Panasonic ET-ELU20

Ultra-Short-Throw Lens

Panasonic simplified ultra-short-throw lens and projector installation with innovative zero-offset zoom lenses for DLP™ projectors. The new ET-ELU20 Panasonic projector lens brings 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.

This Panasonic ultra-short-throw lens makes immersive and efficient LCD laser front or rear projection possible from short throw distances in museums and other exhibition spaces, by combining cost-efficient installation with vivid image quality and minimal shadowing.

Note: Please check the Compatibility tab to make sure that this lens is compatible with your projector.

Key Features:

  • Ultra-Short-Throw Versatility with Zero Offset: Delivers a 200-inch (16:10) image from about 4.69 ft (1.43 m) 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.


Ultra-Short-Throw Versatility with Zero Offset

  • Short Throw Distance Reduces Screen Shadows: With a short 0.330–0.353:1 (WUXGA) throw-ratio, the ET-ELU20 supports a minimum projection distance of about 4.69 ft (1.43 m) 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: enables 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-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.
  • V/H Lens-Shift Supports Wide-Range Image Adjustment: Lens-shift* range of V: ±50 %, H: ±24 % lets you move the image further than comparable lenses in four directions from Home position without needing to relocate the projector for unrivaled 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 app.


Durability for Peace of Mind

  • Durable Design: 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.
