Barco R9802185 GC Zoom Long-Throw Lens Guide for G100-W16 G100-W19 G100-W22 G100-W25

Barco Original Lens R9802185 GC Zoom is an OEM optical accessory for Barco engineering projectors. It is a Long Throw lens with a throw ratio of 2.00-4.00:1. The official compatibility list covers 4 models. Before installation, simply verify the projector model and panel size; adapter rings are not needed. The value of an original lens lies not in the extra rows of figures in a specification sheet, but in its factory calibration to the optical path and mount of the relevant projector series. Once installed, the image circle, edge illumination, and focus travel all meet their design values, without relying on keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification sheet, please verify them with us using the projector model. Placing an order solely because the model is similar 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 original lens is a zoom lens (2.00-4.00:1). A single image size corresponds to a range of installation distances, and the lens can focus anywhere within that range.

The distances above are clear measurements from the front face of the lens to the screen and do not include space behind the projector for cooling and cable connections. They are calculated for a 16:10 image; actual values are subject to on-site measurements and the original manufacturer's manual.

Image quality differs at the two ends of the zoom range: the image is brighter and the edges are slightly softer near the close end, while the edges are sharper and brightness is slightly lower near the far end. When site conditions allow, use the middle of the range. After installation, first find the sharpest setting on the focus ring, and then fine-tune the lens shift.

3. Compatible Models (4 Units)

The following table is taken from the official compatibility list. Brightness and resolution are filled in from the model database; unavailable values are shown as "—", and no assumptions are made.

To determine whether a model not on the list is compatible, send us photos of the projector nameplate and existing lens for verification. Platforms of the same generation often share a 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 R9802185 GC Zoom is installed. For lens selection, use the value corresponding to the series of the actual projector.

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 light loss at the edges after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 2.00-4.00:1. Apply the table in Section 2 to your site dimensions. Fixed-focus lenses offer no margin, while zoom lenses should also leave 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism. Original lenses are calibrated to the mount of the relevant projector series. You must hear the lens lock into place after installation. Image skew and soft edges are usually caused by incomplete locking, not a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one photo of the existing lens label and send them to us. Verifying against the actual hardware is the most reliable approach.
