Abstract: An endoscope includes an insertion portion, a distal end rigid member, and a channel tube. The distal end rigid member is provided on a distal end side with respect to the bending portion of the insertion portion, and includes an illumination window, an observation window, and a treatment instrument opening. As the distal end rigid member moves relative to the bending portion in a distal end direction of a longitudinal axial direction, the distal end rigid member can change from a first state in which a distance between a proximal end surface of the distal end rigid member and a distal end surface of the bending portion is fixed to a first distance to a second state in which the distance is equal to a second distance longer than the first distance.

Abstract: A measurement probe is configured to be detachably attached to an optical measurement apparatus. The measurement probe has at an end surface thereof exit ends of a plurality of optical fibers. The optical measurement apparatus includes: an imaging unit that receives rays of light transmitted from the exit ends of the plurality of optical fibers and performs photoelectric conversion in order to generate and output an electric signal; and a partition unit that optically isolates paths for the rays of light transmitted from the exit ends of the plurality of optical fibers, from one another in a space from the end surface to a light reception surface of the imaging unit. The partition unit comes into contact with the end surface at one end of the partition unit, and comes into contact with the light reception surface of the imaging unit at another end of the partition unit.
