Sharp XP-55ZL Zoom Long-Throw Lens for XP-A155U-B XP-A155U-W XP-A175U-B XP-A175U-W XP-A201U-B

Sharp Genuine Lens XP-55ZL Zoom is an original optical accessory for Sharp engineering projectors. It is a long-throw lens with a throw ratio of 1.98-3.95:1. The original compatibility list covers 5 models. Before installation, simply verify the projector model and panel size; no adapter ring is needed. The value of an original lens lies not in the additional figures on a specification sheet, but in its factory calibration for the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focus travel are all set to their design values, eliminating the need for keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and mount type not listed in the specifications, please contact us with the projector model. Placing an order directly based on a similar model carries the risk of the lens being incompatible.

2. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This genuine zoom lens has a throw ratio of 1.98-3.95:1, so each image size corresponds to a range of installation distances. The lens can be focused at any position within that range.

These figures represent the clear distance from the front of the lens to the screen and do not include space for rear housing ventilation and cable connections. Calculated for a 16:10 image, actual installation should be based on on-site measurements and the original manufacturer's manual.

Image performance varies at both ends of the zoom range: images are brighter with slightly softer edges near the shorter end, while the edges appear sharper with slightly reduced brightness near the longer end. Where space permits, use the middle of the range. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift.

3. Compatible Models (5 Models)

The following table is taken from the original compatibility list. Brightness and resolution have been populated from the model database; entries marked with an em dash indicate that the data is unavailable, and no assumptions have been made.

For models outside the compatibility list, please send us a photo of the projector nameplate and the existing lens for verification. Projectors from the same generation often share the same mount, but the risks of ordering based on a similar model outweigh the convenience.

Throw Ratio by Model Series

The rated throw ratio of the same XP-55ZL Zoom varies by projector series. When selecting a lens, use the value for the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector panel and resolution.Original lenses are designed for specific panel sizes. If the panel specifications differ, the image circle will not 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 2 and apply it to the dimensions of your installation site. A fixed-focus lens provides no adjustment margin, so even a zoom lens requires 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism.The original lens is calibrated for the mount of the corresponding projector series. After installation, you must hear the lock engage. A skewed image or soft edges are usually caused by an incompletely engaged lock rather than a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one photo of the existing lens nameplate and send them to us. Verification against the actual products is the most reliable approach.
