Optoma BX-CTA18 0.84-1.02:1 Short-Throw Motorized Zoom Lens for Select Optoma Projectors

The Optoma BX-CTA18 is a short-throw lens featuring motorized zoom and motorized lens shift memory. Its 0.84-1.02:1 throw ratio and stated 50-inch to 1000-inch image-size range make it suitable for installations requiring a defined short-throw option across substantially different display sizes. The lens is designed for use with Optoma ZU1700, ZU1900, and ZU2200 Ultra Bright DuraCore laser projectors.

Ideal Use Cases

The BX-CTA18 is intended for both rental installations and permanent installations. In rental environments, its motorized zoom and lens shift memory provide useful adjustment flexibility when the lens is deployed in different venues or configurations. For permanent projects, its short-throw specification can be incorporated into the planned projector position and image size. Optoma specifically identifies entertainment and museum sectors as appropriate applications. Its broad stated image-size range supports everything from comparatively compact 50-inch presentations to installations producing images as large as 1000 inches, subject to the compatible projector and the installation layout.

Why Choose This Model

This model brings together three clearly defined installation capabilities: a short-throw optical design, motorized zoom, and motorized lens shift memory. The 0.84-1.02:1 throw-ratio range gives system designers and installers a concrete value for evaluating projector placement. Motorized zoom adds image-sizing flexibility within that range, while motorized lens shift memory supports saved lens positioning. These functions make the BX-CTA18 particularly relevant when installation flexibility and easier setup are priorities. Compatibility is also explicit: the lens is designed for the Optoma ZU1700, ZU1900, and ZU2200 projector models.

Installation and Integration

Integration begins with confirming that the projector is an Optoma ZU1700, ZU1900, or ZU2200 Ultra Bright DuraCore laser projector. The installation can then be planned around the lens’s 0.84-1.02:1 throw ratio and the intended image size. Optoma states that the BX-CTA18 can produce images from 50 inches up to 1000 inches, providing a wide planning range for entertainment, museum, rental, and permanent-install applications. Motorized zoom can be used as part of image-size setup, while motorized lens shift memory adds positioning flexibility. The supplied data does not specify lens-shift directions or adjustment ranges, so those values should not be assumed when planning the installation.

Performance Highlights

The central optical specification is the 0.84-1.02:1 throw ratio. This identifies the BX-CTA18 as a short-throw lens and provides a defined range for matching projector position to the required image. Its supported image-size span of 50 to 1000 inches is notable for installations that may vary greatly in scale. Motorized zoom complements that optical range by adding powered zoom adjustment. Motorized lens shift memory further expands the lens’s setup flexibility by combining lens-shift functionality with stored positioning capability. These features concern lens placement and adjustment; projector brightness and other image-performance characteristics are not specified for the lens itself.

What Makes It Different

The BX-CTA18 is distinguished by its combination of short-throw geometry and motorized installation functions. Rather than offering only a fixed short-throw configuration, it provides a 0.84-1.02:1 zoom range and motorized zoom control. Motorized lens shift memory adds another installation-oriented function, supporting applications in which saved lens positioning is valuable. The stated ability to produce images ranging from 50 inches to 1000 inches also gives the model relevance across very different project scales. Its application focus is equally specific: Optoma positions the lens for rental work and permanent installations, particularly within entertainment and museum environments.

Final Assessment

The Optoma BX-CTA18 is a focused lens option for compatible ZU1700, ZU1900, and ZU2200 Ultra Bright DuraCore laser projectors. It is best evaluated by its principal installation specifications: a 0.84-1.02:1 short-throw ratio, motorized zoom, motorized lens shift memory, and support for image sizes from 50 to 1000 inches. Those capabilities make it a strong match for the rental, entertainment, museum, and permanent-install applications identified by Optoma. Buyers should confirm projector compatibility and ensure that the stated throw-ratio range aligns with the planned projector position and image dimensions.
