摘要： A image intensifier tube (14) includes a housing (18) carrying a photocathode (22) and a microchannel plate (24). The housing also receives axially extending fine-dimension spacing structure (22a) interposed around an active area 22b of the photocathode and the microchannel plate to establish and maintain a selected fine-dimension, precise PC-to-MCP spacing between these structures. The housing includes yieldable deformable electrical contact structure (56′) for establishing and maintaining contact with the microchannel plate, and yieldable deformable sealing structure (58) allowing axial movement of the photocathode relative to the housing structure as the tube is assembled and the axial spacing structure controls PC-to-MCP spacing. The result is that the PC-to-MCP spacing dimension of the tube is largely isolated from dimensional variabilities of the housing and is established and maintained precisely during manufacturing of the tube despite stack up of tolerances for the housing and its components.

摘要： A photocathode emitter as a source of electron beams, having an optically transmissive substrate patterned to define a protrusion, heat conducting material occupying the space surrounding the protrusion, and a photoemitter layer over the protrusion. The photoemitter is positioned on the side of the substrate opposite the surface on which the illumination is incident, and has an irradiation region at the contact with the top of the protrusion patterned on the substrate, and an emission region opposite the irradiation region, these regions being defined by the path of the illumination. The heat conducting material around the protrusion conducts heat away from this focused region of illumination on the photocathode to allow higher currents to be achieved from the photocathode and thus permits higher throughput rates in applications including electron beam lithography. In one version, the photocathode is fabricated using microfabrication techniques, to achieve a small emission spot size.

摘要： A night vision device (10) with an image intensifier tube (14) includes an improved microchannel plate (22) which has an extraordinarily low indigenous population of gas molecules. Because of this low population of gas molecules, positive ions produced from these gas molecules in the high voltage operating environment of the image intensifier tube (14) are of such a low number that the image intensifier tube (14) will operate for a satisfactory service life even though the microchannel plate (22) has no ion barrier film. The microchannel plate (22) is also spaced much closer to a photocathode (20) of the image intensifier tube (14) than has heretofore been possible. Thus, improved gain and reduction or elimination of image halo also results from the present invention.

摘要： An intensified hybrid solid-state sensor includes an imaging device comprising a solid-state sensor assembled with an image intensifier cathode, microchannel plate (MCP), and body envelope. This device combines the best functions of the image intensifier, good signal-to-noise ratio and high logarithmic gain, with the electronic read-out functions either of a Complementary Metal Oxide Semiconductor (CMOS) or charged coupled device (CCD).
