Abstract:
An optical device includes an aperture stop that limits an angular extent of light from an illuminated sample. A first lens is positioned between the aperture stop and a detector plane. A second lens is positioned between the first lens and the detector plane and is operable to map light from the aperture stop to the detector plane such that the light is averaged at the detector plane.
