WA106 0.75:1 Projector Lens for Christie C-WU2000L and 1 Other Model

WA106 is a short-throw lens for 0.96-inch panels (KINYIN), with a 0.75:1 throw ratio and lens shift. It is compatible with 1 model across 1 model series. This article clearly presents the lens specifications, installation distances, model compatibility list, and replacement considerations in one place.

I. Lens Specifications

Lens shift is the key differentiator of this lens. With a shift range of 21.00% horizontally and 8.20% vertically, the projector can be installed off the screen center axis and the image can be repositioned using lens shift without relying on keystone correction. Keystone correction comes at a cost—each correction step sacrifices some effective pixels and can blur text edges. In professional installations, lens shift should always be used instead of keystone correction whenever possible, as preserving image quality is essential.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. As this is a fixed-zoom lens (0.75:1), the installation distance varies linearly with image size, leaving no room for adjustment. Accurate measurements are essential before installation.

The distances above are clear distances from the front of the lens to the screen and do not include space behind the projector for ventilation and cable connections. Values are calculated for a 16:10 image; actual distances should be confirmed by on-site measurement and the manual.

III. Compatible Models (1 Model, KINYIN)

The following table is ordered from newest to oldest by model production date and includes each model's resolution, brightness, and factory-standard lens zoom ratio, making it easy to identify the right option for project requirements.

The zoom ratio is the zoom factor of the model's factory-standard lens (upper limit ÷ lower limit of the standard throw-ratio range), not the zoom range of the lens featured in this article.

Common Characteristics of These Models

The factory-standard lenses for this model generally have throw ratios concentrated around 1.5~2.0. The 0.75:1 ratio of the lens featured in this article effectively changes the focal-length range, allowing a different image size from the same projection distance—this is the direct reason for replacing the lens. Full lens-shift capability is retained, so the image can still be properly aligned after changing the focal range.

IV. Confirm Three Things Before Replacement

• Panel size and resolution must match. This model is designed for 0.96-inch panels. Projectors with a different panel size or resolution may exhibit differences in projection performance; checking the projector's nameplate before installation is the most reliable approach.
• Interfaces and locking mechanism. Interfaces are generally shared across platforms of the same generation, but locking latch positions differ between generations. If the image appears skewed or the edges look soft after installation, the lock is usually not fully engaged rather than there being a problem with the lens itself.
• Lens-shift allowance must be included in installation planning. The shift range provides some installation flexibility, but image quality at the edges declines when the limits are reached. For actual use, operation should remain within 70% of the nominal values.

For a model not on the list, the safest approach is to send us a photo of the projector's nameplate and original lens for verification. Platforms of the same generation often share interfaces, but the risk of ordering based on a similar model designation is not worth taking.
