Da-Lite Screen Company announces the expansion of its Polacoat line of rear projection optical coatings with the addition of DA-50 WA. Specifically designed for applications using high lumen projectors in conjunction with short throw lenses, this optical coating provides wider half-gain angles than traditional coatings, reducing the incidence of hot spotting. The DA-50 WA coating is unique in its ability to offer a high contrast tint to the projected image while maintaining wide viewing angles. This coating offers a 0.5 gain and a generous 60-degree half angle. It is available on the entire range of Da-Plex screens and with Da-Lite’s full range of factory framing options.
