The Christie 118-100112-03 is a specialized, high-aperture ultra short-throw zoom lens engineered for premium digital cinema and large-venue projectors. Designed for Christie's high-brightness 3-chip DLP systems, this lens features a substantial 0.95-inch aperture to efficiently capture and project the immense luminous flux from high-output xenon or laser light sources. The lens provides two distinct zoom ranges: 1.5-2.0:1 for SXGA+ format projectors and 1.4-1.8:1 for HD format, offering a critical, albeit focused, degree of adjustment for fine-tuning image size. This capability is essential for installations where the projector must be positioned extremely close to the screen, such as in space-constrained projection booths, domed simulators, or architectural installations with severe throw distance limitations.

Optical performance is paramount in this lens, achieved through precision-ground multi-element glass groups with advanced anti-reflective coatings. These coatings maximize light transmission, ensure uniform illumination, and maintain exceptional color fidelity and contrast across the entire image area. The robust, all-metal barrel provides mechanical stability and protects the sensitive internal optics from environmental factors, ensuring long-term alignment and reliability. Manual zoom and focus rings allow installers to make meticulous adjustments during calibration, achieving a sharp, pixel-accurate image that meets the exacting standards of professional visual displays.

As a component of Christie's lens ecosystem, the 118-100112-03 attaches to compatible projector models via a secure, proprietary mount. Its ultra short-throw design not only solves significant spatial challenges but also enhances system efficiency by minimizing light loss over distance. This allows for the use of high-gain screens or reduces the required projector brightness for a given screen size. By delivering superior optical performance in the most demanding short-throw scenarios, this lens enables the deployment of Christie's top-tier projection technology in venues where traditional lenses are impractical, ensuring audiences experience brilliant, detailed, and immersive large-format visuals.
