The Christie 140-109101-02 is a high-quality, professional-grade zoom lens designed specifically for integration with compatible Christie DLP projection platforms, such as the D, GS, and HS series. This lens is engineered to meet the exacting demands of large-venue installations, including rental and staging, large auditoriums, and simulation environments where optical precision and mechanical reliability are non-negotiable. It offers a versatile 1.2-1.5:1 throw ratio range, providing installers with the flexibility to achieve a desired image size from a relatively short throw distance, making it suitable for venues where the projector cannot be positioned far from the screen. The optical design utilizes high-index, low-dispersion glass elements with multi-layer anti-reflective coatings to maximize light transmission, minimize chromatic aberration, and ensure a sharp, high-contrast image across the entire projected field, even at the edges.

Constructed with a robust all-metal housing, the lens is built to withstand the rigors of professional use, including repeated installation and adjustment cycles. It features a manual zoom and focus mechanism with precise, smooth-action rings that allow for fine-tuning of image size and clarity. The lens incorporates an electronic interface that communicates directly with the connected Christie projector, enabling automated lens memory functions and the recall of specific zoom, focus, and shift settings when used with compatible models. This is particularly valuable in multi-configuration venues or rental applications where quick setup and tear-down are essential. The optical path is sealed to resist dust infiltration, helping to maintain performance clarity over the long term without the need for frequent internal cleaning.

This lens is a critical component for achieving specific installation geometries, enabling the projection of large, bright, and detailed images in spaces with fixed projector locations. Its performance is characterized by consistent edge-to-edge sharpness and minimal light fall-off, ensuring uniform brightness and color fidelity across the entire screen. As a dedicated accessory from a major manufacturer, it guarantees precise mechanical mounting and optimal electronic integration, providing system designers and integrators with a reliable, high-performance optical solution to complete their professional projection system.
