Barco R9803070 ILD Zoom Standard-Throw Lens Fits 9 Projector Models

Barco Original Lens R9803070 ILD Zoom is an original optical accessory for Barco engineering projectors. It is a standard throw (Standard Throw) lens with a throw ratio of 1.00-1.40:1. The original compatibility list covers 9 models. Before installation, simply verify the projector model and panel size; no adapter ring is needed. The value of an original lens lies not in the extra numbers on a specification sheet, but in the fact that it is factory-calibrated to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all match the design values, eliminating the need to use keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the original manufacturer’s specifications. Mechanical dimensions, flange distance, and mount type are not shown in the specification table; please verify them with us using the projector model. Ordering based solely on a similar model carries the risk that the lens will not fit.

2. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This original lens is a zoom lens (1.00-1.40:1), so the same image size corresponds to a range of distances, and it can focus anywhere within that range.

The distances above are clear distances from the front surface of the lens to the screen and do not account for space behind the projector for heat dissipation and cable connections. These figures are calculated for a 16:10 image; actual values must be confirmed by on-site measurements and the original manufacturer’s manual.

Image quality differs at the two zoom extremes: near the close end, the image is brighter and the edges are slightly softer; near the far end, the edges are sharper and brightness is slightly lower. Where the venue allows, placing the lens near the middle of the range is recommended. After installation, first find the sharpest position on the focus ring, then fine-tune the lens shift.

3. Compatible Models (9 Models)

The following table is taken from the original compatibility list. Brightness and resolution have been populated from the model database; entries that cannot be verified are marked “—”, and no values have been guessed.

For a model not on the list, please send us photos of the projector nameplate and the existing lens for verification. Platforms of the same generation often share the same mount, but the risks of ordering based on a similar model outweigh the convenience.

Throw Ratios by Model Series

When the same R9803070 ILD Zoom lens is installed on the series listed below, the nominal throw ratio differs. Select the value based on the actual projector series.

4. Three Checks Before Replacement

• Confirm the projector’s imaging chip and resolution. Original lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 1.00-1.40:1. Use the table in Section 2 to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, while a zoom lens should also allow an additional 10–20 cm at both ends.
• Check the mount and locking mechanism. The original lens is calibrated to the mount of that projector series. After installation, you must hear it 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 of the existing lens nameplate and send them to us. Verification against the actual items is the safest approach.
