Abstract
An infrared light radiation device includes a radiation unit and a condenser. The radiation unit includes a heater and a metamaterial structure. The metamaterial structure is able to radiate, when heat energy is input from the heater, infrared light having a peak wavelength of a non-Planck distribution. The condenser includes at least one condensing lens that concentrates and transmits toward outside the infrared light radiated from the radiation unit.
Claims6
An infrared light radiation device comprising:
- a radiation unit that includes
- a heater, and
- a metamaterial structure that is able to radiate, when heat energy is input from the heater, infrared light having a peak wavelength of a non-Planck distribution;
- and
- a condenser that includes at least one condensing lens that concentrates transmits toward outside the infrared light radiated from the radiation unit;
- and
- a reflector that reflects to the condenser the infrared light radiated from the radiation unit;
- wherein the metamaterial structure includes
- a first metamaterial structure that radiates the infrared light from a first radiation surface, and
- a second metamaterial structure that radiates the infrared light from a second radiation surface,
- wherein the first metamaterial structure, the heater, and the second metamaterial structure are arranged in this order in a direction perpendicular to a direction in which the radiation unit and the condenser are arranged, and
- wherein the first metamaterial structure and the second metamaterial structure are interposed between one and another sides of the reflector.
