Title:
熱輻射光源
Document Type and Number:
Japanese Patent JP6671654
Kind Code:
B2
Abstract:
A thermal emission source is provided that has a structure capable of suppressing deterioration of an optical assembly over time. The thermal emission source includes an optical assembly (1) having an optical structure in which a member made of a semiconductor has a refractive index distribution so as to resonate with light of a wavelength shorter than a wavelength that corresponds to an absorption edge corresponding to a band gap of the semiconductor. The optical assembly (1) includes a coating structure (30) with a coating material that differs from the semiconductor of refractive portions (10) and through which light of a wavelength included in a wavelength range from visible light to far infrared rays can be transmitted.
