Panasonic ET-ELU20 projection lens

Ultra-Short-Throw Versatility with Zero Offset
Deliver a 200-inch (16:10) image from about 1.43 m (4.69 ft) without screen offset or shadows for immersive performance in areas with limited installation space. Mirrorless design provides unobstructed visibility and supports screen-centered setup for
rear-projection.

Flexibility Streamlines Installation Workflow
Powered optical zoom and V/H Lens Shift* enhance projector location flexibility, saving time and effort by reducing the amount of installation precision required and enabling image adjustment after installation without having to relocate the projector.

Durability for
Peace of Mind
ET-ELU20’s heat- and scratch-resistant glass lens reduces focus aberration from fluctuating lens temperature, keeping images sharp.
ET-EMU100 supports AFO
(Active Focus Optimizer) to maintain crisp focus regardless of content brightness.

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.

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.

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.
