Laser Safety Windows

(Showing 27 of 27)

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.

All of our class 4 acrylic and glass laser windows meet or exceed the United Stated industry standard ANSI Z136.1 for the appropriate laser systems.  Our low level laser safety windows should only be used with low power lasers. For differences on Laser Safety Standards: ANSI vs CE - What's the Difference?ANSI Z136 and EN 207, see here

We are located in Minneapolis, Minnesota.  We are proud to be one of two approved laser safety window providers to the United States Army for "M1 Abrams" or the 3rd generation U.S. tank.
