Vivitek LNS-5FX1 Short Fixed Lens for D5010-WNL D5110W-WNL D5190HD-WNL D5380U-WNL H5095

Vivitek OEM Lens LNS-5FX1 Short Fixed is an OEM optical accessory for Vivitek engineering projectors. It is a Short Throw lens with a 0.80:1 throw ratio for D/H Engineering and Cinema Series panels measured in inches. The OEM compatibility list covers 5 projector models; verify the projector model and panel size before installation, with no need for adapter rings. The value of an OEM lens lies not in the extra figures on a specification sheet, but in its factory calibration to the optical path and lens mount of that projector series: once installed, the image circle, edge illumination, and focus travel all match the design values, without having to rely on keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are based on the OEM specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications table, please contact us with the projector model. Ordering solely based on a similar model carries the risk that the lens will not fit.

2. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens has a fixed focal length (0.80:1), so the installation distance varies linearly with image size and offers no adjustment range. Accurate measurements are essential before installation.

These figures represent the clear distance from the front of the lens to the screen and do not include clearance behind the projector for ventilation and cabling. The calculations use a 16:10 aspect ratio; actual distances should be confirmed through on-site measurements and the OEM manual.

3. Compatible Projector Models (5 Models)

The following table is taken from the OEM model compatibility list. Brightness and resolution are populated from the model database; where data is unavailable, an em dash (—) is shown, and no assumptions are made.

To check whether a projector model not on the list is compatible, please send us photos of the projector nameplate and the existing lens. Same-generation platforms often share the same mount, but the risk of ordering based on a similar model is not worth taking.

Throw Ratios by Projector Series

The nominal throw ratio differs when the same LNS-5FX1 Short Fixed is used with the projector series listed below. Select the value according to the series of the actual projector.

4. Three Checks Before Replacement

• Panel size must match. LNS-5FX1 Short Fixed is designed for D/H Engineering and Cinema Series panels measured in inches. Even if the lens fits the mount, projectors with different panel sizes or resolutions may experience problems with image circle coverage and edge illumination.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.80:1. Use the table in Section 2 to calculate the required distance for your installation site. As a fixed-focus lens, it offers no adjustment range; even with a zoom lens, allow 10–20 cm of adjustment margin at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of that projector series. After installation, you must hear it click into place. A skewed image or soft edges are usually caused by incomplete locking, rather than a problem with the lens itself.

If you are uncertain, photograph the projector nameplate and the existing lens nameplate and send the photos to us. Comparing the actual items is the most reliable way to verify compatibility.
