Moderate viewing angle and the capacity to reflect light back along the projection axis make this surface the best choice for situations where there is a moderate amount of ambient light and the projector is placed on a table-top or in the same horizontal viewing plane as the audience. Gain 2.8 with a 30-degree viewing half angle.
