<p><P>PROBLEM TO BE SOLVED: To provide an optical fiber probe subjected to measurement without replacing the the probe as a whole, when changing the kind of measurement regarding a measuring object. <P>SOLUTION: This optical fiber probe 1 comprises the probe body 2, a measuring part 3, and an outer cylindrical cap 4 attached detachably to the main body for storing the measuring part to be coupled to the body. A protrusion 32 on a base end face of the measuring part 3 is engaged with a recess 22 of the body 2, a spacer 23 on an end face of the body is brought into contact with the base end face of the measuring part 3, each core 31 of the measuring part is brought into contact with an end face of each core 21, on the base end face, and the each core is connected under the condition where the each core is conformed with an optical axis. The cap 4 is attached to the main body to be screwed in astride a range from the measuring part 3 to a small-diameter part in the main body 2. An edge part 41a of an opening 41 on a front end face of the cap 4 with a projected measuring area 33 of the measuring part 3 contacts with a front end of a stepped part 3b of the measuring part 3 at slight pressure so as to press the measuring part, and the measuring part 3 is coupled with the body 2 under the condition that each core 31 and each core 21 hold the connection with coinciding of the optical axes. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
