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.
Laser curtains are designed as passive guards to enclose an area where 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.
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 Orca material operates as a blackout screen as well as a laser-blocking screen and is available in several colourways:
- White / Black
- Black on both sides
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.
MOTORISED LASER PROTECTION CURTAINS
Lasermet’s laser blocking curtains can be motor powered up to a maximum run of 10m or 60kg.
High Specification Safety
Lasermet laser-blocking Orca products are CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards).
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|
|4mm²||3.9 MW/m²||2.2 MW/m²|
|2000mm²||0.62 MW/m²||0.35 MW/m²|
