Barco R9852090 Zoom Standard Throw Projector Lens: XDL-4K30 XDL-4K60 XDL-4K75 Compatible

Genuine Barco Lens R9852090 Zoom is an OEM optical accessory for Barco engineering projectors. It is a standard throw lens (Standard Throw) with a throw ratio of 1.45-1.80:1. Barco's official model compatibility list covers 3 models; before installation, simply verify the projector model and panel size, with no need to resort to adapter rings. The value of an OEM lens lies not in the extra rows of figures in a specification sheet, but in its factory calibration to the optical path and mount of the projector series. Once installed, the image circle, edge illumination, and focus travel are all at their designed values, eliminating the need to use keystone correction to compensate for image quality.

The above specifications follow the manufacturer's published specifications. For mechanical dimensions, flange distance, and mount configuration not shown in the specification table, please contact us with the projector model. Ordering based solely on a similar model carries the risk that the lens will not fit.

2. Calculating Installation Distance from Throw Ratio

Throw ratio is the ratio of installation distance to image width. This OEM lens is a zoom lens (1.45-1.80:1). For a given image size, it covers a range of installation distances and can focus at any position within that range.

Screen Size	Image Width	Required Installation Distance
100 inches	2.15 m	approx. 3.12 – 3.87 m
120 inches	2.58 m	approx. 3.74 – 4.64 m
150 inches	3.22 m	approx. 4.68 – 5.80 m
200 inches	4.30 m	approx. 6.23 – 7.74 m

The distances above represent the clear distance from the front face of the lens to the screen and do not include ventilation clearance or cable-routing space at the rear of the projector. They are calculated for a 16:10 image, and actual values should be verified through on-site measurements and the manufacturer's manual.

Image quality varies at the two ends of the zoom range: near the short-throw end, the image is brighter and the edges are slightly softer; near the long-throw end, the edges are sharper and brightness decreases slightly. Where installation conditions allow, use the middle of the range. After installation, find the sharpest position on the focus ring, then fine-tune the lens shift.

3. Compatible Models (3 Projectors)

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

Model	Brightness	Resolution
XDL-4K30	29700 lumens	4096x2160
XDL-4K60	59200 lumens	4096x2160
XDL-4K75	72600 lumens	4096x2160

For compatibility with a model not on the list, send us photos of the projector nameplate and the existing lens for verification. Projector platforms from the same generation often share a mount, but the risk of ordering based on a similar model is not worth taking.

Throw Ratio by Model Series

The nominal throw ratio for the same R9852090 Zoom varies across the projector series listed below, so use the value for the actual projector series when selecting a lens.

4. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. OEM lenses are designed for a specific panel size. If the panel specification differs, 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 rated throw ratio of 1.45-1.80:1. Use the table in Section 2 to calculate the distance for your installation space. A fixed-focus lens offers no adjustment margin, while even a zoom lens needs 10–20 cm of adjustment range at both ends.
• Verify the mount and locking mechanism. OEM lenses are calibrated to the mount used by projectors in that 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 the lens itself.

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