The Christie 113-104106-02 Roadie High-Brightness Projector Lens is a highly specialized, fixed short-throw lens designed to work with Christie's professional-grade Roadie 2K and 4K series DLP projectors. Engineered for high-brightness applications, this lens provides a precise and consistent throw ratio, making it an ideal solution for scenarios where the projector needs to be placed relatively close to a large screen or surface, such as in large venue events, staging, or auditoriums. Its optical design ensures that even with a short throw distance, the projected image maintains exceptional clarity, focus, and brightness, fully leveraging the capabilities of the associated high-lumen projectors.

Constructed for demanding professional environments, the lens is built with durable materials designed to withstand the rigors of frequent transport and setup typical of rental and staging markets. The "High Brightness" designation indicates its optimized optical path that minimizes light loss, allowing the projector to deliver maximum possible lumen output to the screen. The fixed throw ratio design, unlike a zoom lens, is often preferred in specific installation scenarios for its consistent performance and simplified setup once the correct throw distance is established.

This particular lens is compatible with a range of high-end, large-format projectors, including models from the Christie Roadie 25K, Roadie HD+30K, Roadie HD+35K, and D4K series. It provides system flexibility for professional AV technicians and integrators, enabling them to achieve a 100-inch diagonal image from a distance of approximately 5 feet 4 inches, depending on the specific projector model used. The lens is part of an ecosystem of accessories that allows professional users to tailor their projection systems to meet very specific venue requirements.
