Barco R9862040 Extra Long Zoom Lens Guide: Compatible with 33 Models

Barco Original Lens R9862040 Extra Long Zoom is an original optical accessory for Barco professional projectors. It is a long-throw lens with a throw ratio of 4.50-7.50:1. Barco's official compatibility list covers 33 models, allowing you to verify the projector model and panel size before installation without resorting to adapter rings. The value of an original lens lies not in the additional rows of specifications, but in its factory calibration to the optical path and lens mount of the corresponding model series: once installed, image circle coverage, edge illumination, and focusing range all meet their specified values, so there is no need to compensate for image quality with keystone correction.

I. Lens Specifications

These specifications are subject to Barco's official specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please provide your projector model so that we can verify them. Ordering based solely on a similar model carries the risk that the lens will not fit.

II. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of installation distance to image width. This original lens is a zoom lens (4.50-7.50:1), so a given image size corresponds to a range of installation distances. It can focus anywhere within that range.

These figures show the clear distance from the front of the lens to the projection screen and do not allow for cooling and cable-connection space at the rear of the projector. They are calculated for a 16:10 image; for actual installation, site measurements and the manufacturer's manual take precedence.

Image quality varies between the two ends of the zoom range: toward the shorter-throw end, the image is brighter and the edges are slightly softer; toward the longer-throw end, the edges are sharper and brightness decreases slightly. Where the venue allows, it is recommended to use the middle of the range. After installation, first find the sharpest position using the focus ring, then fine-tune the lens shift.

III. Compatible Models (33 Models)

The following table is taken from Barco's official compatibility list. Brightness and resolution have been populated from the model database; where the data is unavailable, “—” is shown, with no values inferred.

For compatibility with a model not listed, please send us photos of the projector nameplate and the existing lens for verification—although platforms of the same generation often share the same mount, ordering based on a similar model is not worth the risk.

Throw Ratios by Model Series

The rated throw ratio of the same R9862040 Extra Long Zoom differs across the series listed below. Select the ratio based on the actual projector series.

IV. Three Checks Before Replacement

• Verify 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 cover the full image, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. This lens has a rated throw ratio of 4.50-7.50:1; apply the table in Section II to your venue dimensions. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires an additional 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism. The original lens is calibrated to the mount of that model series. After installation, you must hear the lock engage; a skewed image or soft edges are usually caused by an incompletely engaged lock, rather than a problem with the lens itself.

If you are unsure, take one photo of each nameplate—the projector and the existing lens—and send them to us. Verification against the physical items is the most reliable approach.
