Eiki AH-AV24010 Zoom Long-Throw Projector Lens: PRO V1700 and PRO V2000 Compatibility

Eiki Original Lens AH-AV24010 Zoom is an original optical accessory for Eiki professional projectors, featuring a long throw (Long Throw) with a 1.98-3.95:1 throw ratio. The factory compatibility list covers 2 models. Before installation, simply verify the projector model and panel size—no adapter rings needed. The value of an original lens lies not in extra rows of specifications, but in the fact that it is factory-calibrated to the optical path and lens mount of the corresponding projector series. Once installed, the image circle, edge illumination, and focus travel all meet the design values, eliminating the need to compensate for image quality with keystone correction.

I. Lens Specifications

The above specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and lens mount type not listed in the specifications table, please contact us with the projector model. Placing an order based solely on a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This original zoom lens (1.98-3.95:1) covers a range of distances for a given image size and can focus anywhere within that range when properly installed.

These figures represent the clear distance from the front of the lens to the screen and do not account for clearance behind the projector for ventilation and cabling. Calculated for a 16:10 image; actual distances should be verified on site and according to the manufacturer's manual.

Image quality varies between the two ends of the zoom range: toward the short-throw end, the image is brighter and the edges appear slightly softer; toward the long-throw end, the edges are sharper and brightness decreases slightly. Where venue conditions allow, use the middle of the range. After installation, first find the sharpest position on the focus ring, then fine-tune the lens shift.

III. Compatible Models (2 Models)

The following table is taken from the manufacturer's compatibility list. Brightness and resolution have been populated from the model database; where the data is unavailable, they are shown as “—” and have not been estimated.

To confirm whether a model outside this list can be used, send us photographs of the projector nameplate and the existing lens. Projectors based on the same platform generation often share the same lens mount, but the risk of ordering based on a similar model is not worth taking.

Throw Ratios by Model Series

The nominal throw ratio varies by series when the same AH-AV24010 Zoom is installed. Select the value based on the series of the actual projector.

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution.Each original lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first.This lens has a rated throw ratio of 1.98-3.95:1. Use the table in Section II to calculate the distance based on your venue dimensions. Fixed-focus lenses offer no adjustment range, while zoom lenses still require an additional 10–20 cm at both ends.
• Verify the lens mount and locking mechanism.The original lens is calibrated to the lens mount of the corresponding projector series and must audibly lock into place after installation. A skewed image or soft edges usually indicate that the lens is not fully locked rather than a lens defect.

If you are unsure, send us one photograph of the projector nameplate and one of the existing lens nameplate. Verification against the actual hardware is the most reliable approach.
