Standard Laser-Blocking Screens
These are available in two standard size screens. The LBS-8 is 2.44 m (8 ft) wide and the LBS-4 is 1.22 m (4 ft) wide. Both are 1.92 m (6 ft 4 in) high, which is high enough to protect the eyes of anyone less than 6 ft 8 inches tall standing right up to the screen, while low enough to pass through a standard doorway. The screens can be made higher if desired.
Standard Laser-Blocking Screens use the same specially-designed laser blocking material used for laser blocking curtains and screens. The material is mounted on a black powder coated steel framework, supported on lockable castors.
The laser-blocking material, which seals to the floor, is white on one side and black on the other side. It will operate as a blackout screen as well as a laser-blocking screen. Both sides will block laser radiation but if the white side is used as the laser-blocking side a higher specification of blocking will be achieved, making it suitable for higher power lasers.
The material is fireproof. When irradiated with greater than 0.5 MW/m2 it will emit a non-hazardous smoke and may glow, thus providing a warning that a stray beam is present
Protection times given by the material at various power densities are shown in the specifications below.
Standard screens can be wheeled easily into position and then kept there by locking the castors. Multiple screens can be connected together using connecting pieces (LBS-C) in a straight line or at an angle up to 90 degrees. If four or more screens are used an enclosing rectangular enclosure can be constructed.
