Vivitek D88-ST001 Standard Zoom Long-Throw Projector Lens: Compatible with 19 Models Including

Vivitek Original Lens D88-ST001 Standard Zoom is a genuine optical accessory for Vivitek engineering projectors. It is a long-throw lens with a throw ratio of 1.73-2.27:1, designed for DU/DW/DX engineering series panels. The original compatibility list covers 19 models; before installation, simply verify against the projector model and panel size — no adapter rings needed. The value of an original lens isn't in extra rows of specs, but in being factory-calibrated to the optical path and bayonet of that series: once mounted, the image circle, edge illumination, and focus travel are all at design values, so you don't need keystone correction to compensate for image quality.

1. Lens Specifications

Brand	Vivitek
Lens Model	D88-ST001 Standard Zoom
Throw Ratio	1.73-2.27:1
Product Type	Long Throw
Compatible Panel	DU/DW/DX engineering series inch
Covered Models	19
Warranty	12 months; non-human damage eligible for after-sales service, based on the date on the shipping document

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and bayonet type not shown in the spec table, please verify with us against your projector model — ordering based on model similarity alone carries the risk of incompatibility.

2. Throw Ratio Conversion to Installation Distance

Throw ratio is the ratio of installation distance to screen width. This original lens is a zoom lens (1.73-2.27:1), so the same screen size corresponds to a range of distances; installation anywhere within this range will achieve focus.

Screen Size	Screen Width	Required Installation Distance
100 inches	2.15 m	Approx. 3.72 – 4.88 m
120 inches	2.58 m	Approx. 4.46 – 5.86 m
150 inches	3.22 m	Approx. 5.58 – 7.32 m
200 inches	4.30 m	Approx. 7.44 – 9.76 m

The above figures are the net distance from the lens face to the screen, excluding rear ventilation and cabling space. Calculated for 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the near end the image is brighter with slightly softer edges; toward the far end the edges are sharper with slightly reduced brightness. Where space permits, we recommend positioning in the middle of the range; after installation, first find the sharpest point on the focus ring, then fine-tune the shift.

For models not on the list, please send us photos of the projector nameplate and the existing lens for verification — same-generation platforms often share bayonets, but ordering based on model similarity is a risk not worth taking.

Throw Ratios Across Model Series

The same D88-ST001 Standard Zoom mounted on the following series has different nominal throw ratios; selection should be based on the actual series of your projector.

Model Series	Throw Ratio
—	1.73-2.27:1

4. Three Things to Confirm Before Replacement

• Panel size must match. The D88-ST001 Standard Zoom is designed for DU/DW/DX engineering series inch panels. For projectors with different panel sizes or resolutions, even if the bayonet fits, the image circle and edge illumination will be problematic.
• Calculate installation distance first. This lens has a nominal throw ratio of 1.73-2.27:1; apply it to your venue dimensions using the table in Section 2. Prime lenses have no margin; for zoom lenses, allow 10–20 cm at both ends.
• Verify bayonet and locking. The original lens is calibrated to the bayonet of that series; after mounting, you must hear it lock into place. Image skew or soft edges are usually due to incomplete locking, not the lens itself.

If unsure, take a photo of the projector nameplate and the existing lens nameplate and send them to us — verification against the actual hardware is the safest approach.
