Claim Text:
1. A disposable polymer sheath for receiving an optical probe in a bioprocessing vessel, said disposable polymer sheath comprising: a hollow tubular member for installation into a bioprocessing vessel, said hollow tubular member comprising an open end exterior to the bioprocessing vessel for receiving an optical probe, a closed end interior to the bioprocessing vessel, a sidewall, and an alignment feature configured to orient an optical probe within said hollow tubular member, and wherein the hollow tubular member is impermeable to fluid within the bioprocessing vessel; an optical sampling region comprising at least two opposing surfaces, at least a portion of said surfaces comprising a polymer being at least partially optically transparent to near-infrared electromagnetic radiation; wherein at least a portion of said optical sampling region is at least partially compressible whereby an optical path length is formed by compression.
