Laser Safety Industries' laser curtains are designed to offer protection from direct and scattered lasers. Common laser applications are: Nd:YAG, Co2, ER:YAG (but are not limited to). The laser curtain material/fabric is attached by velcro to the frame. All curtains are made in a modular capacity with velcro on both ends enabling ease in adding on with a divider we offer as well (comes as part of larger systems). With the correct hardware, barriers can easily be converted to a curtain as well. For items that are designed to be wall attached, it comes with adhesive hook velcro; to install simply peel off and stick. Every curtain ships with the required laser‑safety sign(s) and specification label sewn directly into the panel. The frame is constructed of heavy-duty tubing with brushed finish to reduce specular reflection. Includes all hardware and instructions.*.
