powerdome®VELVET
Digital
Fulldome Projection
»True Black Projection Technology«
Carl Zeiss developed the perfect display solution for
fulldome projection with its powerdome®VELVET
system. The VELVET projector is based on the DLP ®
technology of Texas Instruments. It is the only DLP
projector on the market that deliveres absolute black
where black is in the image. The terrific contrast
ratio of 2,500,000 to 1, measured and confirmed by
different methods, is the highest contrast in digital
projection ever achieved. This contrast is comparable
with that of Carl Zeiss glass-fiber star projection.
The VELVET projectors are the best to match with
optical-mechanical star projections. Blends between
the image channels are invisible, even in most critical
projections. The high contrast also results in higher
saturated colors. The ultrahigh-contrast and colorful
projection is perceived by the eyes as extremly brilliant
and pleasant.
The projector employs the HDTV chip technology
and operates with 1600 picture lines. VELVET delivers a
high-definition, steady, brilliant image as known from
common DLP projectors, but with a completely black
background. Oblique installation positions are possible.
Lamp change is accomplished quickly and easily. The
design of the projector allows for different illuminating
systems depending on the optimal light output for specific
dome sizes and projector configurations.
To optimally satisfy requirements for dome projection,
Carl Zeiss equips its projectors with specially
designed, dedicated dome projection lenses only.

Fulldome Configurations
All powerdome®VELVET systems are based on multichannel
projections comprising a number of projectors
depending on the dome size and possible architectural
restraints. Projector locations and installation specifics
vary with different domes. The system is available for
flat (horizontal) domes as well as for theaters with
tilted domes.
In the case powerdome®VELVET will be used in
combination with an optical-mechanical planetarium
projector in the center of the dome, the panoramic
fields will be projected at an angle to avoid shadows
by the planetarium projector. VELVET Duo intended for
smaller domes consists of two projectors.
powerdome®ImageGenerator
The powerdome®IG is a multi-channel graphics cluster
for fulldome video, images and sound generation and
to merge opto-mechanical with digital planetarium
projections. The internal network serves for the control
of all computers and the projectors in synchronization.
All data for dome presentations (video, images, sound,
etc.) are stored on one Network Attached Storage
server (NAS), included in the network.
The graphical user interface and the planetarium
control panel allow for editing and presenting fulldome
shows and live presentations.
