Abstract
Sources of infra-red radiation have the property of emitting besides infra-red radiation also visible radiation which is considered to be disturbing in particular applications; in order to avoid it the visible portion of radiation is absorbed by means of a gas or a gas mixture so that only the infra-red radiation emerges from the source of infra-red radiation.
