WA102 Projector Lens 0.75:1 for 4 Barco Models: G100-W16, G100-W19, G100-W22, G100-W25

WA102 is a short-throw lens for 0.96-inch panels (Barco), with a 0.75:1 throw ratio and lens shift. It is compatible with 4 projector models across 1 model series. This article presents the lens specifications, installation distances, model compatibility list, and replacement considerations in one place.

I. Lens Specifications

Lens shift capability is the key differentiator of this lens. A shift range of 21.00% horizontally and 8.20% vertically allows the projector to be installed off the screen's central axis, with lens shift used to reposition the image without requiring keystone correction. Keystone correction comes at a cost—each adjustment step sacrifices some effective pixels and makes text edges appear soft. In engineering installations, never use keystone correction when lens shift can resolve the issue; this is the baseline for image quality.

II. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of installation distance to image width. This is a fixed-focal-length lens (0.75:1), so the installation distance changes linearly with image size, with no adjustment allowance. Accurate measurements are essential before installation.

The distances above are the clear distances from the front surface of the lens to the screen and do not account for rear housing clearance for heat dissipation or cable connections. The calculations are based on a 16:10 image; actual distances should be confirmed through on-site measurements and the manual.

III. Compatible Models (4 Models, Barco)

The table below is ordered from newest to oldest by model production date and lists each model's resolution, brightness, and factory-standard lens zoom ratio, enabling quick identification according to project requirements.

Common Features of These Models

The standard factory lens throw ratios for the 4 models vary, with most indicated as Depends on the lens. The 0.75:1 model covered in this article effectively adjusts the focal range, allowing the same projection distance to produce different image sizes—this is the direct reason for replacing the lens. It also retains full lens shift capability, so the image can still be aligned after the focal range is adjusted.

IV. Three Things to Confirm Before Replacement

• The panel and resolution must match. This model is designed for 0.96-inch panels. Projectors with different panel sizes or resolutions may vary in projection performance; the most reliable approach is to verify the specifications against the projector nameplate before installation.
• Check the interface and locking mechanism. Interfaces are generally compatible across platforms of the same generation, but the position of the locking catch varies between generations. If the image appears skewed or the edges look soft after installation, the most likely cause is an incompletely engaged lock rather than an issue with the lens itself.
• Allow for lens shift margin in the installation plan. The shift range provides installation flexibility, but edge image quality degrades when the lens is pushed to its limit. In practice, keep lens shift within 70% of the nominal values.

For models not included in the list, it is safest to send us a photo of the projector nameplate and the original lens for verification—platforms of the same generation often share the same interface, but the risks of ordering based on a similar model designation are not worth taking.
