Create a larger image without giving up room depth. The Optoma BX-CTA15 short throw lens is built for installations where projector placement is constrained but image scale still matters. With a 0.75-0.95:1 throw ratio, it helps deliver immersive visuals in conference rooms, training spaces, and other environments where every foot of throw distance counts. A 1.26x motorized zoom adds practical installation flexibility, making it easier to fine-tune image size during setup. As an interchangeable lens, it supports a more tailored projection design rather than forcing a one-size-fits-all configuration. That matters in higher-value AV projects where alignment, coverage, and room geometry all affect the final result. This lens is designed for Optoma ZU1300, ZU1100, ZU1050, ZU860, ZU750, and ZU660e DuraCore laser projectors. For teams standardizing on Optoma’s high-brightness platform, BX-CTA15 extends placement options while preserving the performance expectations of a premium installation. It is a strong fit when the goal is to maximize image impact in compact or architecturally challenging spaces.
