Barco R9832764 Zoom Long-Throw Lens for PHWU-81B PHWX-81B PHXG-91B

Barco OEM Lens R9832764 Zoom is an original optical accessory for Barco engineering projectors. It is a long-throw lens with a throw ratio of 1.68-2.37:1. The official compatibility list covers 3 models; before installation, simply verify the projector model and panel size—no adapter rings are needed. The value of an OEM lens lies not in a few extra specifications, but in its factory calibration to the optical path and mount of that projector series. Its image circle, edge illumination, and focus travel are all designed values, so there is no need to use keystone correction to compensate for image quality.

I. Lens Specifications

Brand	Barco (Barco)
Lens Model	R9832764 Zoom
Throw Ratio	1.68-2.37:1
Product Type	Long Throw
Compatible Models	3 models
Warranty	12 months; for damage not caused by the user, after-sales service is available, subject to the date on the shipping documentation

The above specifications are subject to the official manufacturer specifications. For mechanical dimensions, flange distance, and mount type not shown in the specifications table, please contact us with the projector model for verification. Ordering directly based on a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (1.68-2.37:1), so a given image size corresponds to a range of installation distances, and the lens can focus at any distance within that range.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 3.61 – 5.10 m
120 inches	2.58 m	Approx. 4.33 – 6.11 m
150 inches	3.22 m	Approx. 5.42 – 7.64 m
200 inches	4.30 m	Approx. 7.22 – 10.19 m

These distances represent the clear distance from the front face of the lens to the screen and do not include space behind the projector for ventilation and cable connections. The figures are based on a 16:10 image; in practice, rely on on-site measurements and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the close end, the image is brighter and the edges are slightly softer; toward the far end, the edges are sharper and the image is slightly dimmer. When the venue allows, use the middle of the range. After installation, first find the sharpest setting on the focus ring, then fine-tune the lens shift.

III. Compatible Models (3 Models)

The following table is based on the official compatibility list. Brightness and resolution are filled in from the model database; where the data is unavailable, “—” is shown, and no values are estimated.

Model	Brightness	Resolution
PHWU-81B	7500 lumens	1920x1200
PHWX-81B	7300 lumens	1280x800
PHXG-91B	8500 lumens	1024x768

To check whether a model not on the list is compatible, send us photos of the projector nameplate and the existing lens. Platforms from the same generation often share the same mount, but the risk of ordering based on a similar model is not worth taking.

Throw Ratio by Projector Model Series

When the same R9832764 Zoom is used with the series listed below, the nominal throw ratio varies. Select the value based on the series of the actual projector.

Model Series	Throw Ratio
—	1.68-2.37:1

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution. Each OEM lens is designed for a specific panel size. If the panel specification differs, the image circle cannot cover the full panel, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.68-2.37:1. Use the table in Section II to calculate the distance for your venue dimensions. A fixed-focal-length lens offers no adjustment range, while a zoom lens should also allow an additional 10–20 cm at both ends.
• Verify the mount and locking mechanism. Each OEM lens is calibrated to the mount of its projector series. After installation, you must hear the lens lock into place. 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 photo of the existing lens nameplate, then send them to us. Verification against the actual hardware is the safest approach.
