The Christie 140-115108-XX is a precision-engineered, short-throw zoom lens designed specifically for integration with Christie's high-brightness, three-chip DLP projectors, such as those in the Griffyn, HS, or D4K series. This lens model offers a versatile zoom range with a throw ratio from 1.02:1 to 1.36:1, enabling the projection of very large images from an exceptionally short distance. This capability is critical for installations in spaces with limited depth, such as corporate lobbies, command and control centers, museums, and large-venue auditoriums where the projector must be mounted close to the screen or display surface to avoid sightline issues and maintain a clean aesthetic. The optical design is meticulously calculated to meet the demanding resolution and light-output requirements of professional-grade projectors, ensuring edge-to-edge sharpness, minimal distortion, and high contrast even when projecting 4K or high-brightness content.

Constructed to the rigorous standards of the cinema and large-venue market, the lens employs multiple high-quality glass elements with specialized multi-coatings to maximize light transmission, reduce internal reflections, and maintain color fidelity. The housing is a robust, machined assembly that provides precise alignment and stability, with integrated mechanisms for manual zoom, focus, and lens shift. The lens shift functionality, both vertical and horizontal, is a crucial feature that allows installers to fine-tune the image position without physically moving the projector, facilitating perfect alignment with complex screen geometries or blend edges in multi-projector setups. Thermal management is integrated into the design to handle the significant heat generated by high-lumen light engines without affecting optical performance.

Installation requires a compatible Christie projector with a motorized lens mount system, allowing for remote adjustment and storage of lens settings. This lens is part of Christie's comprehensive lens portfolio, giving system designers the flexibility to select the exact throw ratio needed for a venue. For integrators tasked with deploying a visually immersive experience in a constrained space, the Christie 140-115108-XX short zoom lens is an essential optical tool that transforms the projector's raw output into a perfectly sized, positioned, and focused image of reference quality.
