Deliver the image size the venue demands without compromising placement flexibility. The BX-CTA21 motorized zoom lens is designed for Optoma ZU1700, ZU1900, and ZU2200 Ultra Bright DuraCore laser projectors, giving integrators a 1.5-2:1 throw ratio for large-scale projection planning. That range supports installations where projector position is constrained but image size still has to be exact. A 1.33x motorized zoom adds practical adjustment room during setup, while motorized focus and lens memory help reduce time spent on fine-tuning across repeated installs. For rental environments, that means faster changeovers. For permanent installations, it means more consistent results when the same projection geometry needs to be recalled and reproduced. This lens is a strong fit for entertainment venues, museums, and other spaces where projection quality is judged at scale. It is not a generic accessory; it is a precision component for systems that need controlled throw, repeatable setup, and dependable optical adjustment.
