1. An endoscope, comprising:
an elongated endoscope body;
an optical fiber extending along the endoscope body, the optical fiber configured to direct therapeutic light and illumination light longitudinally along the optical fiber to a distal portion of the endoscope body, the therapeutic light and the illumination light having different wavelengths; and
a wavelength-sensitive light separator disposed at a distal portion of the optical fiber, the wavelength-sensitive light separator configured to direct the illumination light to exit the optical fiber laterally through a lateral side of the optical fiber at the distal portion of the optical fiber and permit the therapeutic light to exit the optical fiber longitudinally through a distal end of the optical fiber.
