Barco R9832781 Zoom Standard Throw Lens Overview: PGWU-61B PGWU-62L PGWX-61B PGWX-62L

Barco Original Lens R9832781 Zoom is an OEM optical accessory for Barco installation projectors, featuring a standard throw (Standard Throw) and a throw ratio of 0.75-0.95:1. The official compatibility list covers 4 models; before installation, simply verify the projector model and panel size, with no need for adapter rings. The value of an original lens lies not in a few extra specification figures, but in its factory calibration to the optical path and mount of the corresponding projector series: once installed, the image circle, edge illumination, and focus travel all operate at their designed values, with no need to compensate for image quality using keystone correction.

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 contact us with the projector model for verification. Ordering directly based on a similar model carries the risk of the lens not fitting.

2. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This original lens is a zoom lens (0.75-0.95:1), so a given image size corresponds to a range of installation distances. Any position within this range can be focused during installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space required for rear cooling and cabling. They are calculated for a 16:10 image; actual values should be verified through on-site measurement and in accordance with the manufacturer's manual.

Image performance differs at the two ends of the zoom range: the image is brighter and the edges slightly softer near the close end, while the edges are sharper and the brightness slightly lower near the wide end. Where venue conditions allow, the middle of the range is recommended. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift.

3. Compatible Models (4 Models)

The following list is taken from the manufacturer's official compatibility list. Brightness and resolution are populated from the model database; unavailable values are marked “—” and are not estimated.

To determine whether a model not on the list is compatible, send us photos of the projector nameplate and the existing lens for verification. Projectors based on the same-generation platform often share the same mount, but ordering based solely on a similar model is not worth the risk.

Throw Ratios by Projector Series

The nominal throw ratio varies among the following series when the same R9832781 Zoom lens is installed. Select the value according to the series of the actual projector.

4. Three Checks Before Replacement

• Check the projector panel and resolution. The original lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.75-0.95:1. Use the table in Section 2 to calculate the distance for your venue dimensions. A fixed-focus lens offers no adjustment margin, and even a zoom lens should leave 10–20 cm at both ends of the range.
• Verify the mount and locking mechanism. The original lens is calibrated to the mount of the corresponding projector series. After installation, you must hear the lens lock into place. 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, take one photo each of the projector nameplate and the existing lens nameplate and send them to us. Verification against the physical items is the safest approach.
