WB110 Projector Lens 0.74–0.77:1 for Appotronics AL-FU715, FU10K, FU805, FU705, FU905

The WB110 is a short-throw lens for the 0.65/0.66/0.67 panel group (Appotronics), with a 0.74–0.77:1 throw ratio and lens shift. It is compatible with 5 models from 1 model series. This guide consolidates the lens specifications, installation distances, model compatibility list, and replacement considerations.

1. Lens Specifications

Lens shift is the key differentiator for this lens. The 70.30% horizontal and 32% vertical shift ranges allow the projector to be installed away from the screen’s center axis and the image repositioned through lens shift without relying on keystone correction. Keystone correction comes at a cost—each correction step reduces the effective pixel count and blurs text edges. In professional installations, never resort to keystone correction when lens shift can resolve the issue; this is the minimum standard for image quality.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This lens has a zoom range of 0.74–0.77:1, so each image size corresponds to a range of installation distances, and the lens can focus at any point within that range.

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

Image quality differs at the two ends of the zoom range: the image is brighter with slightly softer edges near the close end, while the edges are sharper and brightness is slightly lower near the far end. Where site conditions allow, the middle of the range is recommended. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift—accurate alignment is difficult when both variables are adjusted together.

3. Compatible Models (5 Models, Appotronics)

The table below is arranged by model production date from newest to oldest and includes each model’s resolution, brightness, and factory-lens zoom ratio, making it easy to identify the right option for project requirements.

Common Features of These Models

The standard factory lenses for these 5 models mostly have throw ratios listed as Depends on the lens. The 0.74–0.77:1 model featured here has a different focal-length range, allowing different image sizes at 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 zoom range.

4. Three Checks Before Replacement

• The panel and resolution must match. This model is compatible with a 0.67-inch panel. Projectors with a different panel size or resolution may vary in projection performance; checking the chassis nameplate before installation is the safest approach.
• Check the interface and locking mechanism. Interfaces are generally compatible within the same platform generation, but the locking latch position differs by generation. If the image is skewed or the edges appear soft after installation, the lock is usually not fully engaged rather than the lens itself being faulty.
• Include lens-shift margin in the installation plan. The shift range provides installation flexibility, but edge image quality declines at the limits. Keep actual shifts within 70% of the rated values.

For models not on the list, the safest approach is to send us the chassis nameplate and a photo of the original lens for verification—platforms of the same generation often share interfaces, but the risks of ordering based only on similar model numbers are not worth taking.
