GLASSVu WT92
Rear Projection Screen

GlassVu WT92 is a white translucent screen with 92% transmittance of light projected onto its surface and haze measured at 93%. It is visible from a 120° angle to provide great off-center viewing. The high gain and extraordinary haze of the WT92 means that projected images are bright and powerful for easy viewing, while the white screen fits nicely into retail surroundings when not in use. The WT92 is an excellent all-round screen for most digital signage applications, including many higher ambient light settings other than those in direct sunlight.

In planning your installation, note that the opacity of the WT92 is such that while only a small percentage of projected light will pass through the screen, it may be possible to perceive a hot spot. This means that some attention may be required to position the projector where it will not create a hot spot for your viewer.

GlassVu Rear Projection Screens are offered in sizes ranging beginning at 80 inches diagonal (2032 millimeters) to around 32 feet across (10 meters). Larger screens are possible by combining multiple panels measuring 5 feet wide (1.524 meters) into a single display.

  • Digital Signage

transmittance

For polymer screens such as GlassVu, direct transmittance is the fraction of the incident intensity that does not deviate from the incident direction as light emerges on the other side of the screen. Restated, direct transmittance is the amount of projected light that passes through the screen and is not reflected or otherwise absorbed. When direct transmittance is greater than 90%, the screen is considered transparent.

haze

Haze is the percentage of transmitted light that in passing through the screen deviates from the incident beam by more than 2.5° from the normal incident beam. It is seen as the cloudy appearance of an otherwise transparent screen caused by light scattered from within the screen or from its surfaces.
