The Christie 104-112101-01 is a standard zoom lens engineered for high-brightness Christie projectors utilizing 0.95-inch DLP technology, offering a versatile zoom range tailored to two common resolutions. It provides a 1.5-2:1 zoom for SXGA+ (1400x1050) projectors and a 1.4-1.8:1 zoom for HD (1920x1080) models, giving installers a practical degree of flexibility to adjust the image size without repositioning the projector. This capability is essential for fine-tuning the projection in boardrooms, lecture halls, command centers, and other fixed installations where the exact screen size or throw distance may require optimization after the initial mount. The lens is optically matched to preserve the projector's native resolution, light output, and color fidelity across the entire zoom range, ensuring a consistently sharp and bright image.

Constructed with precision glass elements within a durable metal barrel, the lens is built for long-term reliability in commercial environments. It includes manual zoom and focus controls, allowing for precise calibration during setup. The zoom ranges offered strike a balance between placement flexibility and maintaining a relatively large maximum aperture, which helps in preserving the projector's valuable lumen output. For system integrators working with compatible Christie SXGA+ or HD projectors, the 104-112101-01 provides a dependable and effective optical solution to achieve a perfectly sized image, adapting to the room's constraints while delivering the high-quality visual performance expected from professional-grade projection systems.
