VELVET 1600 brochure - Carl Zeiss Planetariums

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