Motorized Short Throw Lens for UB Series WUXGA

Ideal Use Cases

The Optoma BX-CTA11 is designed for immersive installations that require a short distance between the projector and screen. Its short throw configuration makes it suited to projects where the selected Optoma projector must be positioned close to the display surface. The lens supports image sizes ranging from 50 inches to 1,000 inches, covering compact presentations as well as very large projected environments. It is intended for use with specific Optoma 4K UHD+ and Ultra Bright WUXGA projectors.

Why Choose This Model

The BX-CTA11 combines a motorized short throw design, zoom capability, and full lens memory in one compatible projector lens. Lens memory saves zoom, focus, and lens-shift positions and can quickly recall those settings when they are needed again. This is particularly useful for installations that use more than one stored image position or regularly return to an established configuration. The available 50- to 1,000-inch image-size range also gives system designers considerable flexibility when matching the projected image to the intended viewing surface.

Installation and Integration

Compatibility is clearly defined for integration planning. The BX-CTA11 is designed for the Optoma ZK1320 and ZK1120 4K UHD+ projectors. It is also designed for the Optoma ZU2200, ZU1900, and ZU1700 Ultra Bright WUXGA projectors. Selecting one of these supported models is essential when specifying the lens as part of a projection system.

Once installed with a compatible projector, zoom, focus, and lens-shift positions can be saved through the full lens-memory function. Those stored positions can then be recalled without rebuilding each saved arrangement from the beginning. The short throw format addresses installations where projector-to-screen distance is an important constraint, while the zoom function supports image-positioning adjustments within the lens system.

Performance Highlights

• Motorized short throw lens with zoom.
• Designed for immersive installations requiring a short projector-to-screen distance.
• Full lens memory saves zoom, focus, and lens-shift positions.
• Saved lens positions can be recalled quickly.
• Supports projected image sizes from 50 inches up to 1,000 inches.
• Compatible with specified Optoma 4K UHD+ and Ultra Bright WUXGA projector models.

These capabilities center on installation control rather than projector image generation. Resolution, brightness, contrast, and light-source performance are determined by the compatible projector selected for the system and are not specifications of the BX-CTA11 lens itself.

What Makes It Different

The defining combination is short throw placement, motorized operation, zoom, and comprehensive position memory. The memory feature covers three important lens adjustments: zoom, focus, and lens shift. By storing all three position types, the BX-CTA11 can support configurations that need to move between previously established lens arrangements. Its upper supported image size of 1,000 inches also distinguishes its intended scope, extending the lens from 50-inch images into expansive immersive applications.

The model is not presented as a universal projector lens. It has a named compatibility group spanning two Optoma 4K UHD+ projectors and three Optoma Ultra Bright WUXGA projectors. This focused compatibility makes it possible to identify the intended projector-and-lens combinations directly during system specification.

Final Assessment

The Optoma BX-CTA11 is a purpose-built motorized short throw zoom lens for compatible Optoma installation projectors. It is most relevant when an immersive layout requires the projector near the screen, when projected image requirements fall between 50 and 1,000 inches, or when zoom, focus, and lens-shift positions must be saved for quick recall. For systems based on the ZK1320, ZK1120, ZU2200, ZU1900, or ZU1700, it provides a clearly matched short throw lens option with full lens memory.
