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 VELVET LED incorporates ZEISS optics of the highest quality, guaranteeing impressive image quality. This is why a 6k dome image generated with VELVET LED looks sharper and crisper than many an 8k image from other systems.
