Barco R9862005 Short Zoom Lens Fits 23 Models: HDX-4K14, HDX-4K20 FLEX, HDX-W12, HDX-W14, HDX-W18

Genuine Barco Lens R9862005 Short Zoom is a factory-supplied optical accessory for Barco professional projectors. It provides a standard throw (Standard Throw) with a throw ratio of 1.17-1.50:1. Barco's official model compatibility list covers 23 projector models. Before installation, simply verify the projector model and panel size; there is no need to resort to 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 mount of that projector series. Once installed, the image circle, edge illumination, and focus travel all match their design values, eliminating the need to use keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type are not listed in the specification table. Please send us the projector model so that we can verify them. Ordering solely because two models appear similar carries the risk that the lens will not fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This genuine lens is a zoom lens (1.17-1.50:1), so a given image size corresponds to a range of installation distances. It can be focused anywhere within that range.

These distances represent the clear distance from the front of the lens to the projection screen and do not include space behind the projector for cooling and cable connections. They are calculated for a 16:10 image; actual distances should be verified on site and are subject to the manufacturer's manual.

Image quality varies 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 is slightly lower. Where the venue allows, use a position near the middle of the range. After installation, first find the sharpest position on the focus ring, then fine-tune the lens shift.

3. Compatible Models (23 Models)

The table below is taken from the official model compatibility list. Brightness and resolution are populated from the model database; unavailable specifications are shown as “—”, with no assumptions made.

For models not included in the list, please send us photos of the projector nameplate and the existing lens so that we can verify compatibility—platforms from the same generation often share the same mount, but placing an order based solely on a similar model name is not worth the risk.

Throw Ratio by Model Series

The nominal throw ratio of the same R9862005 Short Zoom varies across the series listed below. Select the value based on the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector panel and resolution.A genuine lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full panel, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first.This lens has a nominal throw ratio of 1.17-1.50:1. 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 still allow an additional 10–20 cm at both ends.
• Check the mount and locking mechanism.A genuine lens is calibrated to the mount of the applicable projector series, and you must hear it lock into place after installation. A skewed image or soft edges are usually caused by an incomplete lock, not by 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 most reliable approach.
