Claim:
1. A probe for sampling a fluid stream comprising: a tubular housing having a sampling end and an opposite detecting end, said housing having a body that defines at least one flow cell at the sampling end; a mirror disposed in said housing at the sampling end; said mirror having a reflective surface facing the detecting end; a lens disposed in said housing a window disposed in said housing between said lens and the detecting end; a collet disposed in said housing between said window and the detecting end, said collet having an outer wall that defines a counter bore open to the detecting end, a plurality of raceways and a keyway; a first insert disposed in said collet bore, said first insert having a plurality of matching raceways and a key for engaging with the keyway; a second insert disposed in said collet bore between said first insert and the detecting end, said second insert having a plurality of matching raceways and a key for engaging with the keyway; a pitch hollow wave guide disposed within one of the plurality of raceways in said inserts and said collet, said pitch hollow wave guide exiting said housing at the detecting end; a catch hollow wave guide disposed within one of the plurality of raceways in said inserts and said collet, said catch hollow wave guide exiting said housing at the detecting end; a pitch optical fiber disposed within one of the plurality of raceways in said inserts and said collet, said pitch optical fiber exiting said housing at the detecting end; a catch optical fiber disposed within one of the plurality of raceways in said inserts and said collet, said catch optical fiber exiting said housing at the detecting end; an inner tube disposed in said housing adjacent to said second insert at the detecting end, said end tube surrounding said hollow wave guides and said optical fibers, said inner tube having male threads for cooperating with female threads inside said housing such that said inner tube can retract into or extend out of said housing with a turning motion; and wherein, when said inner tube is turned in one direction in relation to said housing, said inner tube retracts into said housing, causing said first insert to grip said hollow wave guides and said optical fibers such that they are fixed in place in relation to said lens.
