    Abstract: An illumination station for viewing reflection copy images such as documents, photos, and the like having a back-plate against which a reflection copy image is disposed for viewing, one or more overhead light sources disposed in a top member, and a reflector at the base of the back-plate configured to reflect incident light on the lower portion of the back-plate. The use of a reflector provides enhanced illumination to the lower portion of the back-plate and therefore improves the uniformity of illumination of the entire back-plate, and, consequently, of the reflection copy image affixed thereto.
