Barco R9803077 ILD Short Fixed UST Lens: Fits 9 Models

Barco Original Lens R9803077 ILD Short Fixed is a genuine optical accessory for Barco professional projectors, featuring an ultra-short-throw (Ultra Short Throw) design and a throw ratio of 0.37:1. The factory compatibility list covers 9 models. Before installation, simply verify the projector model and panel size; no adapter rings are needed. The value of a genuine lens lies not in the extra figures in a specification sheet, 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 focusing travel all meet their design specifications, so there is no need to compensate for image quality with keystone correction.

I. Lens Specifications

The above specifications are subject to the official manufacturer specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please verify them with us using the exact projector model. Placing an order solely because the model appears similar carries the risk of a lens that will not fit.

II. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This genuine lens has a fixed focus (0.37:1), so the installation distance varies linearly with image size and offers no adjustment margin. Accurate measurements are essential before installation.

The distances shown are clear distances from the front surface of the lens to the projection screen and do not include clearance at the rear of the projector for ventilation and cable connections. These figures are calculated for a 16:10 image; actual values should be confirmed through on-site measurements and the manufacturer's manual.

III. Compatible Projector Models (9 Models)

The table below is taken from the factory compatibility list. Brightness and resolution have been populated from the model database; where the data is unavailable, “—” is shown, and no assumptions have been made.

For compatibility with a model not included in the list, please send us a photo of the projector nameplate and the existing lens for verification. Platforms from the same generation often share the same mount, but the risk of ordering based solely on a similar model is not worth taking.

Throw Ratio by Projector Model Series

The nominal throw ratio varies by series when the same R9803077 ILD Short Fixed is installed on the following series. Select the value according to the series of the actual projector.

IV. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. The original lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full area, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.37:1. Use the table in Section II to determine the required distance for your installation site. A fixed-focus lens offers no adjustment margin; even with a zoom lens, allow 10–20 cm at both ends.
• Verify the mount and locking mechanism. The original lens is calibrated to the mount of that projector series and must be heard locking securely into place after installation. A skewed image or soft edges are usually caused by incomplete locking, rather than a problem with the lens itself.

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