D89-SMLZ01 2.1-4:1 Long Throw Zoom Lens for DU8000 Series Projectors

The Vivitek D89-SMLZ01 is a long-throw zoom lens identified for DU8000 Series projectors. Its stated 2.1-4:1 throw-ratio range supports layouts where the projector must be positioned farther from the image surface than a standard or short-throw configuration would allow. This lens is intended as a specific installation component rather than a complete projector, so projector compatibility, image width, and available throw distance should be verified before purchase.

Ideal Use Cases

The D89-SMLZ01 is suited to planned projection systems in which room geometry, mounting infrastructure, or audience placement requires substantial distance between the projector and screen. Potential applications include installations where the projector needs to remain behind the primary seating or activity area, as well as projects that must work around fixed ceiling positions, structural features, equipment platforms, or dedicated projection locations.

The 2.1-4:1 throw ratio provides a defined planning range for matching projector position to image width. This makes the lens relevant when an installer needs more placement latitude than a single fixed throw ratio can provide. It may also be useful when replacing or updating a DU8000 Series installation while retaining an established long-throw mounting location.

Why Choose This Model

The primary reason to select this model is its stated combination of DU8000 Series compatibility, long-throw operation, and zoom capability. The D89-SMLZ01 designation gives buyers and integrators a specific model reference for procurement, while SKU SS-5811141776-VV provides an additional identifier for order verification.

Choosing a projector lens by exact model is important because lens selection affects whether the intended image size can be produced from the available mounting position. This model should be considered when the required installation falls within its stated 2.1-4:1 throw-ratio range and the projector belongs to the specified DU8000 Series.

Installation and Integration

Before ordering, measure the planned distance from the lens position to the image surface and confirm the required image width. Throw ratio relates projection distance to image width, so both measurements are needed to determine whether the installation fits within the stated range. The zoom range can then be used to accommodate compatible positions between the near and far limits represented by the supplied ratio.

Installers should also verify the exact DU8000 Series projector model rather than relying on series naming alone. The provided data does not specify mounting procedures, lens-shift capability, focus controls, projection-size limits, or included accessories. Those requirements should be confirmed for the projector and installation before the lens is placed into service.

Performance Highlights

The performance information supplied for this listing centers on optical placement. The D89-SMLZ01 is identified as a long-throw zoom lens with a 2.1-4:1 throw ratio. This range allows the projector-to-screen relationship to be planned across multiple compatible distances instead of being restricted to one fixed position.

No brightness, contrast, resolution, color, focus, lens-shift, or light-source specifications are provided for the lens in the available product data. Those image-performance characteristics depend on confirmed specifications for the associated projector and projection system. The stated value of this model is therefore its long-throw optical format and its identified relationship to DU8000 Series projectors.

What Makes It Different

This is a purpose-identified projection lens, not a general-purpose accessory. Its model designation, specified projector series, and stated throw-ratio range allow it to be evaluated against an installation drawing or measured room. The broad ratio range indicated in the product title also distinguishes it from a fixed lens that supports only one projector placement relative to image width.

The available source data contains search-result images and limited product-specific technical information, so those images are not presented here as verified representations of the D89-SMLZ01. Buyers should use the model number, compatible series, throw ratio, and SKU as the principal references when confirming the item.

Final Assessment

The Vivitek D89-SMLZ01 is a focused choice for DU8000 Series projection installations requiring a long-throw zoom lens within the stated 2.1-4:1 throw-ratio range. It offers defined optical placement criteria for system planning without implying projector capabilities that are not supplied in the source data. Confirm the exact projector model, required image width, measured throw distance, and installation requirements before ordering.
