Apparatus for removing X-rays and other harmful radiation from visible radiation

摘要

The present invention provides an apparatus which removes harmful radiation from the visible image producing radiation emitted by a cathode ray tube. The apparatus comprises an image conveying member for conveying by reflectance the visible image originating from a cathode ray tube and an image receiving member for receiving the image conveyed by the image conveying member. The image conveying member is comprised of a reflective layer and an absorptive layer. The reflective layer of the image conveying member is substantially reflective of visible electromagnetic radiation and substantially transmissive of electromagnetic radiation of wavelengths shorter than visible radiation. The absorptive layer of the image conveying member is comprised of a material capable of absorbing the electromagnetic radiation transmitted by the reflective layer of the image conveying member. The image receiving member is comprised of a material which is substantially transmissive of electromagnetic radiation of wavelengths shorter than visible radiation.
