Laservision has released laser viewing sheets, ideal for laser enclosures and rooms. They provide safe viewing of lasers from outside the nominal hazard zone. The laser viewing filters can be customised to facilitate most laser applications including doors, rooms, laser systems, and enclosures.
In one case study, a viewing window was required to block 1070nm laser light and block ultraviolet plasma radiation (blue light) resulting from a laser beam interacting with stainless steel. A high optical density of 8+ was needed.
A Laservision laser safety expert put two different pieces of acrylic together and mounted them into the window frame of the laser housing. The result was the ability to block the 1070nm laser and the ultraviolet plasma radiation at high OD levels in the same viewing window. The customer was very satisfied with this solution.
