The Christie 121-121105-01 is a standard zoom lens specifically engineered for use with the Christie DWU951-Q DLP projector. Its design provides a versatile 1.7-2.5:1 zoom ratio, offering installers a practical range of adjustment to fine-tune the image size without needing to reposition the projector physically. This flexibility is essential for overcoming common installation challenges in boardrooms, classrooms, and medium-sized venues, where the exact throw distance or screen size may require slight optimization after the initial mounting. The lens is optically matched to the projector's native WUXGA (1920x1200) resolution and light output characteristics, ensuring that image sharpness, brightness, and color fidelity are maintained consistently across the entire zoom range.

Constructed with precision glass elements housed in a durable metal barrel, the lens is built for reliable, long-term performance in commercial and educational environments. It includes straightforward manual controls for zoom and focus, allowing for precise calibration during the setup process. By providing a balanced zoom capability in a standard lens configuration, the Christie 121-121105-01 enables system integrators to achieve a perfectly sized and focused image from a more adaptable set of projector placement options. This lens serves as a practical and effective tool for ensuring optimal image quality in fixed installations where the Christie DWU951-Q projector is deployed.
