Notice: We do not recommend the use of this particular Silver 3D screen material with retractable screen models. Due to the aluminized screen finish, there is a high probability of screen laddering, poor lay-flat characteristics and corner wrinkles in the image area. For that reason we recommend this screen for fixed applications only. |

Half gain is the standard that the
projection screen industry uses to measure the brightness performance of a
projection screen when the viewer is observing the screen from am extreme angle
or "off to the side".
A projection screen's peak brightness is when the viewer is directly in front and perpendicular to the center of the screen. This is referred to as Peak Gain at Zero Degrees Viewing Axis. As the viewer moves out to the side of the center of the screen axis, the brightness of the projected image will drop off. When the brightness drop off angle reaches 50 percent of peak gain, that determines the screen's half gain (or half brightness) viewing angle specification.
Example: Lets say a projector screen has a peak gain of 4 and it's output is 22 Foot Lamberts when directly in front of the screen at zero axis. Let's say the screen's half gain specification is at 52 degrees. That means that when a viewer is seated at 52 degrees of center screen, the viewer would observe half the brightness as a viewer that's seated directly in front of the screen - 11 Foot Lamberts - Gain of 2.
