ABSTRACT:
A fiber optic probe adapted to be immersed in a fluid medium has an opening at one end in which is accommodated an optical window through which light may be transmitted from and to the optical fibers. Seals between the optical element and the probe body are provided to prevent the leakage of fluid past the window into the probe body. One or more resilient biasing springs constantly apply a yieldable, compressive force on the seals regardless of thermal expansion and contraction of any part of the probe.
