Abstract
A flow cell for fiber optics spectroscopy having a radiation transparent window for the transmission of radiation uses a dual O-ring arrangement to prevent leakage of a medium undergoing evaluation around the window and a vent for indicating leakage between the O-rings. The arrangement also provides for the use of an O-ring to urge the window against a retainer that holds a lens to direct radiation into the window. Biasing of the window against the lens retainer and the use of a radial O-ring arrangement allows precise control of the separation between windows in the total path length for radiation travel across a fluid sample.
