FAQ's

Q. Can you use ordinary blackout curtains to stop lasers?

A. No. Conventional curtain material is not good enough. It will not have been tested and it is usually made from a mesh or it will be woven. Either way it will have small gaps. It is also unsuitable material as the laser could easily burn through it, set fire to it, or simply pass straight through causing irreparable damage to skin or eyes. Lasermet's laser blocking material is tested and is certified to conform to the stated PEL (Permissible Exposure Limit) ratings listed in the respective tables.

Q. Can I use any black plastic material to stop the laser light?

A. No. Plastic material may reduce daylight but it not suitable for lasers. Laser protective material must be tested and certified as conforming to the laser safety standard BS EN IEC 60825-4.

Q. Which laser blocking material is suitable for sun blocking?

A. Any of the options are suitable for sun blocking: the “Orca” (Black and white range), the grey “Wolf” range or the grey “Rhino” range
