Infrared radiation source, use of same, and a method for its manufacture

摘要

The invention relates to an infrared radiation source having a long, gas-tight casing tube made of quartz glass, and a heat conductor made of carbon which is situated in the casing tube, the heat conductor being electrically connected to at least two electrical contacts outside the casing tube and being situated at a distance from the casing tube by at least one spacer element and being centered therein, and is characterized in that the heat conductor is designed as a long strip and that the at least one spacer element is designed as a disk, whereby the disk has an opening for passing the heat conductor through, the disk at least partially fills the open cross section between the heat conductor and the casing tube, and the disk is made of carbon fiber-reinforced carbon (CFC).
