Barco R9010091 Zoom Standard-Throw Lens for F400-4K

Barco Original Lens R9010091 Zoom is an original optical accessory for Barco professional projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 0.95-1.30:1. The official compatibility list covers 1 projector model. Before installation, simply verify the projector model and panel size; there is no need to make do with adapter rings. The value of an original lens lies not in the extra rows of figures in a specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all match the intended design specifications, eliminating the need to compensate for image quality with keystone correction.

1. Lens Specifications

The manufacturer's factory specifications take precedence over the above specifications. Mechanical dimensions, flange distance, and mount type are not listed in the table. Please provide your projector model so we can verify them; ordering based only on a similar model 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 original lens is a zoom lens (0.95-1.30:1), so a given image size corresponds to a range of installation distances. It can focus anywhere within that range.

These figures represent the clear distance from the front of the lens to the screen and do not include the space behind the chassis for ventilation and cable connections. They are calculated for a 16:10 image; actual distances should be confirmed through on-site measurements and the manufacturer's manual.

Image quality differs 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 reduced. Where the venue allows, the middle of the range is recommended. After installation, first find the sharpest setting on the focus ring, then fine-tune the lens shift.

3. Compatible Models (1 Projector)

The following table is taken from the official compatibility list. Brightness and resolution are populated from the model database; unavailable values are shown as “—” and are not estimated.

For compatibility with a model not on the list, 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 by Projector Series

The nominal throw ratio of the same R9010091 Zoom varies by projector series. When selecting a lens, use the value for 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 cover the full panel, resulting in vignetting or edge illumination loss.
• Calculate the installation distance first. The nominal throw ratio of this lens is 0.95-1.30:1. Use the table in Section 2 to calculate the distance based on your venue's dimensions. A fixed-focus lens provides no adjustment margin, and even a zoom lens requires 10–20 cm of margin at both ends of the range.
• Check the mount and locking mechanism. Original lenses are calibrated to the mount of the corresponding projector series. After installation, you must hear the lens click into the locked position. A skewed image or soft edges usually indicate that the lock is not fully engaged, rather than a problem with the lens itself.

If you are unsure, take a photo of the projector nameplate and the existing lens nameplate and send both to us. Checking the actual hardware is the most reliable approach.
