Title:
ENDOSCOPE LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/221014
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress variation in color balance of light beams emitted from distal ends of scopes even when scopes having different light guide diameters are combined. Provided is an endoscope light source device (10), comprising: a plurality of solid-state light sources (1, 2); a plurality of collimator lenses (11) for converting light beams emitted from the solid-state light sources (1, 2) into substantially parallel light beams; a multiplexing optical member (4) for multiplexing the substantially parallel light beams obtained by conversion by the collimator lenses (11); a light amount adjustment mechanism (5) disposed between at least one of the solid-state light sources (1, 2) and at least one of the collimator lens (11) and capable of adjusting a peripheral light amount from each of the solid-state light sources (1, 2); and a condensing lens (7) for condensing the light beams from the solid-state light sources (1, 2) multiplexed by the multiplexing optical member (4) to cause the light beams to enter the end surface of a light guide (8) of an endoscope.
