High power 1064 nm lasers have become very popular for material processing. 1064 nm is invisible to the human eye but it is still necessary to have some method to visualize the beam. Coated paper Laser Viewing/Detection Cards block 100% of the beam and have a very low laser damage threshold so they can only be used with low power lasers.
The Precision Laser Scanning HI POWER – IR VIEWER, is a versatile visualization tool for assembling, aligning, testing and monitoring high power near IR laser systems. The glass has invisible nanocrystals that converts 900-1070 nm to green visible light. 3D visualization allows one to observe beam mode, size and shape. The laser damage threshold is > 100 Watts / mm2 CW and it passes > 80% of the beam so it can be left in place while running a system. TOUGH ENOUGH TO WORK WITH USP LASERS! The viewing glass size 20 x 20 x 2.5 mm overall. The handle allows the user to safely insert the viewing glass at any accessible beam location. This laser viewing GLASS is superior to laser viewing cards (AKA laser detection cards).
