Fisheye lens making dome projection a reality

ET-D3LEF70

Key features

Compatible with high-brightness 3-chip DLP projectors up to 30,000 lm brightness
Supports WQXGA (4K+) ultra-high-resolution image projection
 Installation flexibility is supported by wide lens-shift (vertical: up to ± 37 %, horizontal: up to ± 17 %).
Adapted for dome-theater applications in planetariums, video domes at exhibitions, or theme-park attractions

A wide 91.5° viewing angle achieves maximum screen coverage with a single projector. 

Wide effective image circle supports high brightness and ultra-high-resolution projection

The ET-D3LEF70 supports WQXGA (4K+) ultra-high-resolution image projection at up to 30,000 lm brightness. Installation flexibility is supported by wide lens-shift (vertical: up to ± 37 %, horizontal: up to ± 17 %)*1.
*1 Vertical at WUXGA: up to ± 27 %, vertical with SXGA+: up to ± 25 %.

Flexible installation for dome projection

A wide 91.6-degree*2 viewing angle achieves maximum screen coverage with a single projector, where multiple projectors were previously required to cover the same area. The ET-D3LEF70 is adapted for dome-theater applications in planetariums, video domes at exhibitions, or theme-park attractions. Transport your audience into a lifelike environment to inspire an unparalleled sense of “being there.” When deployed in AR (Augmented Reality) and VR (Virtual Reality) applications, participants don’t need goggles as the lens produces dynamic picture realism across the entire screen circumference.

Accurate Image Plane Correction for focus consistency

The focus balance between the center and the periphery of the screen is adjustable, no matter how big or small the screen. Even at short throw distances, the lens corrects for optimal focusing of the outer areas of the image, and displays extraordinarily clear and vivid resolution across the whole screen.
