The Christie 38-809072-XX is a professional high-brightness zoom lens designed for large-venue and cinema-grade projectors requiring a versatile throw ratio to accommodate various room sizes and screen configurations. This lens falls within a category of optics engineered to handle the intense light output of high-lumen xenon or laser-lit projection systems, typically those found in commercial cinemas, large auditoriums, and specialized visualization facilities. The 4.3:1 to 6.0:1 zoom ratio provides a broad range of adjustment, allowing installers to precisely match the projected image to the screen from a variety of throw distances without moving the projector itself. This flexibility is crucial for tailoring a standard projector model to the specific architectural constraints of an installation site.

Constructed with precision optics, the lens utilizes multiple element groups with specialized anti-reflective coatings to maximize light transmission and ensure consistent color fidelity across the entire image area. The high-brightness designation indicates that the lens is specifically designed to handle the thermal and luminous flux of high-output light sources without introducing hotspots, color fringing, or significant light loss. The robust, all-metal barrel protects the delicate internal glass elements from dust, vibration, and misalignment, ensuring long-term optical stability in demanding 24/7 operational environments. Manual zoom and focus rings provide smooth, precise adjustment during installation calibration.

As a component of a high-end projection system, this lens attaches to compatible Christie projector models via a standardized lens mount, likely part of Christie's proprietary Integrated Lens System (ILS) or a similar secure interface. Its performance is integral to the final image quality, affecting sharpness, brightness uniformity, and geometric accuracy. By offering a substantial zoom range within a high-brightness platform, the Christie 38-809072-XX lens provides system designers and integrators with a critical tool for optimizing screen size and image quality from a fixed projector location, enabling a single projector model to serve a wider array of venue layouts while maintaining cinematic image standards.
