The Christie 118-100117-01 is a high-precision, fixed focal length projection lens engineered for Christie's 3-chip DLP projector platforms, specifically those utilizing 0.95-inch DarkChip DMD technology. Designed as part of Christie's Integrated Lens System (ILS), this 1.2:1 throw ratio lens is optimized for installation scenarios where the projector's position relative to the screen is fixed and known. Its optical formula is crafted to deliver exceptional sharpness, high contrast, and minimal chromatic aberration across the entire image, meeting the rigorous demands of professional applications such as command and control centers, simulation environments, large-venue staging, and digital cinema. The lens maintains consistent performance with the native resolutions of SX+ (1400x1050) and HD (1920x1080) projectors, ensuring pixel-accurate image reproduction without softness or distortion at the edges.

The lens incorporates advanced coatings and multi-element glass construction to maximize light throughput and color fidelity, which is critical for 3-chip DLP systems that rely on precise color convergence. Its robust, all-metal housing is built for durability in permanent installations and includes integrated mounting hardware for secure attachment to compatible Christie projector models. As a fixed lens, it does not offer zoom or lens shift functionality, which necessitates precise pre-calculation of throw distance and positioning during the system design phase. This simplicity often translates to superior optical performance and reliability compared to more complex motorized lenses, as there are fewer moving parts that could drift or require calibration over time.

Integration into a Christie projection system is streamlined through the ILS design, which ensures mechanical and optical compatibility, allowing for quick and secure lens changes if needed. The lens plays a fundamental role in determining the projection footprint; with a 1.2:1 throw ratio, it projects a large image from a relatively short distance, making it suitable for rooms with limited depth. By providing a dedicated, high-quality optical solution for fixed installation 3-chip DLP projectors, this lens is a critical component in building a stable, high-performance visual display system where image integrity, brightness uniformity, and long-term reliability are non-negotiable.
