一种能够在高温超高真空条件下传输红外辐射的窗口密封装置。该装置包括夹紧在夹紧法兰的环形边缘和密封法兰的环形边缘之间的窗口。所述密封法兰的边缘包括在其中加工的环形密封旋钮，其上表面具有环形压痕。环形铅垫圈位于密封旋钮和窗户一侧之间。具有粗糙表面的环形铅垫片靠近窗户的另一侧定位，并且TEFLON垫片靠近夹紧法兰的环形边缘定位。提供恒力装置，用于将夹紧法兰推向窗口和密封法兰，从而在两者之间产生密封。所述窗口优选由碱卤化物材料形成。
A window seal apparatus capable of transmitting infrared radiation for use under high temperature ultra-high vacuum conditions. The apparatus includes a window clamped between an annular rim of a clamp flange and an annular rim of a sealing flange. The rim of the sealing flange includes an annular sealing knob machined therein having an annular indentation in its upper surface. An annular lead gasket is located between the sealing knob and one side of the window. An annular lead gasket having roughened surfaces is positioned adjacent to the other side of the window and a TEFLON gasket is positioned adjacent to the annular rim of the clamp flange. A constant force means is provided for pushing the clamp flange toward the window and the sealing flange thereby producing a seal therebetween. The window is preferably formed from alkali halide material.
