Barco R9803076 ILD Short Fixed Short-Throw Lens: Compatible with 9 Models Including I600-4K10

Barco Original Lens R9803076 ILD Short Fixed is a genuine optical accessory for Barco large-venue projectors. It is a short-throw lens with a throw ratio of 0.50:1. The original compatibility list covers 9 projector models; before installation, simply verify against the projector model and panel size — no adapter rings needed. The value of an original lens is not a few extra rows of numbers in the spec sheet, but the fact that it is calibrated at the factory to the optical path and bayonet of that projector series: once mounted, the image circle, edge illumination, and focus travel are all at their design values, with no need to compensate image quality via keystone correction.

1. Lens Specifications

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and bayonet type not shown in the spec table, please verify with us against your projector model — ordering based on model similarity alone carries the risk of incompatibility.

2. Converting Throw Ratio to Installation Distance

Throw ratio is the ratio of installation distance to image width. This original lens is fixed-focal (0.50:1), so the installation distance changes linearly with image size and has no adjustment margin — it must be measured accurately before installation.

The above figures are the clear distance from the lens front to the screen, excluding rear ventilation and cabling space behind the projector body. Calculated at 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.

3. Compatible Models (9)

The table below is taken from the original compatibility list; brightness and resolution are filled in from the model database, with "—" where unavailable — no speculation.

To check whether models outside this list are compatible, please send us photos of the projector nameplate and the existing lens for verification — same-generation platforms often share a bayonet, but ordering based on model similarity is not worth the risk.

Throw Ratios Across Model Series

The same R9803076 ILD Short Fixed mounted on the following series does not have the same nominal throw ratio; selection must be based on the actual series of the projector body.

4. Three Things to Confirm Before Replacement

• Confirm the projector chip and resolution. Original lenses are designed for specific panel sizes; with a different panel specification, the image circle cannot cover the screen, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.50:1; apply it to your venue dimensions using the table in Section 2. Fixed focal length has no margin; even for zoom lenses, leave 10–20 cm at both ends.
• Check the bayonet and locking. Original lenses are calibrated to the bayonet of that projector series; after mounting, you must hear it lock into place. Skewed images and soft edges are usually caused by incomplete locking, not by the lens itself.

If unsure, take a photo of the projector nameplate and the existing lens nameplate and send them to us — verification against the actual hardware is the safest approach.
