About the Christie 144-103105-XX 1.13-1.31:1 Projector Zoom Lens
The Christie 144-103105-XX is a short-throw zoom lens designed for high-brightness, large-venue digital cinema and professional projection systems. With a versatile zoom ratio providing throw ratios from 1.13:1 to 1.31:1, this lens allows for flexible projector placement closer to the screen, making it ideal for environments with space constraints such as auditoriums, planetariums, and large command centers. The optical design is engineered to handle the intense light output of high-lumen 3-chip DLP projectors while maintaining exceptional edge-to-edge sharpness, contrast, and color uniformity across the entire image. This lens is a critical component for achieving precise image geometry and minimal distortion on large, flat or curved screens.
Constructed with precision-aligned glass elements housed in a robust metal barrel, the lens is built for thermal stability and long-term reliability in permanent installations. The zoom and focus mechanisms are designed for smooth, tool-assisted adjustment, allowing installers to fine-tune the image size and clarity during setup with repeatable accuracy. The lens mount is engineered for a secure, flange-focused connection to compatible Christie projectors, ensuring optimal optical alignment and maintaining focus integrity even under mechanical stress or thermal changes common in high-output projection environments.
This lens model supports high-resolution formats, including 2K and 4K DCI, making it suitable for both cinematic and high-resolution simulation applications. Its short-throw capability enables the creation of very large images from a relatively short distance, reducing projector room depth requirements and simplifying installation logistics. The Christie 144-103105-XX represents a specialized optical tool that balances placement flexibility with uncompromising image fidelity, meeting the exacting demands of large-scale, professional visual installations.
