or below a threshold are reflected from the front overlay surface into the optical channel body while remaining wavelengths reflected from the front overlay surface are not.
