Laser protection with Orcatina Laser Safety Curtains

The Orcatina laser blocking curtain is shown here on the right in black while conventional material (in this case blue) is on the left.

Orcatina laser safety curtains are Lasermet’s answer to providing laser protection for personnel by using a compact and neat curtain system that uses a pantograph structure in the folding mechanism. Known also as concertina style or accordian style curtains, the Orcatina curtains have two separate materials – one is the laser blocking material and the other is fabric that can be used to look smart and help with sound insulation.

This guarantees a continuous and consistent pattern of folds that can be used not only to safeguard against laser radiation, but to act as a room separator and to minimise the sounds from the neighbouring partitioned room.  The folded laser blocking curtains use the minimum of space once drawn back.

There are no floor rails as the curtains are supported solely by the upper rail structure mounted to the ceiling. The curtains are made from Lasermet’s Orca black and white laser blocking material which is used on Lasermet’s conventional laser blocking curtains and laser blocking roller blinds with the consistent PEL ratings for different power densities and timescales. They are, of course, certified to BS EN IEC 60825-4.

To provide the necessary protection level, Lasermet’s Orcatina laser blocking curtains are designed as passive guards to enclose an area where Class 3B or Class 4 lasers are used, either to protect against accidental exposure to the laser beam, or for long term blocking of laser radiation at lower power densities.
