Sharp L2K-55ZM1 – 5.00-7.80:1 Powered Zoom Lens for PH2601QL/PH3501QL

Product Overview

The Sharp NEC L2K-55ZM1 is a 5.00–7.80:1 extra-long-throw powered zoom lens for the NP-PH2601QL and NP-PH3501QL large venue laser projectors. This long-throw projector lens is built for the most distant projection positions — rear booths in arenas, stadium concourses, performing arts centers, and large auditoriums — where the projector sits five to nearly eight times the image width from the screen. Motorized zoom, focus, and lens shift support remote projector alignment after rigging, and the recommended screen size range of 50 to 500 inches covers everything from training rooms to immersive large venue projection.

Product Description

The L2K-55ZM1 extends the throw range of Sharp NEC's PH-QL projector platform beyond the L2K-43ZM1, serving fixed installations where building geometry forces the projection booth far from the screen. Its 5.00–7.80:1 throw ratio and generous 1.6:1 zoom ratio give AV system designers significant flexibility: the same rigged position can serve different screen sizes, and image size can be re-trimmed remotely if the venue reconfigures.

The optical formula spans a 156.5–243.1mm focal length at a constant f/2.5 aperture, preserving brightness uniformity with the 26,000-lumen NP-PH2601QL and 35,000-lumen NP-PH3501QL laser projectors. Powered lens shift (±0.31% vertical, ±0.10% horizontal) provides fine image-position trim after the projector is locked into truss or structural mounts — a meaningful labor saving in commercial AV integration projects where the projector hangs high above the audience and physical access requires a lift.

The lens attaches directly to the PH-QL series bayonet with no adapters. Because all adjustments are motorized, initial calibration and ongoing alignment can be performed from the projector remote or a networked control system, which simplifies maintenance in auditorium projector installations with restricted rigging access. For shorter throw distances on the same projector platform, Creation Networks also carries the L2K-10F1 0.93:1 short-throw fixed lens and the L2K-43ZM1 3.91–5.52:1 powered zoom lens.

Key Features

• 1.6:1 Powered Zoom Range — Wide motorized zoom lets one rigged position serve multiple screen sizes without relocation.
• Powered Focus and Lens Shift — Remote adjustment (±0.31% vertical, ±0.10% horizontal shift) eliminates lift access for routine alignment.
• Constant f/2.5 Aperture — Maintains brightness and uniformity with high-output PH-QL series laser projection engines.
• PH-QL Series Compatibility — Direct bayonet mount for the Sharp NEC NP-PH2601QL and NP-PH3501QL projectors.
• 50 to 500 Inch Screen Range — Supports image sizes from meeting-room screens to very large venue canvases.

Typical Applications

Frequently Asked Questions

Which projectors does the L2K-55ZM1 fit?

The L2K-55ZM1 is designed for the Sharp NEC NP-PH2601QL and NP-PH3501QL large venue laser projectors and mounts directly to the lens bayonet without adapters. It is not compatible with other Sharp NEC projector lines.

How far can the projector sit from the screen?

With a 5.00–7.80:1 throw ratio, the projection distance equals 5.0 to 7.8 times the image width. For a 20-foot-wide image, the projector can be installed roughly 100 to 156 feet away — well suited to arena and large auditorium booth positions.

Are the adjustments motorized?

Yes. Zoom, focus, and lens shift are all powered, so image setup and re-alignment can be done from the remote or a networked AV control system without lift access to the rigged projector.

When should I choose this lens over the L2K-43ZM1?

Choose the L2K-55ZM1 when the throw distance exceeds about 5.5 times the image width. For positions between roughly 3.9 and 5.5 times the image width, the L2K-43ZM1 (also available at Creation Networks) is the correct optic.

Does Creation Networks help with lens selection and installation?

Yes. Our commercial AV team can run throw calculations for your venue, confirm compatibility, and coordinate professional installation for PH-QL series projector deployments.
