GLASSVu CT88
Rear Projection Screen

GlassVu CT88 is a clear screen with 88% transmittance of light projected onto its surface and haze measured at 33.5%. It is visible from a 150° angle to provide extraordinary off-center viewing.

The near-transparency of the CT88 allows for content that can create the illusion of floating images moving across the screen or capture a rich landscape for projections onto a storefront window where ambient light is not a challenge. The CT88 provides for excellent after-hours viewing in display windows where there is otherwise a requirement for transparency during business hours.

In planning your installation, note that the nature of a transparent screen is that it will allow a significant percentage of projected light to pass through the screen. This means that special attention is 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.

Recommended uses:

  • Digital Signage
  • Art Installations
  • Floating Images

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.
