Optoma BX-CTA17 0.65-0.75:1 Short-Throw Lens with Motorized Zoom

Ideal Use Cases

The Optoma BX-CTA17 is a motorized short throw lens designed for immersive installations where the projector must remain relatively close to the screen. Its 0.65-0.75:1 throw ratio provides a defined planning range for environments in which a longer projector-to-screen distance is unavailable or undesirable. Supported image sizes extend from 50 inches to 500 inches, giving system designers flexibility across installations of substantially different scales.

This lens is specifically identified for use with the Optoma ZU1300 and ZU110050 DuraCore laser projectors. It is therefore suited to projects already based on one of those compatible projector models or installations being designed around that equipment.

Why Choose This Model

The BX-CTA17 combines short throw optics with motorized zoom. That pairing distinguishes it from a fixed short throw solution by providing an adjustable throw ratio between 0.65:1 and 0.75:1. Installers can use this range when determining the appropriate relationship between projector placement and the intended image dimensions.

Its broad stated image-size range is another practical reason to select this model. The lens can produce images beginning at 50 inches and extending up to 500 inches when used within a compatible installation. This makes the BX-CTA17 relevant to both comparatively compact displays and expansive immersive presentations.

Installation and Integration

Planning should begin by confirming that the projector is an Optoma ZU1300 or ZU110050 DuraCore laser projector. The required image size, available throw distance, and specified 0.65-0.75:1 throw ratio should then be evaluated together before installation. Because the BX-CTA17 is a lens accessory rather than a complete projection system, image resolution, brightness, connectivity, power requirements, and other projector-level capabilities depend on the compatible projector being used.

The source information does not specify focus control, lens shift, lens memory, mounting details, physical dimensions, weight, included accessories, or warranty coverage. Those details should be confirmed separately when they are important to system design, mounting, transportation, or procurement.

Performance Highlights

The central performance specification is the short throw ratio of 0.65-0.75:1. This range is intended for installations requiring a short distance between the projector and screen. Motorized zoom provides the defining optical adjustment identified for this model, while the supported 50-inch to 500-inch image range accommodates a wide span of presentation sizes.

The lens is described as ideal for immersive installations, where image scale and projector positioning are often central design considerations. Its published throw-ratio range gives planners a concrete optical specification to use when assessing whether the lens matches the available installation space.

What Makes It Different

The BX-CTA17 is differentiated by the combination of three specific attributes: short throw positioning, motorized zoom, and support for images up to 500 inches. Rather than serving as a general-purpose lens with unspecified compatibility, it is directly associated with the Optoma ZU1300 and ZU110050 DuraCore laser projectors.

That clearly stated compatibility helps narrow equipment selection for supported Optoma projection systems. The adjustable 0.65-0.75:1 throw ratio also provides more placement latitude than a single fixed throw-ratio value, while remaining focused on short-distance projection applications.

Final Assessment

The Optoma BX-CTA17 is a purpose-built choice for compatible immersive projection installations that require short throw optics and motorized zoom. Its most important planning specifications are straightforward: a 0.65-0.75:1 throw ratio, an image-size range from 50 inches to 500 inches, and compatibility with the Optoma ZU1300 and ZU110050 DuraCore laser projectors.

For projects using one of those projector models, the BX-CTA17 offers a defined way to address limited projector-to-screen distance while retaining zoom adjustment. Final selection should be based on the intended image size, available placement distance, and confirmed compatibility with the complete projection system.
