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|

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.
