Infrasolid’s infrared radiation sources are pulsable thermal emitters with a near black-body emittance. Based on a patented nanotechnology and a patented emitter set-up made of a high-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface offer numerous advantages in many applications. The high, broadband emissivity results in a broadband and highly efficient emission of infrared radiation. By adapting the nanostructured surface, the emission spectrum can be influenced and adapted to specific applications. In this way, energy consumption can be reduced by not generating radiation in the unneeded wavelength ranges. The unique and patented manufacturing process allows the flexible production of different emitter area geometries and, therefore, an easy adaptation to customer-specific applications. The infrared radiators are available in an open version and in a hermetic housing. The outstanding properties and the high miniaturization potential enable smaller, more powerful, and more effcient analysis and gas measurement devices. Growing environmental and safety awareness as well as increasing automation are creating a growing demand for reliable gas sensors and offering a wide range of application scenarios for this new infrared emitter technology, also in the consumer sector.
