NEC NP47ZL Zoom Standard Throw Projector Lens: PX2000UL PX2201UL Compatibility

NEC Original Lens NP47ZL Zoom is a genuine optical accessory for NEC installation projectors, belonging to the standard throw range with a throw ratio of 1.50-2.00:1. The original compatibility list covers 2 projector models; before installation, simply verify against the projector model and panel size—no adapter rings needed. The value of an original lens isn't about extra rows of numbers in the spec sheet, but that it is calibrated at the factory to the optical path and mount of that series' chassis: once installed, the image circle, edge illumination, and focus travel all match design values, so you don't need keystone correction to compensate for image quality.

1. Lens Specifications

Brand	NEC (NEC)
Lens Model	NP47ZL Zoom
Throw Ratio	1.50-2.00:1
Product Type	Standard Throw
Compatible Models	2 units
Warranty	12 months; after-sales service available for non-human damage, based on the date on the shipping document

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and mount type not shown in the spec table, please verify with us based on your projector model—ordering based on similar model numbers carries the risk of incompatibility.

2. Converting Throw Ratio to Installation Distance

Throw ratio is the ratio of installation distance to image width. This original lens is a zoom lens (1.50-2.00:1), so the same image size corresponds to a range of distances; as long as installation falls within this range, focus can be achieved.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 3.22 – 4.30 m
120 inches	2.58 m	Approx. 3.87 – 5.16 m
150 inches	3.22 m	Approx. 4.84 – 6.45 m
200 inches	4.30 m	Approx. 6.45 – 8.60 m

The above figures are the clear distance from the lens front to the screen, excluding rear ventilation and cabling space behind the projector. Calculated for 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the near end the image is brighter with slightly softer edges; toward the far end the edges are sharper with slightly reduced brightness. Where space permits, it is recommended to land in the middle of the range; after installation, first find the sharpest position on the focus ring, then fine-tune the shift.

3. Compatible Models (2 units)

The table below is taken from the original compatibility list; brightness and resolution are filled in from the model database, with "—" where unavailable—no speculation.

Model	Brightness	Resolution
PX2000UL	19000 lumens	1920x1200
PX2201UL	20500 lumens	1920x1200

To check whether models outside the list are compatible, please send us photos of the projector nameplate and the existing lens for verification—same-generation platforms often share mounts, but ordering based on similar model numbers is a risk not worth taking.

Throw Ratios Across Different Model Series

The same NP47ZL Zoom mounted on the following series has different nominal throw ratios; selection should be based on the actual series of your projector.

Model Series	Throw Ratio
—	1.50-2.00:1

4. Three Things to Confirm Before Replacement

• Confirm the projector chip and resolution. Original lenses are designed for specific panel sizes; with a different panel specification, 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 1.50-2.00:1; use the table in Section 2 to match your venue dimensions. Fixed-focus lenses have no margin, and even with zoom you should allow 10–20 cm at both ends.
• Verify the mount and locking. Original lenses are calibrated to the mount of that series' chassis; after installation you must hear the lock engage. Image skew and soft edges are mostly due to incomplete locking, not a problem with the lens itself.

If unsure, take a photo of the projector nameplate and the existing lens nameplate and send them to us—verifying against the actual hardware is the safest approach.
