The Barco R9832742 RLD lens with a 1.45–1.74:1 throw ratio is a professional zoom projection lens designed specifically for use with compatible Barco digital projectors, notably the RLM-W6 and RLM-W8 series of three-chip DLP projectors. This zoom lens allows system integrators and AV professionals to adjust the projection image size without moving the projector itself, making it ideal for versatile installation environments such as corporate auditoriums, large meeting spaces, houses of worship, exhibition halls, and rental/staging applications. Because Barco’s projector platforms are widely used in demanding large-venue installations, this lens provides the flexibility needed to optimize image placement and screen coverage from a range of installation distances while maintaining clear, high-quality projection.

Barco’s RLD lenses are engineered with precise optical elements that maintain image uniformity and brightness despite zoom adjustments. The 1.45–1.74:1 throw ratio places this lens in the moderate-zoom category, making it suitable for installations where projectors are mounted at a moderate distance from the projection surface. While Barco does not publish exhaustive optical charts publicly for this lens, its compatibility with high-end three-chip DLP systems means it supports professional video, data, and multimedia projection requirements with robust build quality. The lens is designed to maintain mechanical and optical integrity over long periods of professional use, ensuring reliable performance in critical AV environments.
