The Barco R9832470 RLD W 0.77:1 is an ultra-wide-angle, short-throw fixed focal length lens designed for Barco's high-brightness installation projectors. With an exceptionally low throw ratio of 0.77:1, this lens allows the projector to be positioned extremely close to the screen while still producing a very large image. For example, to project a 100-inch wide image, the projector would need to be placed only about 77 inches (just over 6 feet) from the screen. This makes it an ideal solution for environments with severe space constraints, such as small meeting rooms, interactive displays, retail windows, or any installation where the projector must be mounted almost flush with the screen or in a very tight ceiling void.

Optical engineering is critical for a lens with such a wide field of view. The RLD W 0.77:1 utilizes advanced, precision-ground glass elements with specialized coatings to control distortion, chromatic aberration, and maintain edge-to-edge sharpness and brightness uniformity. Despite the challenging optical design, the lens is built to deliver the full light output and resolution of the compatible Barco projector, ensuring that image quality is not compromised. As a fixed focal length lens, it has no zoom capability; the image is focused during installation by precisely adjusting the lens position relative to the projector's imaging chip, a task typically performed by a certified technician using specialized tools.

The lens integrates with specific Barco projector models via a secure bayonet or locking mount, ensuring a rigid and vibration-free connection. It is part of Barco's comprehensive RLD lens family, providing system designers with a precise optical tool for unique architectural challenges. By enabling large-scale projection from an incredibly short distance, the Barco RLD W 0.77:1 lens opens up new possibilities for immersive visual experiences in spaces where traditional projection was previously impossible.
