The Christie 121-119102-01 is a short throw zoom lens engineered for Christie projectors that require flexible placement in space-constrained installations. With a 1.1-1.7:1 zoom ratio, it provides a valuable degree of adjustment for fine-tuning image size while maintaining the characteristic of a short-throw lens. This allows the projector to be positioned closer to the screen than a standard lens would permit, yet still offers installers the ability to optimize the picture after mounting without physically moving the projector. This capability is particularly useful in environments like classrooms, meeting rooms, or retail displays where the throw distance is limited by room depth or architectural features, but exact screen alignment needs precision.

Designed to match the optical and illumination characteristics of its compatible Christie projector models, this lens ensures that image sharpness, brightness uniformity, and color fidelity are preserved across its entire zoom range. Its construction utilizes quality glass elements within a durable housing, built for reliable performance in permanent commercial installations. The short zoom range helps maintain good light transmission efficiency. For AV integrators, the Christie 121-119102-01 represents a practical tool that bridges the gap between fixed short-throw lenses and more flexible standard zooms, providing an optimal balance for installations where projector placement is restricted but some final adjustability is still necessary.
