WD651 0.35:1 Projector Lens for 5 Hisense Models: PA92, HLP850, PA80, PA85, P75

WD651 is a short-throw lens for 0.65/0.66/0.67 panels (Hisense), with a 0.35:1 throw ratio. It is compatible with 5 models across 1 model series. This article 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 is a fixed-focus lens (0.35:1), so the installation distance varies linearly with image size, with no adjustment margin. Accurate measurements are essential before installation.

The values above are clear distances from the front of the lens to the projection screen and do not account for rear housing ventilation or cable-management space. They are calculated for a 16:10 image; actual values should be verified through on-site measurement and in the manual.

III. Compatible Models (5 Models, Hisense)

The table below is ordered from newest to oldest by model production date and includes the resolution, brightness, and original lens zoom ratio of each model, making it easy to identify the right option for your project.

The zoom ratio is the zoom factor of the original standard lens for the model (upper limit ÷ lower limit of the 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 5 models generally have throw ratios around 1.4-2.5:1. The 0.35:1 model featured here effectively adjusts the focal length, producing a different image size from the same projection distance—the direct reason for replacing the lens. It also retains full lens-shift capability, allowing the image to be realigned even after the focal length has been adjusted.

IV. Three Checks Before Replacement

• Panel size and resolution must match. This model is designed for 0.67-inch panels. Projectors with different panel sizes or resolutions may vary slightly in projection performance; checking the nameplate before installation is the safest option.
• Interface and locking mechanism. Interfaces are generally compatible within the same platform generation, but the locking tab positions vary between generations. If the image appears skewed or the edges look soft after installation, the lock is usually not fully engaged rather than the lens itself being faulty.
• A fixed-focus lens has no zoom adjustment. Image size can only be changed by moving the projector. The venue dimensions must be measured accurately, 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 projector nameplate and original lens for verification. Same-generation platforms often share interfaces, but ordering solely because the model numbers appear similar carries unnecessary risk.
