WF201 Projector Lens 0.5:1 for 2 Acer Models: LU-P500UT, P500WA

WF201 is a short-throw lens for the 0.65/0.66/0.67 panel group (Acer), with a throw ratio of 0.5:1. It is compatible with 2 models in 1 model series. This article presents the lens specifications, installation distance, model compatibility list, and replacement considerations all in one place.

I. Lens Specifications

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This lens has a fixed focus (0.5:1), so the installation distance varies linearly with image size, with no adjustment margin. Accurate measurements are essential before installation.

The above figures represent the clear distance from the front of the lens to the screen and do not include space for rear chassis cooling or cable connections. These values are calculated for a 16:10 image; actual distances should be verified through on-site measurements and the manual.

III. Compatible Projector Models (2 Models, Acer)

The table below is arranged by model production date, from newest to oldest. It lists the resolution, brightness, and standard lens zoom ratio of each model for quick identification based on project requirements.

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

Common Features of These Models

The factory-standard lenses for these 2 models generally have throw ratios concentrated around 1.4-2.24. The 0.5:1 model featured here effectively shifts the focal length range, allowing different image sizes at the same projection distance—the direct reason for replacing the lens—while retaining full lens-shift capability, so the image can still be aligned after adjusting the focal length range.

IV. Three Checks Before Replacement

• Ensure the panel and resolution match. This model is designed for a 0.65-inch panel. Projectors with a different panel size or resolution may produce different projection results, so checking the rating plate on the chassis before installation is the most reliable approach.
• Check the interface and locking mechanism. Interfaces are generally interchangeable within the same platform generation, but the positions of the locking clips vary by generation. If the image appears skewed or the edges are not sharp after installation, the lock is usually not fully engaged rather than there being an issue with the lens itself.
• A fixed-focus lens offers no zoom adjustment. Image size can only be changed by moving the projector, so the site dimensions must be measured accurately first, with an additional 10–20 cm allowed at each endpoint.

For models not on the list, it is safer to send us photos of the chassis rating plate and the original lens for verification—although platforms of the same generation often share interfaces, ordering based solely on a similar model number carries unnecessary risk.
