Abstract
Provided is an excitation light synthesizing unit capable of emitting, in one direction, excitation light incident from a plurality of difference directions. The excitation light synthesizing unit includes polarization splitter film (), first and second ¼ wavelength plates (and), and reflection member (). Polarization splitter film () transmits excitation light that is P-polarized light while reflecting excitation light that is S-polarized light. First and second ¼ wavelength plates (and) are arranged on the path along which first excitation light (L), which is directed toward polarization splitter film (), travels. Reflection member () disposed between first and second ¼ wavelength plates (and). Reflection member () reflects second excitation light (L) incident via polarization splitter film () toward polarization splitter film (). Reflection member () includes hole () formed to pass first excitation light (L).
