  • Patent number: 11466228
    Abstract: An improved method of sealing a window into an aperture in a body uses a lubricant comprising polymer particles suspended in a volatile, low viscosity, low surface tension carrier fluid. The carrier fluid is applied to one or both of the sidewalls of the window and aperture, and the window is pressed into the aperture such that the carrier fluid evaporates, leaving the polymer particles to fill interstitial surface voids, while enabling the sidewall of the window to make intimate mechanical contact with the sidewall of the aperture. While having broader application, the present disclosure finds particular utility in optical characterization techniques based upon the Raman effect and fluorescence probes used in process monitoring and control.
