About the Christie 104-130101-XX Zoom Projector Lens, 7.5-11.2:1 0.95" SXGA+ / 6.9-10.4:1 0.95" HD
The Christie 104-130101-XX is an ultra-high-ratio zoom lens engineered for maximum projector placement flexibility in demanding, large-scale fixed installations. With an extraordinary zoom range of 7.5-11.2:1 for SXGA+ projectors (and 6.9-10.4:1 for HD models), this lens provides one of the widest adjustment capabilities available, allowing the image size to be varied dramatically without physically moving the projector. This is critical for complex venues like planetariums, simulation facilities, large auditoriums with multiple screen options, or installations where the projector must be housed in a fixed, remote location. Such extreme flexibility allows system integrators to use a single lens model across different room geometries or to fine-tune the image with precision after the projector is permanently mounted.
This lens is designed for high-brightness projectors utilizing 0.95-inch DLP technology, ensuring full compatibility with the light engine and native resolution of compatible SXGA+ and HD models. Its complex optical path, necessitated by the vast zoom range, incorporates multiple precision glass elements to maintain image sharpness and minimize distortion across the entire zoom and focus spectrum. The trade-off for this immense flexibility is typically a relatively small maximum aperture, which reduces total light output compared to lenses with a smaller zoom ratio—a calculated compromise for gaining unparalleled placement options. Built into a substantial metal barrel, the lens includes manual zoom and focus controls for precise calibration during the installation process.
For architects, consultants, and AV integrators designing sophisticated visualization environments, the Christie 104-130101-XX is a specialized tool that solves complex throw-distance challenges. It enables the creation of large, seamless images from projector positions that would be impossible with standard lenses, making it an essential component for customized, high-end projection systems where the projector's location is severely constrained by the architectural design or functional requirements of the space.
