Abstract: A light radiating unit provided at a distal end portion of an optical fiber includes a first light radiating unit having a predetermined length in a longitudinal direction and capable of radiating therapeutic light having first intensity and a second light radiating unit connected consecutively to the first light radiating unit in the longitudinal direction and configured to radiate therapeutic light having second intensity lower than the first intensity. Consequently, even when a bladder, which is a hollow organ, and a urethra, which is a conduit, are irradiated with the therapeutic light at a time, intensity of the therapeutic light with which surfaces (inner wall surfaces) of respective parts are irradiated is equalized.

Abstract: An optical unit for a wavelength-selecting switch according to the present invention comprises: an input port; a dispersion section that produces wavelength dispersion of input light that is input from the input port; a light-collecting element that collects the light dispersed by the dispersion section; an output port; an optical path correction section that shifts the light that is dispersed by the dispersion section; an adjustment section that changes the amount of shift produced by the optical path correction section; and a casing that hermetically seals the input port, dispersion section, light-collecting element, output port, and optical path correction section. The casing has an optically transparent section in a location onto which the light that is collected by the light-collecting element is directed. The adjustment section is arranged outside the casing. The optical path correction section can be controlled from outside the casing by the adjustment section.
