  • 149 mm (5.87") Square, 3 mm (0.12") Thick Viewing Screen
  • White Polystyrene Construction
  • 8-32 (M4) Tapped Metal Thread Insert for Post Mounting

Thorlabs' EDU-VS1(/M) Viewing Screen is ideal for observing interference patterns, spectra, and images. The screen, which measures 149 mm (5.87") square, is constructed from polystyrene. One side has a smooth matte finish, while the other has a slightly textured surface. These surface finishes were chosen to provide a diffuse, uniform reflection and to optimize the appearance of interference patterns and other images. Its white plastic construction allows bright images and beams to be observed even through the back of the screen.

This screen is equipped with an 8-32 (M4) tapped metal thread insert for post mounting; this feature allows it to be easily integrated into optomechanical setups.

Please note that this screen should not be used as a beam block or as any type of laser safety device. Its plastic construction results in a low damage threshold and makes it slightly translucent.

What is the minimum incident intensity for a red laser beam to be visible when reflecting from this surface ?

Response from Jeremy at Thorlabs: This is highly dependent on the person viewing the screen and the room condition. It's not something that we can specify.

For the EDU-VS1, it would be nice if one side had a giant bullseye on it. It would be useful for counting fringes, and it would allow you to make large beam or spot sizes for light sources.

Response from Bweh at Thorlabs USA: This is a good idea. I will follow-up by email to look into the possibility of a special quotation.
