Abstract
An endoscope light-source device includes a semiconductor laser light source, a first lens group that diverges a low-NA light component of light from the semiconductor laser light source and converges or collimates a high-NA light component of the light from the semiconductor laser light source, and a second lens group that focuses the light passing through the first lens group onto an end surface of a light guide. The first lens group includes at least one aspherical lens.
