Barco R9862001 Ultra Short Zoom Lens for 27 Compatible Models

Barco Original Lens R9862001 Ultra Short Zoom is an OEM optical accessory for Barco engineering projectors. It features a standard throw (Standard Throw) with a throw ratio of 0.73-0.94:1. The OEM compatibility list covers 27 models; before installation, simply verify the projector model and panel size, with no need for adapter rings. The value of an OEM lens lies not in the additional figures on a specification sheet, but in the fact that its optical path and mount are calibrated at the factory for that projector series. Once installed, the image circle, edge illumination, and focus travel all operate at 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 official manufacturer specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please verify them with us based on the projector model. Placing an order solely on the basis of a similar model number carries the risk that the lens will not fit.

2. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (0.73-0.94:1), so a given image size corresponds to a range of installation distances. It can focus at any position within that range during installation.

The figures above represent the clear distance from the front surface of the lens to the projection screen and do not include space for rear projector ventilation or cable connections. They are calculated for a 16:10 image; actual distances should be verified on site and according to the manufacturer's manual.

Image quality differs at the two ends of the zoom range: the image is brighter with slightly softer edges near the close end, while the edges are sharper with slightly lower brightness near the far end. Where the venue allows, the middle of the range is recommended. After installation, first find the sharpest focus position using the focus ring, and then fine-tune the lens shift.

3. Compatible Models (27 Models)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution values are populated from the model database; unavailable values are marked “—” and have not been estimated.

For models not included in the list, send us photos of the projector nameplate and existing lens so we can verify compatibility. Platforms from the same generation often share a mount, but the risk of ordering based solely on a similar model number is not worth taking.

Throw Ratios for Different Model Series

The rated throw ratio varies by model series when the same R9862001 Ultra Short Zoom lens is used. When selecting a lens, use the value corresponding to the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. The OEM lens is designed for a specific panel size. If the panel specification differs, its image circle cannot cover the full image area, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 0.73-0.94:1. Use the table in Section 2 to calculate the distance based on your venue dimensions. A fixed lens offers no adjustment margin, and even a zoom lens requires 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount for that projector series. You must hear it click into the locked position after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with 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. Verification against the actual equipment is the most reliable approach.
