The Christie ILS 1.8-2.6:1 CT 0.95" HD / 2-2.8:1 0.95" SXGA+ lens is a professional, high-performance zoom lens designed for compatibility with specific Christie DLP projectors. Engineered for large-venue and installation applications, it provides optical flexibility with a zoom ratio of 1.8-2.6:1 (or 2-2.8:1, as noted in its dual designation), allowing for precise adjustment of the projected image size without physically moving the projector. This capability is critical in fixed installations where the projector's placement is constrained by architecture or mounting structures, enabling a perfect fit to the screen from a predetermined throw distance. The lens is designed to accommodate both HD (1920x1200) and SXGA+ (1400x1050) native resolutions, making it versatile for a range of content types from high-definition video to detailed data graphics.

Optical performance is paramount, with the lens constructed from precision-ground glass elements featuring advanced multi-layer coatings to maximize light transmission, ensure edge-to-edge sharpness, and maintain accurate color fidelity. Its design minimizes geometric distortion, chromatic aberration, and light fall-off, which is essential for delivering a uniform, bright, and detailed image across large screens in demanding environments such as auditoriums, control rooms, simulation facilities, and premium home theaters. The lens is built to mate with Christie projectors via a specific mechanical mount and interface, ensuring secure attachment and precise optical alignment.

As a key component in a high-end projection system, this zoom lens provides integrators with the critical tool needed to optimize image quality and installation flexibility. By allowing fine-tuning of the image size post-installation, it reduces the need for costly structural adjustments and ensures the projector can be deployed in the most optimal location for thermal management, service access, and aesthetic considerations, ultimately contributing to a reliable and visually stunning large-format display solution.
