Laser protection with laser safety curtains

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.

Certified laser blocking curtains – The “Orca” range – (black on one side and white on the other)

Lasermet laser-blocking Orca 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. This material is branded as Orca.

Tested in accordance with NFP 92-503 (Electrical Burner Test), the material is rated as M2. When irradiated with greater than 0.5 MW/m² it will emit a non-hazardous smoke and may glow, thus indicating that a stray beam is present.

Laser radiation protection times given by the material at various power densities are shown in the specifications below.

  Irradiated Area PEL (T3) 10s PEL (T2) 100s
Black or White Side 4mm² 3.9 MW/m² 2.2 MW/m²
  2000mm² 0.62 MW/m² 0.35 MW/m²

The top of the curtain has brass eyelets every 150 mm and the curtain is supplied with a stainless steel hook for connecting to a curtain track. The weight of the material is 1.3 kg/sq m. Heavy duty curtain tracks can be supplied for smooth operation. For applications where the curtain needs to be suspended below the fixing points, high-quality cubicle curtain track is available.
