The Christie 104-137101-01 is a high-performance, short zoom lens designed for high-brightness, high-resolution projectors used in installations where space is at a premium and a large image is required from a relatively short throw distance. Its optical design is optimized for projectors with 0.95-inch DLP imagers, providing two distinct zoom ranges: a 1.16-1.49:1 range for HD (1920x1080) resolution and a 1.26-1.61:1 range for SXGA+ (1400x1050) resolution. This relatively narrow zoom capability allows for fine-tuning of the image size and precise alignment, which is critical in fixed installations such as command and control centers, simulation environments, large boardrooms, and entertainment venues where the projector position is fixed but the exact screen size or placement may need slight adjustment.

Constructed with precision glass elements and housed in a robust metal barrel, the lens is built for durability in demanding 24/7 operational environments. It features a large maximum aperture to ensure maximum light transmission from the projector's light engine, preserving brightness even with the increased light path of a zoom lens. The inclusion of manual zoom and focus controls allows installers to achieve a perfectly sized and sharp image during setup. By offering a short zoom range with high light throughput and compatibility with specific high-resolution projectors, this lens enables integrators to deploy projectors in tight spaces while still achieving large, bright, and detailed imagery, making it a key component for specialized professional installations.
