Zero offset UST lens for super high brightness solutionsThis UST lens, when used with an EB-L30000U Series projector, can be positioned extremely close to a wall or screen, while providing a brilliant, sharp display even in ambient lighting conditions. It offers an ideal solution for narrow spaces and rear-projection applications. Epson also offers a zero offset UST solution for all its interchangeable lens models ranging from 5,500 to 30,000 lumens.
