0.90-1.2:1 Short-Throw Zoom Lens for DU9900Z/DU9800Z Projectors

Ideal Use Cases

The Vivitek 0.90-1.2:1 Short-Throw Zoom Lens is intended for projection installations built around a DU9900Z or DU9800Z projector and requiring the stated throw-ratio window. It is most relevant when the planned projector position, image width, and room layout have already been evaluated and a lens within this range has been identified. Because the listing specifies a range rather than one fixed ratio, this model provides zoom capability between the two stated limits. Selection should begin by confirming both the projector model and the required throw ratio against the project plan.

Why Choose This Model

This product has a clearly defined role: it is a short-throw zoom lens specified for two named Vivitek projector models, rather than a complete projector or general-purpose accessory. Its 0.90-1.2:1 throw ratio is the principal optical selection detail supplied for the lens, while SKU SS-3796100207-VV provides exact catalog identification. For additional context, the DU9800Z source material describes that projector platform as supporting five motorised interchangeable lenses spanning an overall range from 0.84:1 to 7.00:1. The ratio stated for this lens falls within that broader installation range.

Installation and Integration

Before ordering, confirm that the installation uses a DU9900Z or DU9800Z and calls for a throw ratio between 0.90:1 and 1.2:1. The supplied data does not state a zoom factor, focus method, lens-shift range, projection-size range, physical dimensions, weight, mounting procedure, or included accessories. Those details should not be inferred from specifications for the compatible projector. The data also does not explicitly identify this individual lens as motorised, even though the DU9800Z source describes its broader interchangeable-lens range as motorised. Final placement and integration should therefore be checked against the requirements and documentation available for the specific projector installation.

Performance Highlights

The supplied performance information primarily describes the compatible DU9800Z projector. That model is identified as a single-chip laser projector delivering 18,000 ANSI lumens, with WUXGA resolution, a stated 10,000:1 contrast ratio, and a stated laser life of 20,000 hours. These are projector-level specifications and should not be interpreted as independent specifications for the lens. For this product, the documented performance details are its short-throw classification, zoom-lens design, and 0.90-1.2:1 throw-ratio range.

What Makes It Different

The lens is distinguished by the combination of a defined short-throw range and stated compatibility with both the DU9900Z and DU9800Z. This makes the listing easy to evaluate using two concrete criteria: projector model and required throw ratio. Compatibility with both projectors is identified in the supplied product title, while the linked manufacturer material specifically provides installation and performance context for the DU9800Z. A separate lens datasheet was not supplied, so unspecified values such as optical construction, aperture, lens shift, focus controls, dimensions, and warranty have intentionally been left unstated.

Final Assessment

This Vivitek lens is a focused installation component for projects that match its documented 0.90-1.2:1 short-throw zoom range and use a DU9900Z or DU9800Z projector. Its strongest purchasing information is precise rather than extensive: a defined lens category, two compatible projector models, a stated throw-ratio range, and the catalog SKU SS-3796100207-VV. It should be selected when those details align with the installation design. Where a project depends on motorisation, exact lens shift, physical clearances, projection dimensions, or supplied accessories, confirm those currently unspecified details before purchase.
