Optoma Technology BX-CTA23 Extra-Long-Throw Motorized Zoom Lens for Select Optoma Projectors

The Optoma BX-CTA23 is a motorized ultra long throw zoom lens created for projection setups that place substantial distance between the projector and screen. Its 1.8x zoom and stated image-size range from 50 inches to 500 inches make it a purpose-specific option for large-scale placement requirements. Optoma identifies it for distance installations and live venue entertainment and designs it for a defined group of Optoma projectors.

Ideal Use Cases

This lens is intended for environments where a projector cannot be positioned close to the screen. That makes it especially relevant to distance installations and live entertainment venues with long projector-to-screen spacing. The stated image-size range supports projects calling for anything from a 50-inch image to a 500-inch image, provided the selected projector and installation are configured for the intended result.

The BX-CTA23 is a lens rather than a complete projector. It is designed for use with the Optoma ZK1320 and ZK1120 4K UHD+ projectors and with the Optoma ZU2200, ZU1900, and ZU1700 Ultra Bright laser projectors. Buyers planning around any other projector should not infer compatibility from the supplied information.

Why Choose This Model

Choose the BX-CTA23 when the project requirements align with its published profile: ultra long throw placement, motorized zoom operation, 1.8x zoom, and image sizes spanning 50 to 500 inches. These are the core details that define the model and provide a practical basis for comparing it with other lens options.

Its compatibility list also makes selection direct for systems built around the ZK1320, ZK1120, ZU2200, ZU1900, or ZU1700. The lens gives owners and integrators working with these models a purpose-designed Optoma option for the long-distance applications described by the manufacturer.

Installation and Integration

Begin integration by confirming the projector model. The supported list comprises the Optoma ZK1320 and ZK1120 4K UHD+ projectors and the ZU2200, ZU1900, and ZU1700 Ultra Bright laser projectors. Because the lens is intended for installations with a long distance between the projector and screen, projector placement and target image size should be established as part of the system plan.

The available data does not provide a throw ratio, dimensions, weight, or lens-shift values. Those details should therefore be confirmed separately before mounting equipment or finalizing placement. The motorized zoom designation identifies powered zoom operation, while the source data does not specify focus control, lens memory, mounting options, or included accessories. The defined 50-to-500-inch image range remains the supplied sizing reference for integration.

Performance Highlights

At the center of the BX-CTA23 specification is its 1.8x zoom. Combined with the ultra long throw lens format, this addresses setups requiring extended projector-to-screen spacing. Its listed image range extends from 50 inches through 500 inches, covering a substantial span of display sizes for compatible installation plans.

Resolution, brightness, contrast, light-source life, and color performance are projector characteristics and are not specified for this lens. The ZK1320 and ZK1120 are identified as 4K UHD+ projectors, while the ZU2200, ZU1900, and ZU1700 are identified as Ultra Bright laser projectors. These descriptions establish the supported projector groups without assigning their display specifications to the lens itself.

What Makes It Different

What separates the BX-CTA23 is its specialized role. It is presented specifically for distance installations and live venue entertainment, where long projector-to-screen spacing is required. Its combination of an ultra long throw design, motorized 1.8x zoom, a 50-to-500-inch image range, and five explicitly identified compatible Optoma projectors gives buyers a clearly bounded application profile.

Final Assessment

The Optoma BX-CTA23 is suited to buyers who need a motorized ultra long throw zoom lens for a supported Optoma projector. For projects built around the ZK1320, ZK1120, ZU2200, ZU1900, or ZU1700, it offers 1.8x zoom and a stated image-size range of 50 to 500 inches. Its best fit is determined by projector compatibility and installation geometry: confirm the supported model, plan around the required image size, and verify any placement details not included in the available data. Based on the published information, it is a focused lens choice for long-distance Optoma projection systems and live venue applications.
