 | Microscopic spherical glass beads embedded in a matt white base material. Due to their spherical shape, the glass beads reflect the majority of projected light back to its source. This results in a projected image which is significantly brighter than matt white, within an approximate 90 degree viewing cone. The superior on-axis reflectivity of glass beaded material makes it desirable for use with low luminance projection devices, including LCD platens and many LCD projectors. It should not be used with ceiling- or floor-mounted projectors. A glass beaded screen will tolerate a higher level of ambient light in the audience area. On axis gain of 2.5 and a recommended viewing cone of 90 degrees. Seamless in sizes up to 10' in height. 99" Diagonal, Aspect Ratio: 1:1, Screen Gain: 1, Matte White Surface, Angle of View: 70°, 70" x 70" Viewing Area Number of Reviews: 0 | Ratings:  | Best deal: $103 $103 - $103 from 1 stores. |
