Barco R9832754 Zoom Standard-Throw Lens for PGWU-61B PGWU-62L PGWU-62L-K PGWX-62L PGXG-61B

Barco Genuine Lens R9832754 Zoom is a genuine optical accessory for Barco engineering projectors, designed for standard throw (Standard Throw), with a throw ratio of 1.22-1.53:1. The manufacturer's compatibility list covers 5 models; before installation, simply verify the projector model and panel size—there is no need to make do with adapter rings. The value of a genuine lens lies not in the extra figures in the specification table, but in the fact that it is factory-calibrated to the optical path and lens mount of that projector series: once installed, the image circle, edge illumination, and focus travel all meet their design values, with no need to use keystone correction to compensate for image quality.

I. Lens Specifications

The above specifications are subject to the manufacturer's specifications. For mechanical dimensions, flange distance, and lens mount type not shown in the specification table, please contact us with the projector model for verification. Ordering solely because the model numbers are similar carries the risk that the lens will not fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This genuine lens is a zoom lens (1.22-1.53:1), so a given image size corresponds to a range of distances; any position within that range can be brought into focus during installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space for rear housing ventilation and wiring. Based on a 16:10 image format, the actual values should be verified by on-site measurement and in accordance with the manufacturer's manual.

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

III. Compatible Models (5 Models)

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 have not been estimated.

To determine whether a model not on the list can be used, send us photos of the projector nameplate and the existing lens. Platforms of the same generation often share the same lens mount, but the risks of ordering based on similar model numbers are not worth taking.

Throw Ratios by Model Series

When the same R9832754 Zoom is installed on the series listed below, the nominal throw ratio differs. For selection, use the value for the series of the actual projector.

IV. Three Checks Before Replacement

• Confirm the projector panel and resolution. Genuine lenses are designed for specific panel sizes. 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. This lens has a nominal throw ratio of 1.22-1.53:1. Apply it to your venue dimensions using the table in Section 2. A fixed-focus lens provides no adjustment margin, while a zoom lens requires 10–20 cm of clearance at both ends.
• Verify the lens mount and locking mechanism. Genuine lenses are calibrated to the lens mount of that projector series. You must hear the lens click into the locked position after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate, then send them to us. Verification against the actual hardware is the most reliable approach.
