Method and apparatus for sealing an optical window in a spectroscopic measuring device |
| abstract |
The invention comprises a spectroscopic measuring device, a seal for such a device, and a method for sealing such a device. A window having a first and second portion is disposed in a cavity of a housing. The first portion is adjacent to an exterior of the device and has a first diameter less than a second diameter of the second portion, thus forming a shoulder therebetween and defining a gap between the first portion and an interior housing surface. An intermediate ring with a, metallic coating is disposed in the gap adjacent to the shoulder. A retaining ring is disposed in the gap adjacent to the intermediate ring. An exposed surface of the retaining ring is flush with an end housing surface and an exposed sapphire surface. A portion of the exposed retaining ring surface is electron beam welded to a portion of the end housing surface. The housing, intermediate ring, and retaining ring comprise a nickel-molybdenum-chromium alloy. A method for sealing a spectroscopic device is disclosed as comprising the steps of: disposing a window with a shoulder in a cavity of a housing; disposing an intermediate coated O-ring or C-ring adjacent to the shoulder and between the window and the housing; disposing a retaining ring adjacent to an exterior of the device and between the window and the housing; electron-beam welding a portion of an exposed retaining ring surface to a portion of an end housing surface. |
