Latest Patents

Tranchant holds a patent for an input screen of a radiographic image intensifying tube. This invention involves a curved input screen that includes a substrate for receiving input radiation and a photocathode supported on the substrate. The output screen converts the electrons emitted by the photocathode into a visible image. To address changes in luminosity due to the curvature of the input screen, an intermediary layer of radially variable thickness is deposited between the substrate and the photocathode. This layer, made from materials like indium oxide, modifies the electron emitting characteristics of the photocathode based on its thickness. Consequently, a thicker intermediary layer near the center compensates for reduced luminosity at the edges of the screen.
