Arrangement for restricting the transmission of electromagnetic radiation within a predetermined waveband, the arrangement comprising elements (1-3) in a light-transmitting material such as glass intended to be placed in the path of the radiation and which are positioned one after the other along that path, as well as enclosing in one or more spaces (4,5) between them gases characterised in that a number of different gases is used, said gases being selected with regard to their absorption capacity within one or more wavebands in such a way that they will essentially cover the predetermined waveband when used in combination with each other, said predetermined waveband being essentially within the waveband from 2 to 25 micrometers so that the transmission of thermal radiation is restricted while visible light is allowed to pass through. - (8pp) EPAB- EP-163639 B Arrangement for restricting the transmission of electromagnetic radiation within a predetermined waveband, the arrangement comprising elements (1-3) in a light-transmitting material such as glass intended to be placed in the path of the radiation and which are positioned one after the other along that path, as well as enclosing in one or more spaces (4,5) between them gases characterised in that a number of different gases is used, said gases being selected with regard to their absorption capacity within one or more wavebands in such a way that they will essentially cover the predetermined waveband when used in combination with each other, said predetermined waveband being essentially within the waveband from 2 to 25 micrometers so that the transmission of thermal radiation is restricted while visible light is allowed to pass through. USAB- US4800693 A The method is for manufacturing heat insulating window glass units which comprise two or more glass panes. - The method includes providing a gas mixture by choosing, among gases having a high absorption of electromagnetic radiation in the wave-length field of 2-25 micro, and having a transparency without noticeable negative influence on visible light, a first gas having one or more absorption bands for infra-red radiation and a second gas having one or more absorption bands for - infra-red ration. - The bands are positioned in the region at other positions than the bands of the first gas. - A third gas has one or more absorption for infra-red radiation, the bands being positioned in the field in other positions than the absorption bands of the first and second gases.
