What is the purpose of screen gain in projection systems?

To measure the size of the projected image

To indicate how effectively a screen reflects light

The purpose of screen gain in projection systems is fundamentally to indicate how effectively a screen reflects light. It is a measure of the brightness of the projected image as perceived by the audience compared to the brightness of the light source. A screen with a gain of 1 reflects light equally in all directions, while screens with a gain greater than 1 reflect more light toward the audience, enhancing the perceived brightness of the image. This is particularly important in environments with ambient light, as a higher screen gain can help maintain image visibility and clarity.

In essence, selecting the right screen gain ensures that the projected image can be viewed optimally under specific conditions, making it crucial for achieving the desired visual performance in various settings.
