| 摘要 |
The invention relates to a "warm light reflector", which reflects infrared radiation and absorbs visible light. More specifically, a reflecting layer of, for example, gold carries a double layer of PbS, which is constructed of one smooth layer and of one fine-flocked layer of agglomerates. The disclosed warm light reflector finds particular application in infrared measurement technology, preferably in a passive infrared alarm generator. |
