Barco R9802235 High Performance Ultra Wide Zoom Standard Throw Lens: Medea Compatibility

Barco original lens R9802235 High Performance Ultra Wide Zoom is the factory optical accessory for Barco professional projectors, belonging to the standard throw category (Standard Throw), with a throw ratio of 1.26-1.72:1. The factory compatibility list covers 1 model; before installation, simply verify the projector model and panel size — no need to improvise with adapter rings. The value of an original lens lies not in a few extra numbers on the spec sheet, but in the fact that it is calibrated at the factory to the optical path and mount of that model series: once fitted, the image circle, edge illumination, and focusing travel are all at their design values, so there is no need to patch up image quality with keystone correction.

1. Lens Specifications

The above specifications are subject to the factory specifications. For mechanical dimensions, flange distance, and mount type not shown in the table, please check with us using the projector model; ordering directly on the strength of a similar model number carries the risk of a lens that simply will not fit.

2. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This original lens is a zoom (1.26-1.72:1), so each image size corresponds to a range of distances, and any mounting position within that range will focus properly.

These figures are the clear distance from the front of the lens to the screen, and do not include the cooling and cabling space behind the chassis. Calculated for a 16:10 image; in practice, on-site measurement and the factory manual take precedence.

Image quality differs at the two ends of the zoom range: near the close end the image is brighter with slightly softer edges; near the far end the edges are tighter and brightness drops slightly. Where the room allows, it is recommended to place the projector in 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 (1 Unit)

The table below is taken from the factory compatibility list; brightness and resolution are backfilled from the model database, and entries that cannot be retrieved are shown as "—"; no assumptions are made.

For models outside the list, please send us a photo of the projector nameplate and of the existing lens so we can verify compatibility — platforms of the same generation often share the same mount, but the risk of ordering on the strength of a similar model number is not worth taking.

Throw Ratios by Model Series

The nominal throw ratio is not the same when the same R9802235 High Performance Ultra Wide Zoom is fitted to the series below; take the value from the series that your actual projector belongs to.

4. Three Checks Before Replacement

• Confirm the projector panel and resolution. Original lenses are designed for a specific panel size; if the panel specification differs, the image circle cannot cover the frame, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.26-1.72:1; apply the table in Section 2 to your own room dimensions. A fixed-focus lens leaves no margin, and even with a zoom you should allow 10–20 cm at both ends.
• Verify the mount and the lock. Original lenses are calibrated to the mount of that model series, and after fitting you must hear the lock engage; a skewed image or soft edges are usually caused by the lens not being fully locked, not by a fault in the lens itself.

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