光学装置および光学装置の製造方法
Document Type and Number:
Japanese Patent JP7357082
Kind Code:
B2
Abstract:
An optical device includes a metal reflective layer substantially made of a metal material, a first light transmissive layer disposed on the metal reflective layer, an optical multilayer reflective film disposed on the first light transmissive layer and including a plurality of sublayers stacked on each other and having different refractive indexes, and a wavelength converting layer disposed on the optical multilayer reflective film and containing a fluorescent material capable of absorbing incident excitation light and generating fluorescent light having a lower energy. The wavelength converting layer is capable of generating mixed light containing the excitation light and the fluorescent light in response to irradiation with the excitation light.
