The Barco R9862030 lens is a professional-grade optical accessory engineered to work with compatible Barco large-venue projectors (likely the HDX, HDF, or similar high-lumen series). It provides two specified throw ratios depending on the output resolution of the projector used: 2.6-4.1:1 for HD (1920x1080) systems and 2.8-4.5:1 for SXGA+ (1400x1050) systems. This wide zoom range offers significant installation flexibility, allowing the projector to be placed at varying distances from the screen. The lens features high-end optics designed to maintain exceptional brightness, clarity, and color integrity even over long distances, which is essential for professional applications like live events, control rooms, and large screen installations. The zoom and focus functions are typically motorized, enabling precise remote adjustment during the setup process.
