WF202 Projector Lens 0.5:1 for Optoma ZU506T, EL500U and 2 Other Models

WF202 is a short-throw lens for the 0.65/0.66/0.67 panel group (Optoma), with a throw ratio of 0.5:1. It is compatible with 2 models across 1 model series. This guide presents the lens specifications, installation distances, model compatibility list, and replacement considerations 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 focal length (0.5:1), so the installation distance varies linearly with the image size, with no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front surface of the lens to the screen and do not include clearance for rear housing ventilation or cabling. They are calculated for a 16:10 aspect ratio; actual values depend on on-site measurements and the user manual.

III. Compatible Models (2 Models, Optoma)

The table below is ordered from newest to oldest by model production date and includes each model’s resolution, brightness, and factory-lens zoom ratio for quick selection according to project requirements.

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

Common Features of These Models

The factory-installed standard lenses for both models generally have throw ratios within the 1.4:1 ~ 2.24:1 range. The 0.5:1 model featured here changes the effective focal range, producing a different image size from the same projection distance—the direct reason for replacing the lens. It also retains full lens-shift capability, so the image can still be aligned after adjusting the focal range.

IV. Three Checks Before Replacement

• The panel and resolution must match. This model is designed for a 0.65-inch panel. Projectors with a different panel size or resolution may produce different projection performance, so it is best to verify the specifications against the nameplate on the projector before installation.
• Check the interface and locking mechanism. Interfaces on platforms of the same generation are generally compatible, but locking latch positions vary between generations. If the image appears skewed or the edges look unfocused after installation, the cause is usually incomplete locking rather than an issue with the lens itself.
• A fixed-focus lens has no zoom adjustment. The image size can only be changed by moving the projector. The venue dimensions must be measured accurately in advance, with an additional 10–20 cm left at each endpoint.

For models not included in the list, the safest option is to send us the projector nameplate and a photo of the original lens for verification. Platforms of the same generation often share the same interface, but placing an order based solely on similar model names is not worth the risk.
