Abstract

This endoscope light source device (100) comprises: a laser light source unit (110) that emits a laser beam; an LED light source unit (130) that emits an LED beam; and an optical path merging member (160) that merges the optical path of the laser beam and the optical path of the LED beam. The etendue of the laser light source unit (110) is smaller than the etendue of the LED light source unit (130). The optical path merging member (160) has a reflection surface (162) that reflects the LED beam, and has, in a region of the reflection surface (162), an opening (164) that lets the laser beam pass through. The optical path merging member (160) reflects the LED beam such that the central axis of the optical path of the LED beam reflected by the reflection surface (162) matches the central axis of the optical path of the laser beam that has passed through the opening (164).

Description

technical field [0001] The present invention relates to an endoscope light source device connected to an endoscope scope. Background technique [0002] In recent years, in endoscopic inspection, in addition to normal light observation using white light, special light observation using narrow-band wavelength light to improve the visibility of a living body has been performed. As a light source for generating special light, the use of laser light has drawn particular attention from the viewpoint of narrow-band characteristics, and various combinations of special light have been developed. Japanese Patent Application Laid-Open No. 2013-013560 discloses, as an example, the following structure: In order to enable the observation of the oxygen saturation of the superficial blood vessels, the optical path of the laser light is aligned with the white light through a reflection plate arranged in the optical path of the white light to reflect the laser light. The optical paths of lig...
