Vivitek D98-0810 Ultra Short Zoom lens, 0.84-1.03:1 standard throw, compatible with 1 projector model, including DU9000. Authorized supply for bulk orders.
Vivitek Original Lens D98-0810 Ultra Short Zoom is an original optical accessory for Vivitek engineering projectors. It is a Standard Throw lens with a 0.84-1.03:1 throw ratio and is designed for inch panels in the DU/DW/DX engineering series. The factory compatibility list covers one model. Before installation, simply verify the projector model and panel size—no adapter ring is needed. The value of an original lens lies not in the additional figures in its specifications, but in its factory calibration to the optical path and mount of the corresponding projector series. Once installed, image circle, edge illumination, and focusing travel are all at their design values, with no need to compensate for image quality using keystone correction.

Factory specifications take precedence. For mechanical dimensions, flange distance, and mount type not shown in the specifications table, please contact us with the projector model. Ordering solely because the model numbers appear similar carries a risk that the lens will not fit.
II. Converting Throw Ratio into Installation Distance
The throw ratio is the ratio of the installation distance to the image width. This original lens is a zoom lens (0.84-1.03:1), so a given image size corresponds to a range of installation distances. It can focus at any position within that range.
| Image Size | Image Width | Required Installation Distance |
|---|---|---|
| 100 inches | 2.15 m | Approximately 1.81 – 2.21 m |
| 120 inches | 2.58 m | Approximately 2.17 – 2.66 m |
| 150 inches | 3.22 m | Approximately 2.71 – 3.32 m |
| 200 inches | 4.30 m | Approximately 3.61 – 4.43 m |
These figures represent the clear distance from the front of the lens to the screen and do not include clearance for rear housing ventilation or cable connections. They are calculated for a 16:10 image; actual measurements and the factory manual take precedence.
Image quality varies at the two zoom extremes. Near the close end, the image is brighter and the edges are slightly softer; near the long end, the edges are sharper and brightness decreases slightly. When the venue allows, placing the lens in the middle of the range is recommended. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift.
III. Compatible Models (1 model)
The following table is taken from the factory compatibility list. Brightness and resolution are populated from the model database; unavailable information is marked as「—」without speculation.
| Model | Brightness | Resolution |
|---|---|---|
| DU9000 | 12000 lumens | 1920x1200 |
To determine whether a model not listed here is compatible, send us a photo of the projector nameplate and the existing lens for verification. Platforms of the same generation often share the same mount, but the risk of ordering based on a similar model designation is not worth taking.
Throw Ratios by Model Series
The rated throw ratio varies when the same D98-0810 Ultra Short Zoom is installed on the following series. Select the value based on the series of the actual projector.
| Model Series | Throw Ratio |
|---|---|
| — | 0.84-1.03:1 |
IV. Three Checks Before Replacement
- Verify the panel size. D98-0810 Ultra Short Zoom is designed for inch panels in the DU/DW/DX engineering series. Even if the lens fits the mount, projectors with a different panel size or resolution may experience problems with image circle and edge illumination.
- Calculate the installation distance first. This lens has a rated throw ratio of 0.84-1.03:1. Use the table in Section II to calculate the distance for your venue. Fixed-focus lenses provide no adjustment margin, and zoom lenses should also allow an additional 10–20 cm at both ends.
- Verify the mount and locking mechanism. The original lens is calibrated to the mount of the corresponding projector series. After installation, confirm that it is fully locked and clicks into position. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with the lens itself.
If you are unsure, send us one photo each of the projector nameplate and the existing lens nameplate. Verification against the actual hardware is the most reliable approach.
