    • TPSM2(/M): 11.81" x 2.95" (300.0 mm x 75.0 mm), Footprint: 2.95" x 1.38" (75.0 mm x 35.0 mm)
  • Two Magnets on Underside Provide Holding Force
  • Slotted Mounting Hole for Non-Magnetic Surfaces
  • Homogeneously Diffusive Anodized Coating
  • Damage Threshold: >350 J/cm2 (1064 nm, 20 ns, 20 Hz, Ø1.14 mm)

Our Magnetic Laser Safety Screens are laser engraved on one side with a 1/2" (10 mm for metric versions) 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 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, which is 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.

I have an improvement suggestion for the family of vertical rulers like BHM1 etc. It would be nice if both sides had the scales, but the back side had the metric and imperial scales switched. In other words, when you look on one face, it's imperial scale on the left, but when you look on the other face, it's metric scale on the left. This would be very useful in crowded optical setups, when it's inconvenient or impossible to set up the ruler to use the desired scale. It would also be nice to have an option to buy a vertical ruler (like BHM1) that has both magnetic feet on the same side (like TPSM1 does). I often need to take height measurements inside a laser, where floor space is very limited, and feet on opposite sides make it very difficult sometimes. Such ruler, with both scales on both sides, like described in the first paragraph, would be very nice to have, indeed.

Dear Sir or Madam, we are using the alignment screens in our laser lab and would suggest that the magnet in the base do not need to be so strong. If you is not careful the screen can easily snap onto the optical table.

Response from Mike at Thorlabs: The laser safety screens are designed to be used on steel optical tables, we used magnets rather than screw slots in order to give the customer greater flexibility when placing the screen. The magnets are strong in order to help prevent the safety screen from being knocked and moving easily, which could be a potential hazard if you are using the screen to block a beam.
