WF200 Projector Lens 0.5:1 for Fujitsu IN1048SL IN1049SL INL4129 INL4128 and 2 Other Models

WF200 is a short-throw lens for the 0.65/0.66/0.67-inch panel group (Fujitsu), with a 0.5:1 throw ratio. It is compatible with 4 projector models across 1 model series. This article consolidates the lens specifications, installation distance, model compatibility list, and replacement considerations.

I. Lens Specifications

II. Converting Throw Ratio into Installation Distance

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 changes linearly with image size, with no room for adjustment. Accurate measurements are essential before installation.

These figures represent the clear distance from the front of the lens to the screen and do not allow for cooling clearance or cable-routing space behind the chassis. They are calculated for a 16:10 image format; actual on-site measurements and the manual take precedence.

III. Compatible Models (4 Models, Fujitsu)

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

The zoom ratio is the zoom factor of the model's factory-installed standard lens (upper limit ÷ lower limit of the factory lens's 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 the 4 models mostly have throw ratios in the 1.4-2.24:1 range. The 0.5:1 model featured here provides a different focal length, enabling the same projection distance to produce different image sizes—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 is changed.

IV. Three Checks Before Replacement

• Panel size and resolution must match.This model is designed for a 0.65-inch panel. Projection performance varies slightly among projectors with different panel sizes or resolutions, so checking the nameplate on the chassis before installation is the safest approach.
• Interfaces and locking mechanism.Interfaces are generally compatible within the same platform generation, but the locking latch position differs between generations. If the image appears skewed or the edges are not sharp after installation, the lock is usually not fully engaged; this is not a problem with the lens itself.
• A fixed-focus lens has no zoom adjustment.Image size can only be changed by moving the projector, so the site dimensions must be measured accurately in advance, with an additional 10–20 cm allowed at each endpoint.

For models not included in the list, the safest approach is to send us photos of the chassis nameplate and original lens for verification. Platforms of the same generation often share interfaces, but ordering solely on the basis of a similar model designation is not worth the risk.
