  • Patent number: 4948937
    Abstract: An apparatus for heat cleaning a semiconductor material by producing a uniform thermal distribution in the area of the material being cleaned. In one arrangement a heater block is positioned between a lamp nad a photocathode. The semiconductor material layer of the photocathode is directed away from the lamp. The heater block absorbs the entire range of wavelengths radiated by the lamp but reradiates only long wavelengths to the photocathode. In another arrangement, a laser has its beam directed to a focusing and scanning system. The resultant beam is directed to a photocathode which is positioned with its semiconductive layer directed toward the beam.
    Type: Grant

  • Patent number: 4661079
    Abstract: An image intensifier tube and a method of making same are disclosed wherein veiling glare caused by the amplification of off-axis light is reduced. A face plate is formed from a fused assembly of a glass rod having a low reflective, light absorbing layer thereon, a cladding tube and a jacket tube. The fused assembly is then cut into wafer-shaped slices and the ends polished.
