Barco R9832766 Zoom Standard Throw Lens for PHWU-81B PHWX-81B PHXG-91B

Barco Genuine Lens R9832766 Zoom is an original optical accessory for Barco professional projectors. It is a Standard Throw lens with a throw ratio of 0.80-1.00:1. The manufacturer's compatibility list covers 3 models. Before installation, simply verify the projector model and display panel size; adapter rings are not needed. The value of an original 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 lens mount of that model series. Once installed, the image circle, edge illumination, and focus travel are all as designed, eliminating the need to compensate for image quality with keystone correction.

I. Lens Specifications

Brand	Barco (Barco)
Lens Model	R9832766 Zoom
Throw Ratio	0.80-1.00:1
Product Type	Standard Throw lens
Compatible Models	3 units
Warranty	12 months; after-sales service is available for damage not caused by improper use, subject to the date on the shipping document

The above specifications are subject to the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type are not listed in the specifications table. Please provide your projector model so that we can verify them. Placing an order based solely on a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This original lens is a zoom lens (0.80-1.00:1). A given image size corresponds to a range of installation distances, and the lens can be focused at any distance within that range.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	approx. 1.72 – 2.15 m
120 inches	2.58 m	approx. 2.06 – 2.58 m
150 inches	3.22 m	approx. 2.58 – 3.22 m
200 inches	4.30 m	approx. 3.44 – 4.30 m

These figures represent the clear distances from the front surface of the lens to the screen and do not include rear projector cooling and wiring space. They are calculated for a 16:10 image; actual distances should be verified on site and in accordance with the manufacturer's manual.

Image quality varies 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 decreases slightly. Where the installation space 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 taken from the manufacturer's compatibility list. Brightness and resolution are populated from the projector model database; where data is unavailable, “—” is shown instead of making assumptions.

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

To check whether a model not listed here is compatible, please send us photographs of the projector nameplate and the existing lens for verification. Platforms from the same generation often share the same mount, but ordering based solely on a similar model introduces unnecessary fit risks.

Throw Ratios by Projector Model Series

The specified throw ratio varies by model series when the same R9832766 Zoom is installed. Select the value based on the series of the actual projector.

Model Series	Throw Ratio
—	0.80-1.00:1

IV. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution. Original lenses are designed for specific panel sizes. If the panel specifications differ, the image circle cannot cover the full image area, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. This lens has a specified throw ratio of 0.80-1.00:1. Use the table in Section II to calculate the distance based on the dimensions of your installation space. A fixed-focus lens provides no adjustment margin, and even a zoom lens requires a 10–20 cm margin at both ends of the range.
• Check the mount and locking mechanism. Original lenses are calibrated to the mount of the corresponding model series. After installation, you must hear the locking mechanism fully engage. A skewed image or soft edges are usually caused by incomplete locking, not by a problem with the lens itself.

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