WK093 Projector Lens 0.413:1 for 4 Aurora Models: OR-K1030QZ, K1110QZ, K1010UZ, K880UZ

WK093 is a short-throw lens for 0.76-inch panels (Aurora), with a 0.413:1 throw ratio and lens shift. It supports 4 compatible projector models across 1 model series. This article consolidates the lens specifications, installation distance, model compatibility list, and replacement key points.

1. Lens Specifications

Lens-shift capability is the key differentiator of this lens. Its shift range of 47.5% horizontal and 20.8% vertical allows the projector to be installed off the screen centerline, with lens shift bringing the image back into alignment without keystone correction. Keystone correction has a cost—each adjustment step reduces the effective pixel count and can blur text edges. In professional installations, never use keystone correction when lens shift can resolve the issue; this is the baseline for image quality.

2. Installation Distance Based on Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This is a fixed-focus lens (0.413:1), so the installation distance changes linearly with image size and offers no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front lens surface to the screen and do not include clearance for rear housing cooling and cable connections. Calculations are based on a 16:10 image; actual values should be verified through on-site measurements and the manual.

3. Compatible Models (4 Models, Aurora)

The table below is ordered by model production date, from newest to oldest, and lists each model's resolution, brightness, and zoom ratio for the factory-standard lens, making it easy to identify the right option for a project.

The zoom ratio is the zoom factor of the model's factory-standard lens (upper ÷ lower limits of its factory 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 4 models mostly have throw ratios within 1.42-2.64:1. The 0.413:1 model featured in this article effectively changes the focal length, allowing the same projection distance to produce a different image size—this is the direct reason for replacing the lens. It also retains full lens-shift capability, so the image can still be aligned after the focal-length adjustment.

4. Three Checks Before Replacement

• Panel and resolution must match. This model is compatible with 0.76-inch panels. Projectors with different panel sizes or resolutions can produce different projection performance, so the safest approach is to verify the specifications against the nameplate on the projector before installation.
• Interface and locking mechanism. Interfaces are generally compatible across platforms of the same generation, but the position of the locking latch can differ by generation. If the image appears skewed or the edges do not look sharp after installation, the lock is usually not fully engaged rather than the lens being at fault.
• Include the shift margin in the installation plan. The shift range provides some installation flexibility, but edge image quality declines when the shift is pushed to its limits. We recommend keeping actual shift within 70% of the rated values.

For a model not on the list, the safest course is to send us the projector nameplate and a photo of the original lens for verification. Same-generation platforms often share the same interfaces, but the risks of ordering based solely on a similar model designation are not worth taking.
