WD305 Projector Lens 0.5:1 for Acer LU-P600UT and 1 Other Large-Venue Projector

The WD305 is a short-throw lens designed for 0.47/0.48 panel group (Acer) projectors, with a throw ratio of 0.5:1 and lens shift. It is compatible with 1 projector model and 1 model series. This article lists the lens specifications, installation distances, model compatibility list, and replacement key points all at once.

I. Lens Specifications

II. Throw Ratio to Installation Distance Conversion

The throw ratio is the ratio of installation distance to screen width. This lens is fixed-focus (0.5:1), so the installation distance changes linearly with screen size with no adjustment margin—it must be measured accurately before installation.

The above figures are the clear distance from the lens front to the screen, excluding rear ventilation and cabling space behind the projector body. Calculated based on 16:10 aspect ratio; actual values are subject to on-site measurement and the instruction manual.

III. Compatible Models (1 unit, Acer)

The table below is sorted by model production date from newest to oldest, including each model's resolution, brightness, and original lens zoom ratio, making it easy to quickly identify the right model for project requirements.

The zoom ratio refers to the zoom factor of the model's original standard lens (upper limit ÷ lower limit of the original throw ratio range), not the zoom range of the lens described in this article.

Common Features of These Models

The original standard lens throw ratios of this model are mostly concentrated in the 1.36~2.18 range. The 0.5:1 model in this article represents an adjustment in focal length—the same projection distance can produce a different screen size, which is the direct reason for changing lenses; at the same time, full shift capability is retained, so the image can still be aligned after adjusting the focal length.

IV. Three Things to Confirm Before Replacement

• The panel must fall within the same group. We classify panels by group: DLP side—0.65″/0.66″/0.67″ in one group, 0.8″ in one group, 0.96″ in one group, 0.47″/0.48″ in one group; LCD side—0.59″/0.63″/0.64″ in one group, 0.76″/1.0″ in one group. This model belongs to the 0.47/0.48 group; projectors in the same group can be directly interchanged; cross-group installation will not fit, and forced installation will damage the DMD. For models with similar codes, it is still recommended to verify the nameplate.
• Interface and locking structure. Same-generation platforms generally have good interface compatibility, but locking clip positions differ between generations. If the image is skewed or edges are soft after installation, it is mostly due to the lock not being fully engaged, not a problem with the lens itself.
• Fixed focus has no zoom margin. Screen size can only be changed by moving the projector body; site dimensions must be measured accurately first, and an additional 10–20 cm should be allowed at the endpoints.

For models not on the list, it is safer to send us the projector nameplate and a photo of the original lens for verification—same-generation platforms often share interfaces, but ordering based on model similarity alone is not worth the risk.
