  • Devices for absorbing infrared radiation comprising a quasi-crystalline element
    Patent number: 6589370
    Abstract: The invention relates to a device that absorbs infra-red radiation, which comprises as a coupler element for the infra-red radiation, an element made of a quasi-crystalline alloy, made up of one or more quasi-crystalline phases, the volume of which represents at least 40% by volume of the quasi-crystalline alloy, a quasi-crystalline phase being either a quasi-crystalline phase in the strict sense, or an approximating phase or an approximating compound. The invention is used in applications such as in a bolometer, infra-red filter, thermocouple, or hot plate.
