The Christie 144-107109-01 is a professional-grade, motorized zoom lens designed as a genuine accessory for specific high-brightness Christie projectors, particularly within the Roadster, Boxer, and M Series families. This lens offers a versatile zoom range of 2.71:1 to 3.89:1, categorizing it as a medium-to-long throw lens suitable for installations where the projector must be positioned a considerable distance from the screen while still allowing for some post-installation adjustment to perfectly fit the image. Its optical formula is engineered with precision-ground glass elements and multi-layer coatings to maximize light transmission, ensure edge-to-edge sharpness, and maintain the high contrast and color fidelity of the host projector's image. The lens is built to seamlessly integrate with the projector's optical engine and electronic control system, preserving the integrity of the projected light path from the DMD chip to the screen.

A key feature of this lens is its full motorization, allowing for remote control of zoom, focus, and lens shift functions directly from the projector's menu, a compatible remote, or network control software like Christie's LiteSite. This capability is crucial in permanent installations, such as large auditoriums, houses of worship, or command and control centers, where the projector may be mounted in a difficult-to-access location like a high ceiling or an enclosed projection booth. The motorized adjustments enable fine-tuning of the image during initial calibration and allow for future adjustments if the screen or setup changes, all without the need for a technician to physically handle the lens. The lens maintains precise calibration and focus stability once set, ensuring a consistently sharp image over thousands of hours of operation.

Constructed with a durable metal barrel and housing, the lens is built to withstand the thermal environment of a high-output projector and to maintain its optical alignment over time. As a genuine Christie component, it is designed to communicate flawlessly with the projector, enabling features like automatic lens recognition and configuration. This specific zoom range provides installers with meaningful flexibility, allowing them to compensate for mounting positions that are not at the ideal "standard" throw distance. By offering a balance of reach and adjustability, the Christie 144-107109-01 zoom lens is an essential tool for system integrators who need to achieve a perfectly sized and positioned image in challenging large-venue projection applications.
