Laser Safety Windows

(Showing 28 of 28)

A laser safety window is used to protect against lasers while still enabling users to see through them.  Laser safety windows are commonly used in laboratories, the U.S. military and other defense agencies, manufacturing facilities, and space exploration.  We provide sizing options and many other variations.  Please drop us a quick note here and a laser safety expert will reach out to you within an hour to discuss details.

  • Class 4 Lasers refer to either: Class 4 Acrylic Laser Windows | Glass Laser Windows (Squares | Rectangles | Circles | Custom Sizing)
  • For only our low power laser safety windows, commonly referred to as "laser shielding" or "laser shield acrylic sheets", please check out our low power laser safety windows.  Please note that these should never be used with class 4 lasers. Please consult your Laser Safety Officer or just  give us a call.

For more information, visit our buyer’s guide for laser safety windows here.  We have also prepared a whiteboard videos of a buyer's guidehow to read optical density notation, and more information about us directly below.  Different acrylic laser safety sheets are applicable to different lasers.  

Warning: Laser safety windows are not intended to replace laser protective glasses.

     

Different acrylic laser safety sheets are applicable to different lasers.  Warning: Please note, laser windows are not intended to replace laser protective glasses.
