Barco R9802242 Zoom Telephoto Lens: Medea Compatibility

Barco Original Lens R9802242 Zoom is an original optical accessory for Barco professional projectors. It is a long-throw (Long Throw) lens with a throw ratio of 1.58-2.25:1. The official compatibility list covers 1 model, so before installation, simply verify the projector model and panel size—no adapter ring workaround is needed. The value of an original lens lies not in the extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series: the image circle, edge illumination, and focus travel all meet their design specifications, eliminating the need to use keystone correction to compensate for image quality.

I. Lens Specifications

These specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not shown in the specifications table, please contact us with the projector model for verification. Ordering directly based on a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This original lens is a zoom lens (1.58-2.25:1), so a given image size corresponds to a range of distances; during installation, the lens can focus at any distance within that range.

The distances above are clear distances from the front surface 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 distances should be confirmed by on-site measurement and in accordance with the manufacturer's manual.

Image quality differs at the two ends of the zoom range: at the near end, the image is brighter and the edges are slightly softer; at the far end, the edges are sharper and brightness decreases slightly. Where the installation site allows it, use the middle of the range, and after installation, first find the sharpest position using the focus ring, then fine-tune the lens shift.

III. Compatible Models (1 Projector)

The table below is taken from the official compatibility list. Brightness and resolution are populated from the model database; entries that cannot be obtained are marked “—” and are not guessed.

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

Throw Ratios for Different Projector Series

The nominal throw ratio varies among the following series when the same R9802242 Zoom is installed; use the value for the series of the actual projector when selecting a lens.

IV. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. The original lens is 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 rated throw ratio of 1.58-2.25:1. Use the table in Section II to calculate the distance for your installation site. A fixed-focus lens offers no adjustment margin, while a zoom lens should also allow 10–20 cm at both ends of the range.
• Verify the mount and locking mechanism. The original lens is calibrated to the mount of that projector series, and you must hear it lock into place after installation. A skewed image or soft edges are usually caused by incomplete locking, not by the lens itself.

If you are unsure, take one photo each of the projector nameplate and the existing lens nameplate and send them to us. Checking the details against the actual hardware is the safest approach.
