<P>PROBLEM TO BE SOLVED: To enable light of a desired spectrum to be emitted from a light emitter without bringing forth manufacturing cost hike with a simple structure. <P>SOLUTION: The light-emitting device is provided with a light source for emitting predetermined light, an emission-side bundle fiber with one end surface formed as an emission surface for transmitting light emitted from the light source to emit from the emission surface, a light-receiving side bundle fiber with one end surface formed as an incident surface and transmitting light transmitted from the emission-side bundle fiber and incident from the incident surface, a light emitter emitting light transmitted by the light-receiving side bundle fiber, and a spectral filter capable of moving to a direction crossing a direction with the emission surface and the incident surface arrayed between the emission surface of the emission-side bundle fiber and the incident surface of the light-receiving side bundle fiber, and selecting a wavelength in accordance with an incident position to transmit and emit the light of the selected wavelength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
