Abstract:
A Raman fiber optic probe assembly for use in a hostile environment comprising:a probe housing having a pressure vessel side adapted to be in contact with said hostile environment and a laboratory side adapted to be in contact with a non-hostile environment;an incident fiber optic penetrator adapted to penetrate and seal to said housing having a pressure vessel portion and a laboratory portion and having an incident window positioned to allow optical access to said pressure vessel side of said housing, said incident fiber optic penetrator adapted to mount an incident fiber optic cable in said laboratory portion, said incident fiber optic cable being optically connected to said incident window;a collecting fiber optic penetrator adapted to penetrate and seal to said housing having a pressure vessel portion and a laboratory portion and having a collecting window positioned to allow optical access to said pressure vessel side of said housing, said collecting fiber optic penetrator adapted to mount a collecting fiber optic cable in said laboratory portion, said collecting fiber optic cable being optically connected to said collecting window;said incident fiber optic penetrator and said collecting fiber optic penetrator positioned in said housing such that the axis of the incident fiber optic cable and the axis of the collecting fiber optic cable form an angle of substantially 90.degree..
