Abstract
A thermal emitter device, including a thermal emitting membrane including a surface, wherein the membrane can be heated to a thermal emission temperature so that the surface radiates IR or visible light, wherein the emissivity of the surface is lower than 0.7. A lens includes a surface facing the surface of the membrane, and has a reflectivity normal to the lens surface included in the range 4% to 40%, to partially reflect the radiated IR or visible light, wherein the distance between the lens surface and the surface is equal or lower than L/4, where L is a major length of the membrane. A part of the IR or visible light reflected by the lens is reabsorbed by the membrane, and another part of the IR or visible light reflected by the lens is reflected by the membrane toward the lens, having therefore another chance to go through the lens.
