Barco R9832762 Zoom Telephoto Projector Lens: RLS-W12 Compatibility

Barco Genuine Lens R9832762 Zoom is a genuine optical accessory for Barco professional projectors. It is a long-throw lens (Long Throw) with a throw ratio of 2.40-4.00:1. Barco's factory compatibility list covers 1 model. Before installation, simply verify the projector model and panel size; there is no need to improvise with an adapter ring. The value of a genuine lens lies not in the extra rows of figures in a specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all match their design values, eliminating the need to compensate for image quality with keystone correction.

1. Lens Specifications

The above specifications are subject to the manufacturer's original specifications. For mechanical dimensions, flange distance, and mount type not shown in the table, please contact us with the projector model so we can verify them. Ordering solely because a model number is similar may result in a lens that does not fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This genuine lens is a zoom lens (2.40-4.00:1), so a given image size corresponds to a range of installation distances. It can focus anywhere within that range.

These figures represent the clear distance from the front surface of the lens to the screen and do not account for ventilation or cabling space behind the projector. They are calculated for a 16:10 aspect ratio; for the actual installation, on-site measurements and the manufacturer's manual take precedence.

Image quality differs at the two ends of the zoom range: at the short-throw end, the image is brighter and the edges are slightly softer; at the long-throw end, the edges are sharper and brightness is slightly lower. Where space permits, positioning in the middle of the range is recommended. After installation, find the sharpest image position using the focus ring, then fine-tune the lens shift.

3. Compatible Models (1 model)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution are populated from the model database; values that cannot be obtained are shown as —, and no assumptions are made.

For models not on the list, please send us photos of the projector nameplate and the existing lens for verification. Platforms of the same generation often share the same mount, but ordering based solely on a similar model number carries unnecessary risk.

Throw Ratios by Model Series

The nominal throw ratio varies by model series when the same R9832762 Zoom lens is installed. Select the value based on the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. The genuine lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. The nominal throw ratio of this lens is 2.40-4.00:1. Use the table in Section 2 to determine the distance for your installation site. A fixed-focus lens offers no margin, and even a zoom lens should leave 10–20 cm of adjustment room at both ends of the range.
• Check the mount and locking mechanism. The genuine lens is calibrated to the mount of that projector series, and you must hear it lock into place after installation. A skewed image or soft edges are usually caused by incomplete locking, not by the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate, and send them to us. Checking the actual hardware is the safest approach.
