How to Properly Position Laser Curtains in Your Facility

30 August 2019

Laser Blocking Curtains used in a laboratoryLaser curtains are used as a passive guard to enclose an area where Class 3B or Class 4 lasers are in use.  They protect against accidental exposure to the laser beam or for long term blocking of laser radiation at lower power densities.

We offer many types of barriers depending on the power of your laser.  We offer protection from Class 2 to Class 4.  In addition, we also offer CE marked curtains.  Finding the right barrier is easy.  Simply send us the specs for your laser and we can determine which barrier will work best for you.

Curtains don’t have to be used on tracks.  For smaller windows, curtains are made with Velcro sewn onto the edges. Then, you can attached the curtain to Velcro around the window.  Or, if you have a metal frame, magnets can be sewn into the edges.  This makes for easy placement and removal of the fabric.  This is the best option for an operating room door.  It’s quick, and easy to clean.

If you have a room that needs to be divided with a laser curtain, a curtain track would be the best option. Tracks can be mounted to ceilings and walls.  Floor mounted curtains are also available.

Production facilities using Class 1 lasers, which are Class 4 under service conditions, may require ceiling-mounted curtains to allow other work to continue safely in the same room during service.

Need curtains for a cleanroom?  We now offer fabric for cleanrooms – Up to Class 7.  It is cleanroom applicable, anti-bacterial, and has ESD premium protection.  Need a sample?  No problem, just let us know.

Need portable curtains?  Laser curtains can be placed in a frame with castors.  This makes it easy to move if you need it to be portable.  To section off a corner, you would need 2 framed barriers.  Custom sizes are available.
