MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202637067016 A) filed by Photonis France on May 28, 2026, for Image Intensifier Tube And Associated Night-Vision Device.
Inventors include Lavoute, Pascal; Planche, Olivier; and De Jong, Alwin.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention relates to an image intensifier tube comprising the following elements, which are attached inside an internal vacuum chamber: an input window (15) configured to receive and transmit photons; a photocathode (16) capable of converting photons transmitted by the input window (15) into primary electrons, the photocathode (16) being attached to an inner face of the input window (15); an electron multiplier (18); a holder (30) configured to hold the electron multiplier (18) within the internal vacuum chamber; a phosphorescent screen (20); and an optical output interface (21) configured to capture the photons emitted by the phosphorescent screen (20) in order to transmit them at the output of the image intensifier tube. The electron multiplier (18) is clamped in the holder (30) by means of two damping rings, a first damping ring being arranged on a first face of the electron multiplier (18), and a second damping ring being arranged on a second face of the electron multiplier (18), the damping rings being made of a material having the following features, which are defined for temperatures of the order of 25°C: a Young's modulus of less than or equal to 200 GPa; a density greater than or equal to 7200 kg/m3; a resistivity at 300K of less than 1 O.m.
