More Information
Summary:An optical probe that is easy to manufacture and that can capture a tomographic image with high resolution has a proximal end to be connected to an OCT device and a distal end from which observation light exits, and includes an optical fiber, a Grin lens corresponding to a light collection optical system and a light deflection optical system that are optically connected to the optical fiber at the distal end, a sheath that extends in a first direction, that includes a curved surface portion having a curvature in a section perpendicular to the first direction, that accommodates the optical fiber and the Grin lens in the first direction, and that causes the observation light deflected to exit through the curved surface portion laterally, and a compensation portion that is accommodated in the sheath, that extends in the first direction over a range including a part of the optical fiber and the Grin lens, and that compensates an optical aberration that occurs when the observation light passes through the curved surface portion.
