BX-CTA12 Motorized Semi Short Throw zoom lens

The Optoma BX-CTA12 is a motorized semi short throw zoom lens designed for large-scale, immersive projection environments. It supports image sizes from 50 inches to 1000 inches and includes full lens memory for saving and quickly recalling zoom, focus, and lens-shift positions. The lens is designed for selected Optoma 4K UHD+ and Ultra Bright WUXGA projectors.

Ideal Use Cases

The BX-CTA12 is ideal for immersive installations, including dome projection and high-performance golf simulation. Its semi short throw design suits applications where a large projected image is required and the selected projector must be positioned closer to the display area than a conventional long-throw configuration would allow.

Its supported image-size range extends from 50 inches to 1000 inches, allowing the lens to serve installations ranging from comparatively compact displays to expansive projection surfaces. This range is especially relevant for dome environments and simulation systems, where image scale is an important part of creating an immersive experience.

Why Choose This Model

The BX-CTA12 combines motorized lens operation, zoom capability, and full lens memory in one model. Lens memory saves zoom, focus, and lens-shift positions, then allows those settings to be recalled quickly. This is useful in installations that use defined lens configurations or need to return to saved image-position settings without rebuilding the complete setup each time.

The model is also purpose-designed for a specific group of Optoma projectors. It supports the Optoma ZK1320 and ZK1120 4K UHD+ projectors, along with the ZU2200, ZU1900, and ZU1700 Ultra Bright WUXGA projectors.

Installation and Integration

Projector compatibility should be confirmed before integrating the BX-CTA12 into a system. The lens is designed for the ZK1320, ZK1120, ZU2200, ZU1900, and ZU1700 models. The ZK1320 and ZK1120 are identified as 4K UHD+ projectors, while the ZU2200, ZU1900, and ZU1700 are identified as Ultra Bright WUXGA projectors.

During setup, the installation can use the lens’s zoom, focus, and lens-shift positioning to establish the required image. Once the desired positions have been set, full lens memory can save them for quick recall. The available projection-size range of 50 to 1000 inches gives system designers substantial latitude when matching the image to the intended projection surface.

Performance Highlights

The defining performance features of the BX-CTA12 are its semi short throw optical format, motorized operation, zoom capability, broad supported image-size range, and full lens memory. Together, these features address the positioning and setup demands of immersive projection applications.

Full lens memory retains zoom, focus, and lens-shift positions rather than limiting recall to a single setting. This coordinated position memory is particularly relevant when an installation relies on a known combination of image scale, focus, and placement. Saved positions can then be recalled quickly when that configuration is needed.

What Makes It Different

The BX-CTA12 is distinguished by the combination of a semi short throw design and image support extending up to 1000 inches. Its intended applications are clearly focused on immersive installations rather than general-purpose projection alone, with dome projection and high-performance golf simulation specifically identified as suitable uses.

Compatibility across two Optoma projector groups also gives the lens a defined role within Optoma’s installation lineup. It works with the ZK1320 and ZK1120 4K UHD+ models and three Ultra Bright WUXGA models: the ZU2200, ZU1900, and ZU1700.

Final Assessment

The Optoma BX-CTA12 is a specialized motorized semi short throw zoom lens for compatible Optoma projection systems. Its 50- to 1000-inch image-size support addresses a wide range of installation scales, while full lens memory preserves zoom, focus, and lens-shift positions for quick recall.

For dome projection, high-performance golf simulation, or another immersive installation using one of the specified Optoma projectors, the BX-CTA12 provides a focused combination of semi short throw optics, motorized functionality, position memory, and large-image capability.
