Deliver larger images without locking your projector into a fixed room layout. The Optoma BX-CTA19 WUXGA lens gives integrators a 1.02-1.36:1 throw ratio, making it easier to match screen size and throw distance in demanding venues. Its 1.33x motorized zoom adds installation flexibility, while lens memory stores position settings for faster setup and repeatable alignment across presets. Purpose-built for the Optoma ZU1700, ZU1900, and ZU2200 Ultra Bright DuraCore laser projectors, this lens is suited to rental, staging, museum, and permanent installation environments where precision matters. The ability to project images up to 1,000 inches supports large-format experiences without sacrificing control over placement. For teams managing high-value AV deployments, the BX-CTA19 helps reduce adjustment time and keeps installs consistent from one venue to the next. When the room, screen, and projector position are already defined, the lens becomes the variable that protects image quality and installation efficiency. This model is built for professional projection systems where flexibility, repeatability, and scale justify the investment.
