Ultra-Short-Throw Zoom Lenses for LCD Laser Projectors
Ultra-Short-Throw Versatility with Zero Offset
Expanding 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-Cantered Rear-Projection
Thanks to its mirrorless design, projectors can be set with lens positioned at screen centre (rather than floor or ceiling) in rear-projection installations. Brightness is distributed more evenly and colors reproduced with greater uniformity from the centre 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 labour and reducing overall cost of installation.
V/H Lens-Shift Supports Wide-Range Image Adjustment
Lens-Shift*1, range of V: +50 %, -20 %, H: ±20 % (ET-EMU100) and V: ±50 %, H: ±24 % (ET-ELU20) lets you move the image further than comparable lenses in four directions from Home position without needing to relocate the projector for unrivalled flexibility in post-installation adjustment. It increases projector location flexibility where ceiling fixtures or other obstructions restrict ideal placement. For convenience, powered zoom, lens-shift, and focus are performed via projector remote control or the free Panasonic Smart Projector Control*2 app.
Durability for Peace of Mind
Durable Design for Peace of Mind
ET-ELU20 employs a tough all-glass lens design that exhibits high resistance to heat and scratches. As well enhancing durability, glass lens elements reduce the incidence of focus aberration that can result from fluctuating operating temperature, helping preserve clear and sharp image quality. Secure stable and long-lasting imaging performance in combination with Panasonic’s highly reliable LCD laser projectors.
AFO (Active Focus Optimizer) Keeps Images Sharp
ET-EMU100 Ultra-Short-Throw Zoom Lens is compatible with the projector’s AFO (Active Focus Optimizer) function, which uses a sensor to continuously monitor temperature around the lens. In this way, the projector can maintain optimal focus even as lens temperature fluctuates with the brightness of the projected content, keeping images sharp at all times.
