Semi Short Zoom 21.25-1.6:1

The Vivitek Semi Short Zoom 2 is a projection zoom lens identified by SKU SS-5811131167-VV. Its defining published specification is a 1.25-1.6:1 throw-ratio range, placing it in the semi-short category. Throw ratio describes the relationship between projection distance and image width. At the 1.25 end of the range, the required distance is approximately 1.25 times the image width; at the 1.6 end, it is approximately 1.6 times the image width. This gives system designers a concrete range for evaluating room geometry before selecting the lens.

Ideal Use Cases

This model should be considered for projection layouts whose calculated throw ratio falls between 1.25:1 and 1.6:1. That can include new installations, projector repositioning projects, or replacement work where the available distance and desired image width are already known. The ratio is the key selection criterion: divide the planned lens-to-screen distance by the desired image width and compare the result with the stated range. A result inside the range indicates that the placement geometry may be suitable, subject to projector and lens-mount compatibility.

Why Choose This Model

The principal reason to select the Semi Short Zoom 2 is its clearly defined variable throw range. Rather than limiting an installation to one fixed ratio, the 1.25-1.6:1 specification provides a 0.35 span for aligning projector placement with the required image width. This can be useful when a planned location offers some adjustment space or when the final image dimensions need to be coordinated with an established mounting position. SKU SS-5811131167-VV distinguishes this specific Vivitek configuration for ordering and project documentation.

Installation and Integration

Begin installation planning with accurate measurements of the intended image width and the distance from the projection lens to the screen. The required throw ratio is calculated by dividing that distance by the image width. Confirm that the result remains within 1.25-1.6:1 across the intended setup. The available source data does not provide compatible projector models, projection-size limits, mounting instructions, lens-shift ranges, focus controls, dimensions, or weight. Those details should therefore be verified for the exact projector before purchase or installation.

Compatibility is especially important because a suitable throw ratio does not by itself confirm that a lens will attach to or operate with a particular projector. Check the projector model, supported lens system, physical clearance, mounting location, and any required installation accessories. Integrators should also confirm how the projector manufacturer measures throw distance, particularly when comparing existing site measurements with design calculations.

Performance Highlights

The documented performance highlight is the 1.25-1.6:1 throw-ratio range. It establishes the placement envelope that this zoom configuration is designed to address and allows direct comparison with a room’s calculated requirement. No brightness, contrast, resolution, color, uniformity, lens-shift, or focus specifications were supplied. Those image-performance characteristics cannot be stated for this listing and may also depend on the projector used with the lens.

What Makes It Different

This model is differentiated by its semi-short zoom classification, its specific 1.25-1.6:1 ratio range, and its Vivitek product identity. The specification sits between a single-ratio lens and an unspecified general-purpose zoom option by giving buyers a defined placement range to evaluate. The listing avoids assigning unsupported projector capabilities to the lens: no claims are made regarding resolution, light output, refresh rate, connectivity, audio, or image processing because those details are not present in the supplied product information.

Final Assessment

The Vivitek Semi Short Zoom 2 is a focused installation component for projects requiring a throw ratio from 1.25:1 through 1.6:1. Its suitability depends on two essential checks: the planned distance-to-image-width calculation and confirmed compatibility with the intended projector. When both conditions are satisfied, SKU SS-5811131167-VV provides the precise reference needed for procurement. Buyers should obtain projector-specific compatibility and mechanical specifications before finalizing an order.
