  • Introduction

    Highest sharpness and contrast with brilliant colors

    With VELVET LED, ZEISS offers the only video projector in the world with an absolutely black background based on the DLP® technology from Texas Instruments. VELVET LED was developed by ZEISS. The projector not only impresses with its enormous contrast of 2,500,00 to 1, but also by its outstanding image quality. The projector provides an absolutely black image background with invisible blends between the image channels. The new semiconductor light sources expand the color space, have a nominal service life of 20,000 hours and are immediately ready for operation when switched on.

    Outstanding image quality

    The VELVET LED features ZEISS optics of the highest grade, which guarantee impressive images. That is why a 6k dome picture projected with VELVET LED may well look crisper than many an 8k image produced by other systems. Making you forget blurs, visible edge blends, and brightness and color deviations between channels, VELVET LED projectors offer a projection quality for astronomical and related contents that no standard projector can deliver.

  • Features

    Designed Specifically for Planetariums

    • DLP technology and ZEISS optics for pin-sharp pixels and excellent pixel contrast

    • Absolutely black image background, entailing higher color brilliance

    • high resolution for images particularly rich in detail: true pixels, no pixel shift

    • Colors of higher saturation; pure white thanks to LED lighting

    • Result: Color rendition fidelity visibly improved compared to previous models

    • Impressive brightness for all planetarium applications

    • 30-bit color depth for stepless color gradients without banding

    • Invisible transitions between image channels (perfect edge blends)

    • Edge blend computation without gray level losses

    • No mechanical masks, for best possible edge blending quality

    • Reduced overlap zone between channels, resulting in better pixel utilization

    • Color stability and homogeneity virtually throughout the operating life

    • Higher brightness stability compared to lamp projectors

    • Specially corrected ZEISS objectives, which take the curvature of the projection screen into account

    • Optimized image quality thanks to optics of extremely high transmission and color purity

    • Virtually non-vignetted projection

    • Transfer of the imager matrix with minimum modulation losses, resulting in homogeneous, pixel-precise imaging without distortions and chromatic aberrations

    • Enclosed light engine for long service-free operation

    • No stray light in the projector, nor in the objective

    • Lightproof – no light exiting between housing components

    • Improved cooling permits noise-reduced operation

    • Robust mounting frames

    • Easy adjustment, lower failure rate compared to projectors with color wheel

    • Availability extended by about 40% thanks to LED light source (no warm-up, can be switched on or off any time)

    • Extremely long rated life of ten and or more years

    • Fast, cost-effective remote maintenance

    • Service guaranteed for at least ten years

    • Matched projector and software configuration from a single source

    • Manifold configurations possible, also for off-center projection

    • Suitable for stereo projection (active 3D – 120 Hz)

    • Full-scale calibration facilities (geometry, brightness, colors)

    • Markedly reduced overall operating costs
