Barco R9802186 GC Zoom Long-Throw Projector Lens Guide: G100-W16 G100-W19 G100-W22 G100-W25

Barco Genuine Lens R9802186 GC Zoom is an OEM optical accessory for Barco professional projectors. It is a long-throw lens with a throw ratio of 4.00-7.20:1. The OEM compatibility list covers 4 models; before installation, simply verify the projector model and panel size, with no need to resort to adapter rings. The value of an OEM lens lies not in the extra rows of numbers in the specification sheet, but in the fact that it is calibrated at the factory to the optical path and mount of the projector series. Once installed, the image circle, edge illumination, and focus travel all match their design values, so there is no need to rely on keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications table, please contact us with your projector model for verification. Ordering solely based on a similar model carries the risk that the lens will not fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This OEM lens has a zoom range of 4.00-7.20:1, so a given image size corresponds to a range of installation distances, and the lens can be focused anywhere within that range.

The distances above are clear distances from the front surface of the lens to the screen and do not include space for cooling and cable connections behind the projector. These figures are calculated for a 16:10 image; actual values should be confirmed by on-site measurement and the OEM manual.

Image quality differs at the two ends of the zoom range: near the short end, the image is brighter and the edges are slightly softer; near the long end, the edges are sharper and brightness decreases slightly. Where the venue allows, we recommend positioning the lens near the middle of the range. After installation, find the sharpest setting on the focus ring, then fine-tune the lens shift.

3. Compatible Models (4 Units)

The table below is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; values that cannot be retrieved are marked “—” and have not been estimated.

For a model not included in the list, send us photos of the projector nameplate and the current lens for compatibility verification. Same-generation platforms often share a mount, but ordering based on a similar model number is not worth the risk.

Throw Ratio by Model Series

The nominal throw ratio varies by projector series when the same R9802186 GC Zoom is installed. Select the value based on the series of the projector in use.

4. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution.OEM 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 4.00-7.20:1; use the table in Section 2 to match your venue's dimensions. Fixed-focus lenses offer no adjustment margin, and even a zoom lens needs 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism.The OEM lens is calibrated to the mount of the relevant projector series. After installation, you must hear the lens click into the locked position. 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 photo of the existing lens nameplate and send them to us. Verification against the actual hardware is the safest approach.
