Vivitek D88-WZ01 Short Zoom Lens Fits 19 Models: D8010W D8900 DH6671 DH6861 DK10000Z DK8500Z-BK

Vivitek OEM Lens D88-WZ01 Short Zoom is an original optical accessory for Vivitek engineering projectors. It belongs to the Standard Throw category, has a throw ratio of 1.25-1.79:1, and matches the DU/DW/DX engineering-series inch panels. The OEM compatibility list covers 19 models, so before installation you only need to verify the chassis model and panel size — there is no need to make do with adapter rings. The value of an OEM lens lies not in the extra rows of figures on the spec sheet, but in the fact that it is calibrated at the factory to the optical path and mount of that chassis series: once fitted, the image circle, edge illumination, and focus travel are all design values, so there is no need to compensate for image quality with keystone correction.

I. Lens Specifications

The above specifications are subject to the manufacturer's official specs. For mechanical dimensions, flange distance, and mount type that are not listed here, please check with us based on the chassis model — ordering directly based on a similar model number carries the risk of the lens not fitting.

II. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (1.25-1.79:1), so a single image size corresponds to a range of distances, and any position within that range can be focused.

The above is the net distance from the front element of the lens to the screen, excluding the space required for rear cooling and cabling. Figures are calculated for a 16:10 aspect ratio; in practice, on-site measurement and the manufacturer's manual prevail.

Image quality differs at the two ends of the zoom range: near the close end the image is brighter and the edges are slightly soft; near the long end the edges are sharper and brightness drops slightly. Where the venue allows, aim for the middle of the range, and after installation first find the sharpest position on the focus ring, then fine-tune the lens shift.

III. Compatible Models (19 units)

The table below is taken from the manufacturer's compatibility list; brightness and resolution are filled in from the model database, and entries that cannot be retrieved are shown as "—" — no estimates are made.

To check whether a model outside the list can be used, send us a photo of the nameplate on the chassis and a photo of the existing lens — platforms of the same generation often share the same mount, but ordering on the basis of a similar model number is not worth the risk.

Throw Ratio by Model Series

The same D88-WZ01 Short Zoom has different nominal throw ratios across the series listed below, so take the value from the series that your actual chassis belongs to.

IV. Three Checks Before Replacement

• Make sure the panel size matches. D88-WZ01 Short Zoom is designed for DU/DW/DX engineering-series inch panels. On machines with a different panel size or a different resolution, the image circle and edge illumination will be off even if the mount fits.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.25-1.79:1; apply the table in Section II to your own venue dimensions. A fixed-focus lens offers no margin, and even a zoom lens needs 10–20 cm of allowance at both ends.
• Check the mount and the locking mechanism. The OEM lens is calibrated to the mount of that chassis series, and after installation you must hear it click into the locked position; a skewed image and soft edges are usually caused by an incompletely locked lens, not by a problem with the lens itself.

If you are unsure, take one photo of the chassis nameplate and one photo of the existing lens nameplate and send them to us — checking against the actual hardware is the safest approach.
