The Christie 140-107109-01 is a high-performance long-range zoom lens engineered for Christie's DLP-based G and GS series projectors, designed for demanding applications where projector placement is highly constrained or requires significant throw distances. This lens offers an exceptionally versatile 2.9-5.50:1 zoom ratio, one of the widest available for its class, allowing system designers to precisely tailor image size from a single, fixed projector location over a broad range of installation spaces such as large auditoriums, houses of worship, or simulation domes. The optical formula utilizes precision-ground glass elements with advanced anti-reflective coatings to maximize light throughput and deliver high-resolution, high-contrast images with minimal distortion or chromatic aberration across the entire zoom range. This ensures that even when projecting to distant screens, fine details in high-resolution source material remain sharp and well-defined.

Built to professional standards, the lens features a robust, all-metal housing that ensures long-term mechanical stability and precise alignment under varying environmental conditions. It incorporates smooth, manual zoom and focus rings that provide fine, tactile control for on-site calibration. A key feature for complex installations is its support for electronic communication with the host projector; when connected to a compatible Christie model, the projector can store and recall specific lens settings (zoom, focus, shift) for different screen configurations or presentation modes, greatly simplifying operation in multi-use venues. The lens is part of Christie's comprehensive optics ecosystem, guaranteeing perfect mechanical fit, optimal optical performance, and full functionality with the projector's internal image calibration and warping systems.

The lens's substantial zoom range provides immense flexibility, allowing an integrator to use a single lens model for a variety of room sizes and screen dimensions without needing to physically move the projector. This makes it an invaluable tool for rental and staging companies, as well as for fixed installations where future reconfiguration is a possibility. Its design prioritizes consistent optical performance, ensuring uniform brightness and color fidelity from the center to the corners of the image at any throw setting. As a critical component in high-end projection systems, the Christie 140-107109-01 lens enables the creation of large-scale, impactful visual experiences where precision, reliability, and installation flexibility are paramount.
