Create large-format projection where space is limited. The Optoma BX-CTA11 short throw lens is designed for the ZU1700, ZU1900, and ZU2200 Ultra Bright DuraCore laser projectors, giving integrators the flexibility to place the projector closer to the screen while preserving image scale. Its 0.65-0.75:1 throw ratio supports immersive installations, themed environments, and other spaces where audience proximity and clean sightlines matter. A 1.15x motorized zoom, focus, and lens shift streamline setup and make fine adjustments faster during commissioning. Full lens memory helps save and recall lens positions, reducing time spent re-tuning the system after changes. For premium venues, that means fewer compromises during installation and more predictable results in the field. This lens is built for projects that demand precision, repeatability, and a polished final image. Whether you are designing an attraction, a simulation space, or a high-impact display environment, the BX-CTA11 helps the projector fit the room instead of forcing the room to fit the projector.
