Patent ID: 8836939

Claim:
A probe detachably connected to an optical measurement apparatus, comprising: a fiber that emits, from a distal end thereof, light supplied from a proximal end thereof by the optical measurement apparatus, and outputs, from the proximal end to the optical measurement apparatus, reflected light and/or scattered light from an object to be measured, the reflected light and/or scattered light entering from the distal end; a covering member that covers a side face of the fiber; a cap that covers a distal end of the probe, a standard object being provided on a surface of the cap facing the distal end of the fiber, the standard object being configured for a calibration measurement by light emitted from the distal end of the fiber; an adhesive member that adheres the cap to the distal end of the probe and is made of an adhesive having an adhesive strength with respect to the covering member, the adhesive strength decreasing by application of heat; a heat-generating portion that generates heat to be applied to the adhesive member; and a thermal conduction portion that conducts, to the covering member, the heat that decreases the adhesive strength of the adhesive material with respect to the covering member, wherein the cap including the standard object becomes removable from the probe after the calibration measurement due to melting of the adhesive, the adhesive strength of the adhesive with respect to the covering member decreases to be lower than an adhesive strength of the adhesive with respect to the cap when the heat generated during the calibration measurement is applied to the adhesive member and the adhesive is melted, the thermal conduction portion conducts, to the adhesive member, the heat generated by the heat-generating portion, and once the cap is removed from the probe, the optical measurement apparatus detects characteristics of the object to be measured.
