Abstract
The light source device includes a first light source component, a fluorescent component, a first illuminance homogenizer, and a relay optical system. The first light source component emits laser light. The fluorescent component has a phosphor. The phosphor is excited by laser light. The first illuminance homogenizer converts the laser light into laser light showing a spatially uniform light intensity distribution. The first illuminance homogenizer is disposed between the first light source component and the fluorescent component. The relay optical system guides laser light emitted from the first illuminance homogenizer to the fluorescent component. The relay optical system is disposed between the first illuminance homogenizer and the fluorescent component.
