About the Christie ILS 1.25-1.6:1 SX+ / 1.16-1.49:1 HD Zoom Lens
The Christie ILS 1.25-1.6:1 is an ultra short-throw zoom lens designed specifically for high-brightness digital cinema and large venue projectors within Christie's Integrated Lens System. This optical component is engineered for installations where spatial constraints are severe, enabling a projector to be positioned exceptionally close to the screen while still producing a large, bright image. The specified zoom ratios—1.25-1.6:1 for SX+ format and 1.16-1.49:1 for HD format—provide a critical, albeit limited, range of adjustment. This allows system integrators to fine-tune the image size with precision, ensuring perfect screen coverage from a fixed location that would be impossible with a standard or long-throw lens, making it indispensable for retrofits, small booths, domed simulations, and unique architectural settings.
Constructed to handle the intense output of xenon or laser light sources, the lens incorporates large-diameter, precision-ground glass elements with advanced multi-layer coatings. These coatings are vital for maximizing light transmission, maintaining color accuracy, and ensuring uniform brightness across the entire field of view without vignetting. The robust, all-metal barrel provides durable protection for the sensitive internal optics, safeguarding against dust, vibration, and thermal fluctuations to guarantee long-term alignment and performance stability. Smooth manual zoom and focus rings offer installers the tactile control needed for meticulous calibration, achieving a sharp, geometrically accurate image that meets the high standards of professional visual displays.
As a dedicated component of Christie's lens ecosystem, it attaches securely to compatible projector models via a proprietary ILS mount, ensuring a rigid and reliable interface. The ultra short-throw characteristic of this lens not only solves spatial challenges but can also improve system efficiency by reducing the required luminous output for a given screen size due to minimal throw-related light loss. By delivering exceptional optical performance in the most demanding space-limited scenarios, the Christie ILS 1.25-1.6:1 lens empowers the deployment of premium projection technology where traditional lenses cannot operate, ensuring audiences experience vibrant, detailed, and immersive visuals from remarkably short projection distances.
