Title:
THERMAL RADIANT LIGHT SOURCE
Document Type and Number:
Japanese Patent JP2021157961
Kind Code:
A
Abstract:
To provide a thermal radiation light source that can be installed with a substrate and a thermal radiation layer exposed to the atmosphere, has a large emissivity in a setting region set in a wavelength range of 8 μm or less, and can simplify the configuration.SOLUTION: A thermal radiation layer N and a substrate K formed of a cantal alloy that heats the thermal radiation layer N are laminated, and the thermal radiation layer N is configured in a state in which a radiation control unit Na having a MIM laminated portion M that positions a transparent oxide layer R for resonance formed of a transparent oxide between the substrate K and a platinum layer P and a transparent oxide layer Nb for radiation formed of transparent oxide are laminated in a form in which the radiation control unit Na and the transparent oxide layer Nb for radiation are located close to the substrate K in this order, and the thickness of the transparent oxide layer R for resonance is such that a set region set in a wavelength region of 8 μm or less is set as a resonance wavelength region.SELECTED DRAWING: Figure 1
