This high-brightness projection lens offers a 3.0-4.3:1 throw ratio range for professional video projection applications. Specifically engineered for the Christie Roadie HD+35K projector series (model 113-003104-XX), it delivers optimal image quality across varying installation distances. The lens enables precise image placement where projection distance significantly exceeds screen width, characteristic of long-throw configurations. Designed for demanding venue environments requiring high brightness performance, this optical solution was part of Christie's professional projection ecosystem before reaching end-of-support status. Its technical specifications support accurate throw distance calculations using Christie's official lens calculator tools.
