Abstract
Device for protecting a surface against dirt and corrosion by gas sweeping and mainly protection device for the front surface of an optical system or a transparent window, characterized in that the surface to be protected is isolated from the ambient atmosphere by means of of a room inside which a protective gas circulates; this enclosure is closed at one end by said surface and at the other end by a perforated wall, drilled with one or more holes intended for the passage of a radiation, this or these orifices being partially sealed with the aid of perforated surfaces such as a grid of metal wires, plastics, textiles; the geometrical characteristics of said perforated wall, such as dimensions and shapes of the holes, transparency, ratio of hollow parts to full parts as well as their characteristics of surface electrical conductivity are chosen in such a way that, offering the minimum obstacle to radiation, ensures with a minimum protective gas flow, an overpressure in the room sufficient to prevent any entry of the elements of the ambient atmosphere and an exit velocity of said gas sufficient to prevent any deposition of impurities on the perforated wall and to overcome the electrostatic field due to to its eventual electrification.
