About the Christie 38-809051-51 Zoom Projector Lens, 1.8-2.4:1
The Christie 38-809051-51 is a professional short-throw zoom lens engineered for Christie's high-performance digital cinema and large-venue projectors. With a compact zoom range of 1.8:1 to 2.4:1, this lens is specifically designed for installations where the projector must be placed relatively close to the screen, a common requirement in space-constrained projection booths, retrofitted cinema spaces, or specialized applications like simulation domes and control rooms. Its optical formula is meticulously calculated to deliver a large, bright image from a short distance, minimizing the overall footprint of the projection system while maintaining the high image quality demanded by professional environments. This makes it an essential component for integrators working within strict architectural limitations.
The lens is built with high-precision glass elements and advanced multi-layer coatings that are optimized for the specific spectral output of high-intensity xenon or laser light sources. These coatings maximize light throughput, enhance contrast, and ensure uniform illumination across the entire field of view, preventing vignetting or color shifts at the corners of the image. The robust, all-metal housing safeguards the internal optics from environmental factors and mechanical stress, ensuring consistent alignment and performance over thousands of hours of operation. Smooth manual zoom and focus rings allow technicians to make precise adjustments during installation, achieving a perfectly focused and sized image on the screen.
As part of Christie's lens ecosystem, the 38-809051-51 model attaches to compatible projectors via a secure, proprietary mount, ensuring a rigid and reliable interface. Its short-throw capability not only saves valuable space but can also reduce the required brightness needed from the projector for a given screen size, as light loss over distance is minimized. By providing exceptional optical performance in a short-throw configuration, this lens enables the deployment of Christie's powerful projection technology in a broader range of venues, ensuring that even installations with challenging spatial constraints can benefit from crisp, vibrant, and immersive large-format visuals.
