  • Patent number: 8829889
    Abstract: A laser protective wall element for a housing in laser machining stations with which increased protection, in particular for the eyes of living beings, can be achieved. In a laser protective wall element for a housing at laser machining stations, an intermediate layer is present which has hot conductor properties. The intermediate layer can be formed between electrically conductive plate-like elements, an electrically conductive plate-like element and an electrically conductive coating or also two electrically conductive layers or can be arranged there. The electrically conductive plate-like elements, the coating and/or the layers are connected to an electrical voltage source as well as a measuring instrument which detects electrical current, electrical resistance and/or electrical capacity and whose measured signal change can be used for the condition monitoring of the laser protective wall element.
