Sharp XP-52ZL Short Zoom Standard Throw Lens Guide

Sharp OEM Lens XP-52ZL Short Zoom is an OEM optical accessory for Sharp engineering projectors, featuring a standard throw ratio of 0.65-0.87:1. The OEM compatibility list covers 5 models; before installation, simply verify the projector model and panel size, with no need for adapter-ring workarounds. The value of an OEM lens lies not in the extra figures in its specifications, but in the fact that it is factory-calibrated to the optical path and mount of that projector series: once fitted, the image circle, edge illumination, and focusing travel all operate at their design values, so there is no need to use keystone correction to compensate for image quality.

I. Lens Specifications

Brand	Sharp (Sharp)
Lens Model	XP-52ZL Short Zoom
Throw Ratio	0.65-0.87:1
Product Type	Standard throw (Standard Throw)
Compatible Models	5 models
Warranty	12 months; if the damage was not caused by the user, after-sales service is available, subject to the date shown on the shipping invoice

The above specifications are subject to the OEM specifications. Any mechanical dimensions, flange distances, and mount types not shown in the specifications table should be verified with us using the projector model; ordering based solely on a similar model carries the risk of incompatibility.

II. Converting Throw Ratio to Installation Distance

Throw ratio is the ratio of installation distance to image width. This OEM lens has a zoom range of 0.65-0.87:1, so a given image size corresponds to a range of installation distances; any position within that range can be brought into focus.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	approx. 1.40 – 1.87 m
120 inches	2.58 m	approx. 1.68 – 2.24 m
150 inches	3.22 m	approx. 2.10 – 2.81 m
200 inches	4.30 m	approx. 2.79 – 3.74 m

These distances are the clear distance from the front surface of the lens to the screen and do not allow for cooling clearance and cabling space at the rear of the projector. The figures are calculated for a 16:10 image; actual distances should be verified on site and in accordance with the OEM manual.

Image quality varies at the two ends of the zoom range: at the short end, the image is brighter and the edges are slightly softer; at the long end, the edges are sharper and brightness decreases slightly. Where the venue allows, use a position near the middle of the range. After installation, turn the focus ring to find the sharpest image, then fine-tune the lens shift.

III. Compatible Models (5 Models)

The table below is taken from the OEM compatibility list. Brightness and resolution are sourced from the model database; entries marked — could not be verified and have not been inferred.

Model	Brightness	Resolution
XP-A155U-B	14000 lumens	1920x1200
XP-A155U-W	14000 lumens	1920x1200
XP-A175U-B	16000 lumens	1920x1200
XP-A175U-W	16000 lumens	1920x1200
XP-A201U-B	20000 lumens	1920x1200

For a model not on the list, send us photos of the projector nameplate and current lens for verification—same-generation platforms often share the same mount, but ordering based on a similar model carries an avoidable risk.

Throw Ratio by Model Series

The nominal throw ratio varies by series when the same XP-52ZL Short Zoom is installed on the following series. Select the value based on the series of the projector in use.

Model Series	Throw Ratio
—	0.65-0.87:1

IV. Three Checks Before Replacement

• Confirm the projector panel and resolution. OEM lenses are designed for a specific panel size. If the panel specification differs, the image circle cannot cover it, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.65-0.87:1. Use the table in Section II to match the dimensions of your installation site. A fixed-focus lens offers no margin, and even a zoom lens requires 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of that projector series. After installation, you must hear the lock engage. A skewed image or soft edges are usually caused by an incompletely engaged lock, not by a fault in the lens.

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