Sharp NP18ZL – 1.73-2.27:1 Zoom Lens for PX Series Projectors

Product Overview

The Sharp NEC NP18ZL is a 1.73 to 2.27:1 standard-throw zoom projector lens with lens shift and lens memory, engineered for NEC PX Series installation projectors. It is one of six optional bayonet lenses that let AV integrators match throw distance to room geometry in conference rooms, auditoriums and exhibition spaces. For commercial projector lens replacement or new fixed-install projection systems, the NP18ZL covers mid-range throw distances with high optical quality.

Product Description

The NP18ZL standard-throw zoom lens is designed for the NEC NP-PX700W/PX750U/PX800X, NP-PX700W2/PX750U2/PX800X2, NP-PX803UL-BK/PX803UL-WH and NP-PX1004UL-BK/PX1004UL-WH large-venue projectors. Interchangeable lens systems are central to professional projector installation: rather than compromising on projector placement, integrators select the lens whose throw ratio fits the projection distance and screen size the room demands. With a 1.73 to 2.27:1 throw ratio and 1.3x zoom range, the NP18ZL suits mid-depth rooms such as boardrooms, lecture halls, houses of worship and staging environments where the projector sits well back from the screen.

The lens supports the projector's powered lens shift, allowing precise image positioning without physically moving a rack- or ceiling-mounted chassis, and the lens memory function stores zoom, focus and shift presets so different screen formats can be recalled instantly — useful in multi-purpose rooms that alternate between aspect ratios. A bright f/1.64 to f/1.86 aperture preserves light output across the zoom range, protecting the lumen performance of high-output PX Series laser and lamp projectors. Installation is tool-free: the bayonet mount lets end users or technicians swap lenses in the field in minutes, simplifying AV system integration, lens staging and rental workflows.

Key Features

Frequently Asked Questions

Which projectors is the NP18ZL compatible with?

The NP18ZL fits the NEC NP-PX700W, PX750U, PX800X, PX700W2, PX750U2, PX800X2, PX803UL-BK/WH and PX1004UL-BK/WH installation projectors. It is not the 4K variant; the NP-PX1005QL uses the separate NP18ZL-4K lens.

Do I need special tools to install this lens?

No. The bayonet-style mount is designed for tool-free installation, so a technician or end user can swap lenses in the field in a few minutes.

How do I know if this throw ratio fits my room?

Multiply your planned throw distance by the screen width: if the projector-to-screen distance divided by image width falls between 1.73 and 2.27, the NP18ZL is the correct lens. For shorter or longer rooms, other PX Series lenses cover adjacent ranges.

Does the lens support motorized adjustment?

The NP18ZL works with the host projector's lens shift system and supports the lens memory function, letting installers store and recall position, zoom and focus presets for different screen formats.

Is this lens suitable for permanent ceiling-mount installations?

Yes. At 1.9 lb it adds minimal weight to a ceiling mount, and lens shift allows fine image alignment after the projector is rigged, which simplifies commissioning in fixed AV installations.

What warranty applies?

Sharp NEC optional lenses are covered by the manufacturer's accessory warranty. Contact Creation Networks for current warranty terms and registration support on your projection system purchase.
