Panasonic announces details of three new zero offset lenses for its range of 1-Chip and 3-Chip DLP projectors, including a world first UST lens to feature a powered optical zoom.
The range comprises the ET-DLE020 ultra-short throw zoom lens, the industry’s first featuring powered optical zoom, designed to fit all Panasonic 1-Chip DLP projectors. In addition, two lenses have been developed for Panasonic’s high brightness 3-Chip DLP laser projectors. The ET-D3LEW200 short-throw zoom lens and ET-D3LEU100 ultra-short throw lens are suitable for 20,000 and 30,000-lumen, WUXGA and 4K+ projectors.
The lenses for 3-chip DLPTM projectors feature a novel L-shaped design which eliminates the issue of screen offset, solving problems associated with image projection from short distances in limited spaces, especially in venues with low ceilings. By virtue of the design, the issue of the visual obstruction caused by some UST lenses that protrude from the projector, has also been eliminated. This also means the projectors can be stacked for redundancy or for multiplying the brightness on a single surface.
Set for release in September 2019, all three lenses have full range powered lens shift to enable greater adjustment flexibility, while the two models with powered zoom simplify image size and position adjustment after installation.
The ET-D3LEU100 ultra-short throw lens supports a 0.37:1 (4K+) throw ratio for large screen projection from very short distances, while the ET-D3LEW200 short-throw zoom lens features powered zoom with a 0.70–0.91:1 (4K+) throw ratio. Both eliminate offset without increasing projection distance. Powered ±59 % (Vertical) lens shift enables wide ranging adjustments after the projector has been installed. Panasonic’s lens memory function further expedites calibration.
The ET-DLE020 ultra-short throw zoom lens supports a 0.28–0.30:1 (WUXGA) throw ratio and powered lens shift of +50 % to -16 % (V) and +23 % to -10 % (H) to enhance freedom of screen adjustment in all four directions.
