The Christie 104-111101-01 is a fixed focal length (prime) lens engineered for high-brightness Christie Roadster series projectors with 0.95-inch 3-chip DLP technology. With a fixed throw ratio of 1.2:1 for SXGA+ models and 1.1:1 for HD models, this lens provides no zoom capability, meaning the image size is determined solely by the distance between the projector and the screen. This design prioritizes optical performance, typically offering a larger maximum aperture compared to zoom lenses, which results in higher light transmission and better preservation of the projector's native brightness. Fixed lenses like this are the preferred choice for installations where the projector's location relative to the screen is precisely known and unchanging, such as in permanent auditoriums, command and control centers, or digital cinemas, where maximizing light output and image sharpness is critical.

Constructed with precision glass elements in a robust metal housing, the lens is built for durability and reliable performance in demanding fixed installations. The absence of moving parts for zoom simplifies the optical path, often contributing to superior edge-to-edge sharpness and reduced geometric distortion. Installers must calculate the required throw distance with great accuracy during the design phase, as no adjustment for image size is possible after mounting. For integrators designing high-performance systems with compatible Christie Roadster projectors, the 104-111101-01 offers a solution that delivers optimal brightness and image fidelity for applications where the projection geometry is fixed and the highest possible light throughput is required.
