Description

Laser Protection with Laser Safety Curtains

To ensure 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.

The Wolf material, formerly known as Blackcat, operates as a blackout curtain as well as a laser blocking curtain and is available in a grey colourway. It is ideal for use in laboratory and research establishments as well as manufacturing environments.

Mounting Options

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.

Production facilities using Class 1 lasers, which are Class 3B under service conditions, may require ceiling-mounted curtains to allow other work to continue safely in the same room during service.

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 Curtains

Lasermet’s laser blocking curtains can be motor powered up to a maximum run of 10m or 60kg.
