Sharp L2K-43ZM1 – 3.91-5.52:1 Powered Zoom Lens for PH2601QL/PH3501QL

Product Overview

The Sharp NEC L2K-43ZM1 is a 3.91–5.52:1 long-throw powered zoom lens built for the NP-PH2601QL and NP-PH3501QL large venue laser projectors. This long-throw projector lens lets integrators rig the projector at the back of an auditorium, arena, or projection booth while still filling very large screens, with motorized zoom, focus, and lens shift for remote alignment after installation. It is the standard optic for long-distance projector installation in venues where the projection position is fixed far from the screen.

Product Description

In large venue AV system design, throw distance is usually dictated by the building, not the integrator. The L2K-43ZM1 addresses installations where the projector must sit roughly four to five and a half times the image width away from the screen — typical of rear-of-house projection booths in auditoriums, performing arts centers, houses of worship, and arena bowls. Its 3.91–5.52:1 throw ratio range provides flexibility to fine-tune image size without physically relocating a rigged projector.

Because the lens serves Sharp NEC's 26,000-lumen NP-PH2601QL and 35,000-lumen NP-PH3501QL laser projectors, every adjustment is motorized. Powered zoom and powered focus allow precise image setup from the remote control or a networked control system, and powered lens shift trims image position after the projector is locked into truss or structural mounting — eliminating the need to access the unit at height for routine alignment. This is a significant labor advantage in commercial AV integration projects where the projector hangs 30 feet or more above the floor.

The lens mounts directly to the PH-QL series bayonet with no adapters and is covered by a 1-year limited parts and labor warranty from Sharp NEC. For the same projector platform, Creation Networks also offers the L2K-10F1 0.93:1 short-throw fixed lens and the L2K-55ZM1 5.00–7.80:1 extra-long-throw powered zoom lens, letting system designers standardize on one projector body across rooms with very different throw geometries.

Frequently Asked Questions

Which projectors accept the L2K-43ZM1 lens?

The L2K-43ZM1 is verified by Sharp NEC for the NP-PH2601QL and NP-PH3501QL large venue laser projectors. It mounts directly to the lens bayonet with no adapters and is not interchangeable with other Sharp NEC projector series.

How far from the screen should the projector be installed with this lens?

With a 3.91–5.52:1 throw ratio, the projection distance is roughly 3.91 to 5.52 times the image width. For a 20-foot-wide image, the projector can be positioned approximately 78 to 110 feet from the screen — typical of rear projection booths in auditoriums and arenas.

Are zoom, focus, and shift motorized?

Yes. All adjustments are powered, so the image can be sized, focused, and positioned from the remote or a networked AV control system without accessing the projector at height.

What warranty covers this lens?

Sharp NEC provides a 1-year limited parts and labor warranty. Creation Networks can advise on extended coverage and commercial installation support.

What other lenses are available for the same projectors?

Creation Networks carries the full L2K family for the PH-QL series, including the L2K-10F1 0.93:1 short-throw fixed lens and the L2K-55ZM1 5.00–7.80:1 extra-long-throw powered zoom lens, so a single projector platform can be deployed across rooms with different throw distances.
