The Barco RLD series lens with a 2.25-3.0:1 zoom ratio is a high-performance optical component designed for specific Barco installation and large-venue projectors. This lens offers a versatile medium zoom range, providing installers with significant flexibility in positioning the projector relative to the screen. With this zoom ratio, the projector can be placed at a distance where the image size is between 2.25 and 3.0 times the screen width, allowing for fine-tuning of the image size during installation without physically moving the projector. This adaptability is crucial in fixed installations where the exact throw distance may be constrained by room architecture, ceiling height, or existing infrastructure, ensuring the projected image can be perfectly fitted to the screen.

Constructed with precision-ground glass elements and multi-layer coatings, this lens is engineered to transmit the high light output of Barco's professional projectors with minimal loss, maintaining brightness, contrast, and color fidelity across the entire zoom range. The lens assembly is built to maintain precise optical alignment and focus stability, even under the thermal stresses of extended operation. Manual zoom and focus rings allow for smooth, calibrated adjustments during setup. Once configured, the lens maintains its settings reliably, contributing to the long-term stability of the installation. The robust housing protects the internal optics from dust and physical shock.

This lens integrates seamlessly with compatible Barco projector models via a secure bayonet or locking mount, ensuring a vibration-free connection. It is part of Barco's comprehensive ecosystem of interchangeable lenses, allowing system designers to select the exact optical characteristics required for a venue's specific geometry and screen size. By offering a balanced zoom range, this RLD lens provides a practical solution for many professional applications, from corporate boardrooms and lecture halls to control rooms and houses of worship, where installation flexibility and consistent image quality are paramount.
