To ensure Class 4 and Class 3B laser beams do not escape from laser facilities, 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 Wolf material, formerly known as Blackcat, operates as a blackout screen as well as a laser-blocking screen and is available in a grey colourway. It is ideal for use in laboratory and research establishments as well as manufacturing environments.
Ideal for use with Class 3B and expanded Class 4 lasers, the laser protection times given by the material at various power densities are shown in the PEL specifications.
