Barco R98620103 TLD+ VHC Standard Zoom Lens for 31 Projector Models

Barco Genuine Lens R98620103 TLD+ VHC Standard Zoom is an OEM optical accessory for Barco professional projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 1.28-1.74:1. Barco's official compatibility list covers 31 models. Before installation, simply verify the projector model and panel size; there is no need to resort to adapter rings. The value of a genuine lens lies not in the extra rows of figures in the specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of the relevant projector series. Once installed, its image circle, edge illumination, and focusing travel all meet their design values, eliminating the need for keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are based on the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type are not listed in the table. Please provide the projector model so we can verify them for you. Ordering solely based 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 genuine lens is a zoom lens (1.28-1.74:1), so each image size corresponds to a range of installation distances. It can focus at any position within that range.

The values above represent the clear distance from the front surface of the lens to the screen and do not include cooling clearance or cable-connection space behind the projector. They are calculated for a 16:10 image; actual values should be verified on site and in accordance with the manufacturer's manual.

Image quality differs at the two ends of the zoom range: near the close end, the image is brighter and the edges are slightly softer; near the long end, the edges are sharper and the brightness is slightly lower. If site conditions allow, use the middle of the range. After installation, first find the sharpest setting on the focus ring, then fine-tune the lens shift.

3. Compatible Models (31 Models)

The table below is taken from Barco's official compatibility list. Brightness and resolution are populated from the model database; where the data cannot be retrieved, “—” is shown, and no values are inferred.

For compatibility with a model not on the list, send us photos of the projector nameplate and the existing lens for verification. Platforms from the same generation often share a mount, but placing an order solely because the model names are similar carries unnecessary risk.

Throw Ratio by Projector Series

The nominal throw ratio of the same R98620103 TLD+ VHC Standard Zoom varies by series, as shown below. Select the value that corresponds to the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. The genuine 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 light loss at the edges.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.28-1.74:1. Use the table in Section 2 to calculate the distance for your installation site. A fixed-focus lens has no adjustment margin, and a zoom lens also needs 10–20 cm of allowance at both ends.
• Check the mount and locking mechanism. The genuine lens is calibrated to the mount of the relevant projector series. After installation, you must hear the lens click into the locked position. A skewed image or soft edges are usually caused by incomplete locking, not by a problem with the lens itself.

If you are uncertain, take one photo of the projector nameplate and one of the existing lens nameplate, then send them to us. Verification against the actual hardware is the most reliable approach.
