The Christie 118-100115-XX is a premium, large-aperture zoom lens from the Integrated Lens System (ILS) family, designed for high-brightness 3-chip DLP projectors used in large-venue, cinematic, and simulation applications. This lens features a versatile zoom ratio, offering a range suitable for installations where throw distance or screen size may require flexibility. The "0.95-inch" designation refers to the large, fast aperture (f/1.0 - f/1.2 typical), which allows for maximum light transmission from the projector, making it ideal for achieving extremely high brightness levels on massive screens, such as those in large auditoriums, domes, or premium large-format cinema complexes. The lens is optically engineered to maintain edge-to-edge sharpness, high contrast, and minimal distortion across its entire zoom and focus range.

Constructed with precision glass elements and robust mechanical components, this lens is built for reliability in permanent installations. It supports both SX+ and HD resolution formats, ensuring compatibility with a range of high-end Christie projector models. The ILS design includes features like electronic communication with the projector for storing lens calibration data, motorized zoom, focus, and shift functions, which can be controlled remotely for precise alignment and easy adjustment during installation and maintenance. The lens barrel is typically sealed to resist dust, a critical feature for maintaining image quality over thousands of hours of operation.

This lens is a critical component for system integrators and projection designers working on the most demanding visual projects. Its combination of a fast aperture, high optical quality, and motorized controls enables the creation of stunning, bright, and detailed images on very large surfaces. It is the choice for applications where absolute image fidelity, brightness, and installation precision are non-negotiable, such as in flagship cinemas, planetariums, and high-end command and control centers.
