    摘要: A light source device includes: a light source to emit first color light; a fluorescent member having a first region that includes a fluorescent body to convert at least a part of the first color light into second color light different from the first color light when irradiated with the first color light and a second region to transmit the first color light; a wave plate; a reflecting member to reflect the first color light transmitted through the wave plate; and an optical path separating element provided on an optical path between the light source and the fluorescent member and transmit one of the first color light emitted from the light source and reflected light of the first color light by the reflecting member, and reflect another one.

    摘要: An irradiation optical system includes a light source unit and an irradiation unit. The irradiation unit is configured to condense light from the light source unit onto an irradiated surface to irradiate the irradiated surface with the light. In the irradiation unit, a direction of an optical axis is a Z direction, two directions orthogonal to the optical axis and orthogonal to each other are an X direction and a Y direction, and a positive power in the X direction is set to be smaller than a positive power in the Y direction such that a condensing spot on an X-Y plane at a position where the light from the light source unit is condensed has an elliptical shape having the X direction as a major axis.
