Barco R9832753 Zoom Standard Throw Lens for PGWU-62L PGWX-61B PGWX-62L PGXG-61B

Genuine Barco R9832753 Zoom Lens is an OEM optical accessory for Barco professional projectors, featuring a standard throw (Standard Throw) with a 1.26-1.58:1 throw ratio. Barco's official compatibility list covers 4 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 rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focus travel all meet the design specifications, eliminating the need to use keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not shown in the specifications table, please verify them with us based on the projector model. Ordering solely because two models appear similar risks purchasing a lens that will not fit.

2. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This genuine zoom lens has a throw ratio of 1.26-1.58:1, so the same image size corresponds to a range of installation distances. The lens can focus anywhere within that range.

The distances above are the clear measurements from the front surface of the lens to the screen and do not include cooling clearance or cabling space at the rear of the projector. They are calculated for a 16:10 image; actual distances should be confirmed through on-site measurements and the manufacturer's manual.

Image quality differs between the two ends of the zoom range: the image is brighter and the edges are slightly softer near the short-throw end, while the edges are sharper and brightness decreases slightly near the long-throw end. Where venue conditions allow, the middle of the range is recommended. After installation, first find the sharpest position using the focus ring, then fine-tune the lens shift.

3. Compatible Models (4 Models)

The table below is taken from the official compatibility list. Brightness and resolution are populated from the projector model database; unavailable values are marked “—” and are not estimated.

To confirm compatibility with a model not listed, send us a photo of the projector nameplate and the existing lens. Platforms of the same generation often share the same mount, but the risk of ordering based solely on a similar model is not worth taking.

Throw Ratios by Projector Series

Although the same R9832753 Zoom lens is used across the series listed below, the nominal throw ratio varies by series. Use the value corresponding to the actual projector series when selecting a lens.

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. Genuine lenses are designed for specific panel sizes. If the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or edge light loss.
• Calculate the installation distance first. This lens has a rated throw ratio of 1.26-1.58:1. Use the table in Section 2 to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, and even a zoom lens should be allowed 10–20 cm of clearance at both ends of the range.
• Verify the mount and locking mechanism. Genuine lenses are calibrated to the mount of the corresponding projector series. You must hear the locking mechanism click into place after installation. A skewed image or soft edges usually indicate that the lens is not fully locked, rather than a problem with the lens itself.

If you are unsure, send us one photo each of the projector nameplate and the lens nameplate. Verification against the actual items is the safest approach.
