Barco R9832741 Fixed Standard Lens for MSWU-81E, RLM-W6 & RLM-W8

Barco Genuine Lens R9832741 Fixed is an original optical accessory for Barco engineering projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 1.16:1. The official compatibility list covers 3 models; before installation, simply verify the projector model and panel size, with no need to make do with adapter rings. The value of a genuine lens lies not in the extra figures in the specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that projector series. Once installed, the image circle, edge illumination, and focus travel all match the design values, so keystone correction is not needed to compensate for image quality.

1. Lens Specifications

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

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This genuine lens has a fixed focal length (1.16:1), so the installation distance varies linearly with image size, with no adjustment margin. Accurate measurements are essential before installation.

These values represent the clear distance from the lens face to the screen and do not include clearance behind the projector for heat dissipation and cable connections. They are calculated for a 16:10 image; actual distances should be confirmed by on-site measurement and the manufacturer's manual.

3. Compatible Models (3 Models)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution are populated from the model database; where data is unavailable, “—” is shown rather than estimated.

For models not on the list, please send us photos of the projector nameplate and existing lens so we can verify compatibility. Projector platforms from the same generation often share the same mount, but ordering based solely on a similar model number carries avoidable risk.

Throw Ratio by Projector Series

The nominal throw ratio of the same R9832741 Fixed lens varies by projector series. Use the value corresponding to the actual projector series when selecting a lens.

4. Three Checks Before Replacement

• Confirm the projector chipset and resolution. Genuine lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.16:1. Use the table in Section 2 to calculate the distance for your installation space. A fixed-focus lens offers no adjustment margin; even with a zoom lens, allow an extra 10–20 cm at both ends.
• Verify the mount and locking mechanism. The genuine lens is calibrated to the lens mount for that projector series and must audibly click into the locked position after installation. Image skew or soft image edges is 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, and send them to us for verification. Comparing them with the actual equipment is the safest approach.
