Ultra-Short-Throw Versatility with Zero OffsetExpanding Choice for Immersive Spatial Performance Panasonic simplified ultra-short-throw lens and projector installation with innovative zero-offset zoom lenses for DLP™ projectors. The new ET-EMU100/ELU20 lenses bring the same flexible ultra-short-throw performance to select LCD laser projectors, allowing exhibition designers to choose the projection display technology that best suits their needs. These lenses make immersive and efficient LCD laser projection possible from short throw-distances in museums and other exhibition spaces by combining cost-efficient installation with vivid image quality and minimal shadowing. Short Throw-Distance Reduces Screen Shadows With a short 0.330-0.353:1 (WUXGA) throw-ratio, both lenses support a minimum projection distance of about 1.43 m (4.69 ft) for a 200-inch (16:10) image. Viewers can approach the screen without casting a shadow, making the lenses ideal for image projection onto passageway walls or other narrow spaces. Unobstructed Visibility with Zero Screen Offset Both lenses enable image reproduction with zero screen offset, eliminating the distracting gap between the top of the image and the ceiling or projector mounting surface. Position the image for seamless floor-to-ceiling image coverage over walls, or completely fill the available screen area without gaps. The mirrorless design also eliminates lens overhang. Mount the projector directly on the ceiling and avoid the hassle and expense of in-ceiling projector recessing to keep the screen clear in rooms with low ceilings. Uniform Brightness with Lens-Centered Rear-Projection Thanks to its mirrorless design, projectors can be set with lens positioned at screen center (rather than floor or ceiling) in rear-projection installations. Brightness is distributed more evenly and colors reproduced with greater uniformity from the center of the image out to the corners and edges. Flexibility Streamlines Installation Workflow Optical Zoom Helps Installers Work Fast Optical zoom enhances projector location flexibility. Installing a projector with fixed ultra-short-throw lens usually demands a high degree of precision, with installers sometimes having to remove, relocate, and reattach the projector several times before correctly placing the image. With ET-EMU100/ELU20, adjustment can be performed at the technician''s convenience after the projector is installed using powered optical zoom and V/H Lens Shift functions, saving time and labor and reducing overall cost of installation.
