Abstract
A system and method for maintaining the face of an optical window at a desired axial position with respect to the face of a high pressure housing, suitable for use in a high pressure optical flow cell for a real time optical particle monitoring system. The window fits within a mounting hole that extends through the pressure housing. The window has a smaller-diameter cylindrical end portion extending to the high pressure side and an opposite larger-diameter cylindrical end portion, with a shoulder between the cylindrical end portions. A threaded retaining member axially compresses a gasket, o-ring, or other compliant sealing member between the shoulder of the optical window and a corresponding shoulder in the mounting hole, creating a static seal and maintaining the high pressure face of the optical window at a desired position over a wide range of temperatures and pressures.
