Abstract: A light source device includes an excitation light source which generates excitation light, a fluorescent member containing a fluorescent substance which absorbs the excitation light to generate fluorescence, an emitting side optical member which is provided on an emitting end face of the fluorescent member, and a reflector which is provided on the side surface of the fluorescent member. The reflector has an optical property of reflecting the excitation light and the fluorescence. The emitting side optical member has an optical property of reflecting the excitation light and transmitting the fluorescence.

Abstract: An optical encoder includes a scale which is installed on one member of which, displacement is detected, and a detecting head which is installed on the other member which moves relatively with respect to the one member, and is disposed facing the scale. A predetermined optical pattern in a direction of relative movement is provided, and the detecting head includes a light emitting section which irradiates a predetermined light on the scale, a light detecting section which includes a light receiving surface which receives light through the optical pattern, which is irradiated on the scale from the light emitting section, and which detects light distribution formed on the light receiving surface, a first light transmitting member which is disposed in an optical path between the light emitting section and the scale, and a second light transmitting member which is disposed in an optical path between the scale and the light detecting section. The optical encoder further includes a stray-light reduction element which is interposed between a surface of the first light transmitting member and a surface of the second light transmitting member, and which reduces stray light which does not contribute to signal detection.
