Breathtaking video projection plus<br />
brilliant stars – an excellent match<br />
<strong>VELVET</strong> delivers much more than the<br />
perfectly black backdrop. Its projections<br />
fascinate by their outstanding<br />
definition and brilliant colors.<br />
For your stars to shine as beautiful<br />
as those on the natural sky, <strong>Carl</strong><br />
<strong>Zeiss</strong> recommends a combination of<br />
powerdome®<strong>VELVET</strong> with an opticalmechanical<br />
planetarium projector. No<br />
other projector can present the stars as<br />
tiny and yet as bright and brilliant as<br />
their natural counterparts.<br />
With powerdome you can control your<br />
digital image contents and your optical<br />
stars in perfect synchronism. And,<br />
thanks to the <strong>VELVET</strong> projector, nothing<br />
can dull the velvety black of your<br />
star-spangled night sky.<br />
High definition and stability with<br />
DLP chip technology<br />
<strong>VELVET</strong> with DLP ® technology offers<br />
decisive advantages over other video<br />
technologies. Arguably the greatest<br />
one is stability. Unlike other technologies,<br />
which suffer a noticeable drop<br />
of color saturation and homogeneity<br />
after a few thousand operating hours,<br />
<strong>VELVET</strong> lets you enjoy superb images<br />
much longer. Implementing many engineering<br />
and design solutions, <strong>Carl</strong> <strong>Zeiss</strong><br />
has designed this projector for a working<br />
life of at least ten years, and with<br />
low maintenance cost at that.<br />
In the <strong>VELVET</strong> projector, imaging<br />
devices with <strong>1600</strong> lines are at work<br />
(WQXGA resolution). Projectors with a<br />
single lamp provide very bright images<br />
in smaller domes, while projectors<br />
with a dual lamp set furnish impressive<br />
brightness in larger domes as well.<br />
Fulldome projection is always done<br />
with several projectors. <strong>VELVET</strong> Duo<br />
is designed for domes up to 12 m in<br />
diameter. It uses two projectors (channels)<br />
installed at the dome center or at<br />
the periphery. <strong>VELVET</strong> Systems with five<br />
or more channels will deliver fulldome<br />
images with resolutions of 4k or better.<br />
First-class projection lens<br />
Even the most advanced chip technology<br />
is of no use without an optical<br />
design that is tailored to dome<br />
projection. For <strong>VELVET</strong>, only the best is<br />
good enough: a <strong>Carl</strong> <strong>Zeiss</strong> lens of the<br />
DIGIGON series provides excellent imaging<br />
quality. The wide-angle lens with<br />
adjustable focal length permits flexible<br />
projector configurations, so that<br />
powerdome®<strong>VELVET</strong> can be adapted<br />
to any dome.<br />
Automatic projector calibration<br />
On request, <strong>Carl</strong> <strong>Zeiss</strong> fulldome systems<br />
come with camera-based projector calibration,<br />
a facility for the fully automatic<br />
adjustment of the image geometries<br />
of all channels. For further information,<br />
see our separate data sheet.<br />
