Abstract
New Types of Screens.—Since the last report of the Committee, there have appeared several new developments in screens that deserve notice. Those that have come to our attention are the following: Screens of embossed material coated with ordinary white pigments have been introduced by several manufacturers. The indentations are about ⅛ inch square with a spherical contour, either convex or concave, and of about 1/16 inch relief. The purpose of this treatment is to obtain more uniform light distribution than is usually possible with an ordinary, flat, diffusing surface. Even diffusing screens with smooth surfaces frequently exhibit some loss of brightness at angles of 50 degrees or more from the screen normal, and also in some cases have a slight glossiness at the specular anglc which is undesirable because of the tendency to glare. The embossed screen tends partially to overcome these two deficiencies according to tests submitted by one manufacturer. However, it should be pointed out that a good flat screen is relatively free from such defects also
