Thorlabs' Post-Mountable Polystyrene Viewing Screens are ideal for observing interference patterns, spectra, and images. The screens are available in small (75 mm x 75 mm) or large (150 mm x 150 mm) sizes. Both screens are 3.0 mm (0.12") thick. 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. Their white plastic construction allows bright images and beams to be observed even through the back of the screens. Each screen includes one crosshair sticker that can be used for beam alignment.
These screens are equipped with an 8-32 (M4) tapped metal thread insert for post mounting; this feature allows them to be easily integrated into optomechanical setups.
Please note that the screens should not be used as a beam block or as any type of laser safety device. Their plastic construction results in a low damage threshold and makes them slightly translucent.
