The Christie 113-100113-01 is a high-performance, short-throw zoom lens engineered specifically for Christie's high-brightness 3-chip DLP projectors used in demanding cinema and large venue applications. This lens model, part of Christie's Integrated Lens System (ILS), is designed to provide exceptional optical clarity and light transmission for projectors operating at SX+ and HD native resolutions. Its versatile zoom range, designated as 2.0-2.8:1 for SX+ format and 1.8-2.6:1 for HD format, offers installers significant flexibility in projector placement, allowing for shorter throw distances in space-constrained booths or rooms while still achieving a large screen image. This makes it particularly valuable for cinema retrofits, premium large-format auditoriums, and simulation environments where precise screen coverage from a limited distance is critical.

The lens is constructed with precision-ground glass elements and multi-layer coatings optimized for the spectral output of high-intensity xenon or laser light sources used in professional cinema projectors. This optical design maximizes brightness uniformity and minimizes aberrations, ensuring sharp corner-to-corner focus and accurate color fidelity across the entire zoom range. As part of the ILS series, it features a robust, all-metal housing and a standardized, secure mounting mechanism designed for quick and reliable installation onto compatible Christie projector models. The lens includes manual zoom and focus controls, allowing for fine-tuning during setup to achieve a perfectly sharp and sized image on the screen.

This lens is a key component in building a high-quality projection system, directly impacting the final image's sharpness, brightness, and geometric accuracy. Its short-throw capability can simplify architectural challenges by allowing the projector to be located closer to the screen, potentially reducing the required depth of the projection booth. The Christie ILS lens series, including this model, is recognized for its durable construction and optical excellence, providing system integrators and cinema technicians with a reliable tool to ensure that the projector's native performance is fully realized on the screen for a immersive viewing experience.
