Barco Projector lens. G-lens (0.75-0.95) - R9801840

Product Overview

The Barco R9801840 is a G-series short throw zoom lens with a 0.75-0.95:1 throw ratio at WUXGA, supplied with a lens ring. It is the widest, shortest-throw optic in the G-series lens line and replaces the earlier R9832781. The short throw allows a large image from a projector mounted very close to the screen. Its aperture range is f/2.3 to f/2.53.

Product Description

This lens is built for tight rooms and short-projection geometries where the projector sits just in front of the screen, such as small classrooms, simulation rooms, and confined ceiling mounts. The lens ships with its lens ring for mounting on G-series projectors. As shown in the product image, it uses the G-series bayonet mount for tool-free swaps. It is part of the same family as the longer-throw G 0.95-1.22:1 lens and the G 1.52-2.92:1 long zoom. Browse the full Barco projector and lens collection to match the right optic to your install.
