Barco R9840775 Fixed Standard Projector Lens for 23 Models

Barco Original Lens R9840775 Fixed is a factory-supplied optical accessory for Barco professional projectors. It is a standard-throw (Standard Throw) lens with a 1.20:1 throw ratio. The factory compatibility list covers 23 models, so simply verify the projector model and panel size before installation—no adapter ring workaround is needed. The value of an original lens lies not in the additional figures in its specifications, but in the fact that it is calibrated at the factory to the optical path and lens mount of that model series. Once installed, the image circle, edge illumination, and focus travel are all at their design values, eliminating the need for keystone correction to compensate for image quality.

I. Lens Specifications

Brand	Barco (Barco)
Lens Model	R9840775 Fixed
Throw Ratio	1.20:1
Product Type	Standard Throw (Standard Throw)
Compatible Models	23 models
Warranty	12 months; after-sales service is available for defects other than accidental damage, based on the date shown on the shipping invoice

The above specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications, please verify them with us using the exact projector model. Placing an order based solely on similar model names carries the risk of the lens not fitting.

II. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This original lens has a fixed focal length (1.20:1). Installation distance varies linearly with image size, with no adjustment margin, so accurate measurements are essential before installation.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 2.58 m
120 inches	2.58 m	Approx. 3.10 m
150 inches	3.22 m	Approx. 3.87 m
200 inches	4.30 m	Approx. 5.16 m

These distances represent the clear space from the front surface of the lens to the screen and do not include room for cooling and cable connections at the rear of the projector. The figures are calculated for a 16:10 image; actual values should be confirmed through on-site measurements and the manufacturer's manual.

For compatibility with models not listed, please send us photos of the projector nameplate and the existing lens. Platforms from the same generation often share the same mount, but ordering based solely on similar model names is not worth the risk of incompatibility.

Throw Ratio by Model Series

The nominal throw ratio differs by series when the same R9840775 Fixed lens is installed. Select the value based on the series of the actual projector.

Model Series	Throw Ratio
—	1.20:1

IV. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. The original lens is 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. The nominal throw ratio of this lens is 1.20:1; use the table in Section II to calculate the distance for your installation site. A fixed-focal-length 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 original lens is calibrated to the mount used by projectors in that series. After installation, you must hear it lock into place. A skewed image or soft edges usually indicate that the lens is not fully locked, 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 hardware is the safest approach.
