Abstract
An isotropic illuminator is described, including a relay lens configured to focus a source image propagated from a source and a lightpipe having an entrance aperture and an exit aperture. The source image is aligned by a folding element to fill the entrance aperture and the lightpipe propagating the source image provides substantially uniform illumination from the exit aperture to a field stop. Focusing a source image propagated from a source, aligning the source image to fill an entrance aperture, and propagating the source image to provide substantially uniform illumination from an exit aperture to a field stop is also described. A specimen review system including a specimen stage configured to receive specimens for viewing, a source of illumination providing illumination to the specimen stage, and a review scope configured to review specimens on the specimen stage is also described.
