Aluminum Protective Screens




  • Anodized Aluminum Barriers
  • Finished to Ensure Consistently High Diffusion
  • Four Size Options

Thorlabs' Aluminum Protective Screens prevent stray or unwanted light from entering or exiting an experimental setup. The aluminum is treated prior to anodization to create a homogeneously diffusive surface that is superior to patterned, textured surfaces, which scatter light unevenly.

 


Aluminum Protective Screens

 

  • Bead Blasted Anodized Aluminum Barriers
  • Three Sizes Available:
    • 8" x 6" (203 mm x 152 mm)
    • 12" x 12" (305 mm x 305 mm)
    • 24" x 12" (610 mm x 305 mm)

Thorlabs' Aluminum Protective Screens prevent stray or unwanted light from entering or exiting an experimental setup. The aluminum is bead blasted prior to anodization to create a homogeneously diffusive surface. With walls just 0.08" (2 mm) thick and bases that are 0.79" (20 mm) wide, these compact, lightweight screens are easily integrated into a laser setup.

The base of each screen contains several slotted mounting holes that are each 2" (50.8 mm) long, providing flexible mounting options. They are designed for use with 1/4"-20 or M6 cap screws. The TPS4 additionally contains a centered through hole designed for 8-32 or M4 cap screws, allowing the TPS4 to be mounted to a post.

 Magnetic Laser Safety Screen

 

  • Two Magnets on Underside Provide Holding Force
  • Slotted Mounting Hole for Non-Magnetic Surfaces
  • Laser Engraved with Target Grid
  • Homogeneously Diffusive Anodized Coating
  • Damage Threshold: >350 J/cm2 (1064 nm, 20 ns, 20 Hz, Ø1.14 mm)
  • Size: 7.87" x 2.95" (200.0 mm x 75.0 mm), Footprint: 2.95" x 1.38" (75.0 mm x 35.0 mm)

Our TPSM1(/M) Magnetic Laser Safety Screen is laser engraved on one side with a 1/2" or 10 mm target grid for rough laser alignment, while the other side is blank to provide a complete beam blocking option. The base of the screen is fitted with a pair of powerful magnets that hold the screen to magnetic work surfaces and provide flexibility of movement. A through hole is also provided to allow the screen to be tightened down using a cap screw for more permanent placement or for use in non-magnetic applications. The compact size of the screen allows it to fit into small gaps between your accessories, enabling easy integration into a laser setup. This screen is constructed from bead-blasted aluminum to remove any sharp edges, then anodized to create a homogeneously diffusive surface. 

Please note: Due to the presence of strong magnets, these laser screens should not be used in the vicinity of pacemakers, credit cards, or other devices affected by magnetic fields.
