The SHARP NEC XP-40ZL is a short-throw zoom lens designed for specific SHARP NEC projectors. This lens offers a throw ratio range of 0.79-1.14, making it suitable for environments where projection distance is limited but a large image is required. It includes lens shift capabilities, providing flexibility in projector placement relative to the screen. It addresses the challenge of achieving large, clear images in confined spaces by enabling projectors to be positioned closer to the screen than standard lenses. This lens is compatible with the XP-V731U, XP-V801U, XP-A824U, XP-A104U, and XP-A4U projector models, ensuring proper integration and performance within existing or new SHARP NEC projection systems.
