Provided is an optical probe, the diameter of which decreases at the tip. This optical probe is equipped with a proximal end connected to an OCT device and a distal end for emitting observation light, and is further equipped with: an optical fiber; an optical connector connected to the OCT device; a GRIN lens that functions as a light-collecting optical system and as a deflecting optical system and is optically connected to the optical fiber at the distal end; a needle for rotatably housing the optical fiber and the GRIN lens; a handpiece for holding the needle and rotatably housing one section of the optical fiber between the proximal end and the distal end; and a support tube, the proximal end side of which is affixed to the optical connector and the distal end side of which is rotatably housed in the handpiece. Furthermore, the outer diameter of the needle is smaller than the outer diameter of the support tube. |
