Abstract
A light source device includes an excitation-light light source which emits excitation light, a reflection member which reflects the excitation light, a lens which is arranged on an optical path of the excitation light which leads from the excitation-light light source to the reflection member and refracts the excitation light, a housing which houses the reflection member in a hermetically sealed internal space, an operation member which is exposed from the housing in a direction which intersects the optical path and is moved towards the inside and outside of the housing, and an adjustment mechanism which adjusts a length of an optical path between the reflection member and the lens in linkage with the operation member which is moved towards the inside and outside of the housing.
