WE211 Projector Lens 0.52–0.64:1 for Sharp XG-EC500UA, EC550XA, EC600UA, EC650XA

WE211 is a short-throw lens for 0.64-inch panels (Sharp), with a 0.52–0.64:1 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.

1. Lens Specifications

Lens shift is the key differentiator of this lens. Its shift range of ±18% horizontally and ±13% vertically allows the projector to be installed off-center relative to the screen centerline, with lens shift bringing the image back into alignment without keystone correction. Keystone correction comes at a cost—each adjustment reduces effective resolution and softens text edges. In professional installations, never use keystone correction when lens shift can solve the problem; preserving image quality is non-negotiable.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This is a zoom lens (0.52–0.64:1), so a given image size corresponds to a range of distances, and the lens can focus anywhere within that range.

These figures represent the clear distance from the front surface of the lens to the screen and do not include clearance behind the chassis for heat dissipation and cabling. Values are calculated for a 16:10 image; actual measurements and the manual take precedence.

Image quality differs at the two ends of the zoom range: toward the near end, the image is brighter and the edges are slightly softer; toward the far end, the edges are sharper and brightness decreases slightly. When site conditions allow, use the middle of the range. After installation, first set the focus ring to the sharpest position, then fine-tune the lens shift—adjusting both variables at once makes precise alignment difficult.

3. Compatible Models (4 Sharp Models)

The table below is ordered by model production date, from newest to oldest, and lists the resolution, brightness, and zoom ratio of each model's original lens for quick selection according to project requirements.

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

Common Features of These Models

The original standard lenses for these 4 models mostly have throw ratios in the 1.4-2.28：1 range. The 0.52–0.64:1 model featured here effectively changes the focal range, enabling different image sizes 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 aligned after the focal range is changed.

4. Three Checks Before Replacement

• Make sure the panel size and resolution match. This model is compatible with 0.64-inch panels. Projectors with a different panel size or resolution may vary in projection performance; the safest approach is to check the chassis nameplate before installation.
• Check the interface and locking mechanism. Interfaces are generally compatible within the same platform generation, but the position of the locking tab can vary by generation. If the image is skewed or the edges are not sharp after installation, the lock is usually not fully engaged; this is not typically a problem with the lens itself.
• Include lens-shift margin in the installation plan. The shift range provides installation flexibility, but edge image quality declines when it is pushed to the limit. In practice, keep lens shift within 70% of the rated value.

For compatibility with a model not on the list, the safest approach is to send us the chassis nameplate and photos of the original lens for verification—same-generation platforms often share interfaces, but ordering based solely on a similar model designation carries unnecessary risk.
