Sharp L2K-10F1 – 0.93:1 Short-Throw Fixed Lens for PH2601QL/PH3501QL

Product Overview

The Sharp NEC L2K-10F1 is a 0.93:1 short-throw fixed projector lens engineered for the NP-PH2601QL and NP-PH3501QL large venue laser projectors. With a near 1:1 throw ratio, this short-throw projector lens lets integrators position the projector close to the screen — a critical requirement in auditoriums, broadcast studios, and staging environments where rigging distance is limited. It supports projection screen sizes from 50 to 500 inches, covering everything from a multi-purpose room to large-scale immersive installations.

Product Description

Lens selection determines where a large venue projector can physically live in a room, and the L2K-10F1 solves the short-distance problem for Sharp NEC's PH-QL series. Its 0.93:1 throw ratio produces an image roughly as wide as the projector's distance from the screen, allowing close-proximity projector installation behind a proscenium, above a stage edge, or in a shallow projection booth where longer-throw optics would not fit the geometry.

The fixed optical design uses a 28.95mm focal length with an f/2.5 aperture, delivering consistent edge-to-edge performance for the high-output laser projectors it serves. Limited lens shift (±0.27% vertical, ±0.08% horizontal) provides fine alignment trim after mounting, which is typical for short-throw optics in this class. Because the recommended screen size spans 50 to 500 inches, the same lens supports commercial AV integration projects ranging from training room screens to very large blended canvases in museums and visitor attractions.

As a professional interchangeable projector lens, the L2K-10F1 mounts directly to the NP-PH2601QL (26,000 lumens) and NP-PH3501QL (35,000 lumens) projector bodies with no adapters. At 15 pounds and 18.3 inches long, it should be factored into rigging and mount load calculations during AV system design. For projects requiring different throw distances on the same projector platform, Creation Networks also carries the L2K series powered zoom lenses, including the L2K-43ZM1 and L2K-55ZM1 long-throw options.

Key Features

• 0.93:1 Short-Throw Ratio — Positions the projector close to the screen for shallow booths, stage edges, and space-constrained venues.
• PH-QL Series Compatibility — Mounts directly to the Sharp NEC NP-PH2601QL and NP-PH3501QL large venue laser projectors.
• 50 to 500 Inch Screen Range — Covers training room screens through very large immersive and staging canvases.
• f/2.5 Aperture — Maintains image brightness and uniformity with high-output laser projection engines.
• Fixed 28.95mm Focal Length — Purpose-built optical formula delivers consistent edge-to-edge sharpness for fixed installations.
• Alignment Trim via Lens Shift — ±0.27% vertical and ±0.08% horizontal shift allows fine image positioning after rigging.

Typical Applications

Frequently Asked Questions

Which projectors does the L2K-10F1 fit?

The L2K-10F1 is designed for the Sharp NEC NP-PH2601QL and NP-PH3501QL large venue laser projectors. It mounts directly to the lens bayonet with no adapters. It is not compatible with other Sharp NEC projector series.

How close can the projector sit to the screen with this lens?

With a 0.93:1 throw ratio, the projection distance is roughly 0.93 times the image width. For example, a 16.4-foot-wide image (approximately a 225-inch 16:9 screen) requires the projector to sit about 15.3 feet from the screen.

Does this lens support lens shift?

Yes, within the narrow range typical of short-throw optics: ±0.27% vertical and ±0.08% horizontal. Plan the mounting position carefully during AV system design, since major image positioning must come from physical placement rather than shift.

Is installation by an AV integrator recommended?

Yes. The lens weighs 15 pounds and serves projectors typically rigged on truss or structural mounts in auditoriums and staging environments. Professional installation ensures correct load handling, alignment, and calibration.

What if I need a longer throw distance on the same projector?

Sharp NEC offers the L2K lens family in multiple throw ranges. Creation Networks stocks the L2K-43ZM1 (3.91–5.52:1) and L2K-55ZM1 (5.00–7.80:1) powered zoom lenses for long-throw installations on the same PH-QL series projectors.
