To ensure Class 4 and Class 3B laser beams do not escape from laser laboratory or medical facilities, including hospital theatres, certified laser blocking material should be installed. Ordinary curtains are rarely capable of stopping a laser beam and specially-designed certified laser blocking material must be used (Certified to IEC/EN 60825-4). Also production facilities using Class 1 lasers, which are Class 4 under service conditions, may require ceiling-mounted curtains to allow other work to continue safely in the same room during service.
To provide the necessary protection level, Lasermet's laser blocking curtains are ideal. They are designed as passive guards to enclose an area where Class 3B or Class 4 lasers are in use either to protect against accidental exposure to the laser beam or for long term blocking of laser radiation at lower power densities.
Motorised laser protection curtains
Lasermet's laser blocking curtains can be motorised up to a maximum run of 10 metres or 60kg.
Certified laser blocking curtains
All Lasermet laser-blocking products are CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards). Lasermet’s Laser-Blocking Curtains are made from the company's specially-developed laser-blocking material and are supplied ready-made as ceiling or wall-mounted curtains. The material is white on one side and black on the other side and will operate as a blackout screen as well as a laser-blocking screen.
Fireproof laser blocking curtains
The material is fireproof. When irradiated with greater than 0.5MW/m2 it will emit a non-hazardous smoke and may glow, thus indicating that a stray beam is present. Protection times given by the material at various power densities are shown in the specifications below.
The top of the curtain has brass eyelets every 150mm and the curtain is supplied with a stainless steel hook for connecting to a curtain track. The weight of the material is 1.3kg/sq m. Heavy duty curtain tracks can be supplied for smooth operation, and for applications where the curtain needs to be suspended below the fixing points, high-quality cubicle curtain track is available.
