Infrared emitter having a layered structure

Martti Blomberg (Inventor), Hannu Kattellus (Inventor)

    Research output: PatentPatent


    A layered infrared emitter structure includes only semi-transparent metal layers, preferably one semi-transparent metal layer, and one or more dielectric layers on both sides of the semi-transparent metal layer. Further, an electric heating wiring is arranged in or between any of the dielectric layers to heat the semi-transparent metal layer up to a required infrared emission temperature, preferably to a temperature within a range from 400° C. to 1000° C.
