About the Christie 104-114101-XX 2.8-4.5:1 0.95" SXGA+ / 2.6-4.1:1 CT 0.95" HD Projector Lens
The Christie 104-114101-XX is a high-precision, medium-throw zoom lens engineered for high-brightness professional projectors operating at SXGA+ and HD resolutions. This lens is designed to be part of Christie's comprehensive optical lineup for their 3-chip DLP and other high-end projection systems, commonly used in demanding applications such as large venue events, simulation environments, and premium cinema installations where precise image sizing and placement are critical. The specified 0.95-inch aperture indicates a large lens diameter, which is essential for gathering and projecting the immense light output from high-lumen xenon or laser light sources without vignetting or light loss, ensuring brightness uniformity across the entire screen.
The lens offers a versatile zoom range, specified as 2.8-4.5:1 for SXGA+ format projectors and 2.6-4.1:1 for HD format, providing system integrators with significant flexibility in projector placement. This range allows the same projector model to be installed in a variety of room geometries, as the image size can be finely adjusted via the zoom mechanism to fit the screen perfectly from a fixed throw distance. The optical construction utilizes multiple, high-quality glass elements with specialized anti-reflective coatings to maximize light transmission, ensure sharp corner-to-corner focus, and maintain accurate color fidelity. The robust, all-metal barrel protects these delicate internal components and maintains precise optical alignment over time, even in environments subject to vibration or thermal cycling.
As a critical component in the imaging chain, this lens attaches to compatible Christie projectors via a secure, proprietary mounting system. It features manual zoom and focus controls, allowing installers to make precise adjustments during setup to achieve a perfectly sharp and sized image. The combination of a large aperture, a useful zoom range, and Christie's optical expertise makes the 104-114101-XX lens a key enabler for achieving brilliant, high-contrast, and geometrically accurate visuals on large screens, fulfilling the stringent requirements of professional visual displays where image quality cannot be compromised.
