Orca Laser Blocking CurtainsBlack on one side and white on the other

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.

Lasermet’s certified laser blocking curtains are used by the Acropolis Museum in Athens to enable work to be carried out on sculptures in-situ.
