The VELVET LED projector developed and manufactured by ZEISS is the only one in the world that has been created in every respect for astronomical displays in planetariums. It impresses not only with its enormous contrast ratio of 2,500,000 : 1, but also with its outstanding image quality.
As the only DLP projector on the market, VELVET achieves a contrast ratio comparable to ZEISS' fibre-optic star projection. VELVET LED provides an absolutely black image background. No grey background light brightens the night sky. Stars and objects shine on deep black.
DLP technology provides stability and ensures consistent colours and brightness for many years. Even after many thousands of hours of operation, a VELVET LED projector delivers excellent picture quality. The high contrast of the projector results in high color saturation. The eye perceives the high-contrast and color-intensive projection as particularly brilliant and pleasant. The new LED light sources provide an improved colour space compared to previous models.
Thanks to the absence of any backlighting by the VELVET projectors, there is no need for mechanical masks within or in front of the projection lenses, which is necessary with other projector technologies to reduce the visibility of channel blends. The transitions between the individual image channels are invisible with VELVET LED, the dome image is perfect.
