NEC NP49ZL Zoom Long-Throw Lens for PX2000UL/PX2000UL-47ZL/PX2201UL/PX2201UL-48ZL

NEC Genuine Lens NP49ZL Zoom is an OEM optical accessory for NEC business projectors. It is a long-throw lens (Long Throw) with a throw ratio of 4.00-7.00:1. The OEM compatibility list covers 4 models. Verify the projector model and panel size before installation; no adapter-ring workaround is needed. The value of an OEM lens lies not in the additional figures in its specifications, but in its factory calibration to the optical path and lens mount of the corresponding projector series. Once installed, the image circle, edge illumination, and focusing travel are all delivered at their design values, eliminating the need for keystone correction to compensate for image quality.

I. Lens Specifications

Brand	NEC (NEC)
Lens Model	NP49ZL Zoom
Throw Ratio	4.00-7.00:1
Product Type	Long Throw
Compatible Models	4 models
Warranty	12 months; after-sales service is available for damage not caused by the user, subject to the date on the shipping receipt

The above specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and lens-mount type not shown in the specifications table, please check your projector model with us. Ordering solely because the model numbers appear similar may result in an incompatible fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This genuine zoom lens (4.00-7.00:1) covers a range of installation distances for any given image size and can focus at any point within that range.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 8.60 – 15.05 m
120 inches	2.58 m	Approx. 10.32 – 18.06 m
150 inches	3.22 m	Approx. 12.90 – 22.57 m
200 inches	4.30 m	Approx. 17.20 – 30.10 m

These figures represent the clear distance from the front of the lens to the screen and do not include space required for cooling and cable connections at the rear of the projector. They are calculated for a 16:10 image; actual on-site measurements and the manufacturer's manual take precedence.

Image performance differs at both ends of the zoom range: the image is brighter with slightly softer edges toward the near end, while the edges are sharper with slightly reduced brightness toward the far end. Where the venue permits, use the middle of the range. After installation, find the sharpest position on the focus ring, then fine-tune the lens shift.

III. Compatible Models (4 Units)

The following table is taken from the OEM compatibility list. Brightness and resolution values are taken from the model database; unavailable values are shown as “—” and are not estimated.

Model	Brightness	Resolution
PX2000UL	19000 lumens	1920x1200
PX2000UL-47ZL	19000 lumens	1920x1200
PX2201UL	20500 lumens	1920x1200
PX2201UL-48ZL	20500 lumens	1920x1200

To determine whether a model not listed here is compatible, send us photos of the projector nameplate and the existing lens. Projectors based on the same-generation platform often share the same lens mount, but ordering based solely on a similar model name introduces unnecessary risk.

Throw Ratio by Model Series

The nominal throw ratio of the same NP49ZL Zoom lens varies across the series listed below. Select the value based on the series of the projector in use.

Model Series	Throw Ratio
—	4.00-7.00:1

IV. Three Checks Before Replacement

• Confirm the projector panel and resolution.OEM lenses are 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 nominal throw ratio of 4.00-7.00:1. Use the table in Section II to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, and even a zoom lens should have 10–20 cm of extra room at both ends.
• Verify the lens mount and locking mechanism.This OEM lens is calibrated for the lens mount used on the corresponding projector series. You must hear it click into the locked position after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a fault in the lens.

If you are unsure, send us one photo of the projector nameplate and one of the nameplate on the existing lens. Verification against the actual items is the safest approach.
