Heavy-Duty Laser Blocking Screens
These screens are designed to block all lasers, including high power, multi-kilowatt materials processing lasers. There are two standard size screens, both of which are 1.98m high. The LBS-HD-8 is 2.35 m wide and the LBS-HD-4 is 1.185 m wide. The screens consist of a 50 mm thick sandwich of steel and a special lightweight laser-blocking material, with a white laminate finish on both sides. This is mounted on a powder-coated steel framework, with heavy-duty lockable castors. The screens can be wheeled into position and then kept there by locking the castors. They can be used to form a complete enclosure or part thereof.
Heavy-duty screens can be used to block lasers of all wavelengths. They offer protection to the following specifications:
|Irradiated Area ||PEL (T3) 10 s ||PEL (T2) 100 s |
|4mm ||61 MW/m2 ||34 MW/m2 |
|2000mm2 ||2.7 MW/m2 ||1.5 MW/m2 |
Where a production line uses a Class 4 laser for cutting and welding, it is impractical for the whole facility to observe Class 4 safety regulations. However, using complete enclosures can to turn the laser facility into a Class 1 system/environment.
