The Christie 118-100117-0 is a high-precision, dual-mode projection lens engineered for high-brightness, large-venue projectors compatible with 0.95-inch imaging panels. This lens provides two distinct optical paths calibrated for different native resolutions, allowing a single projector to be optimized for either SXGA+ (1400x1050) or full HD (1920x1080) output without swapping hardware. The primary mode offers a 1.2:1 throw ratio for SXGA+ content, while a simple internal adjustment switches the optical formula to a 1.1:1 throw ratio specifically for HD, ensuring minimal geometric distortion and maximum sharpness for each resolution. This dual functionality makes it a versatile and cost-effective solution for rental houses and fixed installations that utilize the same projector for different content standards, from detailed data visualization to high-definition video.

Constructed with high-index, low-dispersion glass elements, the lens is designed to handle the intense light output of high-lumen professional projectors while maintaining contrast and color fidelity across the entire image field. The optical assembly is housed in a rigid, lens-barrel-style chassis with precision mechanical mounts for secure, repeatable alignment within the projector's lens port. The fixed focal length design in each mode ensures consistent performance and eliminates the potential for drift or misalignment associated with zoom mechanisms, which is critical for permanent installations in control rooms, simulators, and large auditoriums where absolute image stability is required.

Installation and selection of the desired mode are performed by trained technicians, as the lens requires proper seating and calibration within the projector. Its design is focused on delivering maximum optical throughput with minimal light loss, a key factor when projecting over long distances or onto very large screens. The Christie 118-100117-0 represents a specialized optical component for system integrators who demand the highest image integrity and operational flexibility from their high-end projection systems, ensuring that both high-resolution data and video content are displayed with optimal clarity and geometric accuracy.
