Ultra Short Throw Lens, DU8190Z, DU8090Z, DK8500Z, DK10000Z, DU8195Z

Ideal Use Cases

This Vivitek ultra short throw lens is identified for installations using the DU8190Z, DU8090Z, DK8500Z, DK10000Z or DU8195Z projector. Its ultra short throw designation makes it appropriate when the compatible projector must be positioned close to the intended image area instead of relying on a longer projection path. This is particularly relevant when placement depth is a primary design constraint. Image size and projection distance are not fixed in the supplied data, so both must be calculated for the selected lens and the specific installation.

Why Choose This Model

The principal advantage of this lens is its stated compatibility with five named Vivitek projector models. That model-level identification, together with SKU 3797866500-SVK, provides clear information for matching the lens to an existing projector or a planned system. The DU8190Z documentation describes an interchangeable-lens platform with eight optional lenses. Across that complete lens selection, documented throw ratios extend from 0.38:1 to 5.31-8.26:1. This range describes the DU8190Z lens family and is not an individual throw-ratio specification for this particular lens.

Choosing by exact projector designation and SKU is therefore essential. The supplied information does not state a focal length, aperture, individual numeric throw ratio or fixed image-size range for this lens.

Installation and Integration

The documented DU8190Z platform provides motorized focus and zoom as well as motorized lens shift. Its optical adjustment range is listed as vertical +64 percent to -33 percent and horizontal +24 percent to -14 percent, based on total image height. The projector also supports vertical keystone correction of plus or minus 40 degrees and horizontal correction of plus or minus 60 degrees. These adjustment specifications describe the DU8190Z host projector and should not be interpreted as independent mechanical specifications for the lens.

For physical planning around a DU8190Z installation, the projector measures 500 x 580 x 205 mm and weighs 28 kg. The lens-specific dimensions, weight and mounting procedure are not supplied. Confirm the exact projector model, required image geometry and available placement depth before completing the installation plan.

Performance Highlights

On the documented DU8190Z reference platform, the projection system delivers native WUXGA resolution of 1920 x 1200, maximum WUXGA output at 60 Hz, 10,000 ANSI lumens and a 10,000:1 contrast ratio. It uses single-chip Texas Instruments DLP technology with a 0.67-inch DMD and a laser light source rated for up to 20,000 hours. The native aspect ratio is 16:10.

Those values establish the performance context of one compatible projector; they are not standalone performance ratings created by the lens. The final image size and projection distance remain dependent on the selected lens, while brightness, resolution, contrast and video compatibility are determined by the host projector.

What Makes It Different

This product combines an ultra short throw lens format with a clearly stated compatibility list covering the DU8190Z, DU8090Z, DK8500Z, DK10000Z and DU8195Z. That breadth makes the precise product identity more useful than selecting a lens from appearance alone. The listing also distinguishes this lens from the broader range of eight optional DU8190Z lenses, whose collective throw-ratio coverage includes both ultra-short and substantially longer-throw configurations.

No lens-specific warranty, UPC, EAN, optical memory specification, lens dimensions or included accessories are provided. The five-year projector and laser-light-source warranty described in the DU8190Z material applies to the projector documentation and is not presented here as a warranty for this lens.

Final Assessment

The Vivitek ultra short throw lens, SKU 3797866500-SVK, is a focused option for installations built around one of the five projector models named in the product data. Its strongest purchasing identifiers are the ultra short throw classification, exact compatibility list and SKU. For a dependable fit, verify the projector model and calculate the required image geometry before ordering, since the supplied information does not provide this lens’s individual throw ratio, image-size range or projection-distance table.
