Abstract
An endoscope apparatus includes an insertion unit having at a distal end thereof a light-incident end portion that captures observation light from a subject, the insertion unit being insertable into an object to be examined; and an ultraviolet light source unit that emits ultraviolet light. The light-incident end portion is provided with an ultraviolet light absorption filter that generates heat by absorbing the ultraviolet light emitted from the ultraviolet light source unit.
Claims8
An endoscope apparatus, comprising:
- an insertion unit having at a distal end thereof a light-incident end portion that captures observation light from a subject, the insertion unit being insertable into an object to be examined;
- and
- an ultraviolet light source unit that emits ultraviolet light,
- wherein the light-incident end portion is provided with an ultraviolet light absorption filter that generates heat by absorbing the ultraviolet light emitted from the ultraviolet light source unit.
A medical imaging device detachably connected to an endoscope including an insertion unit having at a distal end thereof a light-incident end portion that captures observation light from a subject, the insertion unit being insertable into an object to be examined, the light-incident end portion having an ultraviolet light absorption filter that generates heat by absorbing ultraviolet light, the medical imaging device comprising:
- an imaging unit that receives the observation light and generates an imaging signal;
- and
- at least one dichroic mirror provided in an optical path of the observation light, the at least one dichroic mirror being configured to guide, to the imaging unit,
- the ultraviolet light from the ultraviolet light source unit to the ultraviolet light absorption filter by one of transmission and reflection, and
- at least light having a wavelength in a visible region of the observation light to the imaging unit by the other one of transmission and reflection.
