Abstract
A light therapy diagnostic device comprising a shaft, an optical waveguide disposed in a lumen of the shaft and being movable forward and backward in a longitudinal direction of the shaft, and a transparent member disposed in the lumen and located distal to the optical waveguide, wherein: the optical waveguide guides a first light and a second light; the shaft has a lateral emission window which allows the first light and the second light to be emitted toward a lateral direction and a distal emission window which allows the first light to be emitted toward a distal direction; the optical waveguide includes a core and a clad, wherein a distal end surface of the core is inclined with respect to an optical axis of the optical waveguide; the first light passes through the transparent member in a state where the optical waveguide is in contact with the transparent member.
