发明名称 PDT Magnifier Camera Illumination
摘要 A device that enlarges text and images to enable a low vision person to see the text and images includes a hollow structure including a top housing and a bottom housing that are connected to one another. A camera aperture is formed in the bottom housing and a transparent light guide lens is disposed in closing relation to the camera aperture so that all light entering the camera aperture must first pass through the light guide lens. A cavity formed in the light guide lens is bounded by walls that are positioned at a critical angle. Light-emitting diodes are positioned at critical locations about the periphery of the light guide lens to illuminate the object being viewed.
