Sharp NP39ML-4K – 0.38:1 Ultra-Short-Throw Lens for NP-PX1005QL

Product Overview

The Sharp NEC NP39ML-4K is a 0.38:1 ultra-short-throw fixed projector lens engineered for the NP-PX1005QL series 4K UHD laser installation projectors. This bayonet-style ultra short throw lens lets integrators place a 10,000-lumen projector just inches from the screen, eliminating shadowing and long throw distances in space-constrained commercial projector installations. With motorized focus and an f/2 aperture, it is a precise optical solution for museums, immersive exhibits, digital signage projection, and staging environments where mounting depth is limited.

Product Description

Large-venue projection design often runs into a hard constraint: there is simply no room for a conventional throw distance. The NP39ML-4K solves this with a 0.38:1 throw ratio that produces images from 40 to 500 inches diagonal at extremely short projector-to-screen distances, opening up installation options behind scrims, inside exhibit enclosures, above doorways, and in shallow alcoves. The fixed focal length design (f = 5.64mm) maintains optical precision across the image, and motorized focus allows fine adjustment from the projector remote or control system after the unit is rigged or ceiling-mounted.

The bayonet-style mount supports quick lens exchange on compatible NEC NP-PX1005QL-B and NP-PX1005QL-W 4K UHD installation projectors, which is valuable for rental and staging operations that reconfigure optics between events. Wide operating tolerances (-25 to 50°C, 20–80% humidity) suit demanding deployment conditions, and at 2.72 kg the lens adds modest weight to rigging calculations. For AV system designers building projection mapping, simulation, or large-format immersive displays around the PX1005QL platform, this ultra-short-throw projector lens is the option that makes close-proximity 4K projection practical.

Key Features

• 0.38:1 Ultra-Short Throw Ratio — Projects large 4K images from extremely close range, eliminating presenter shadowing and freeing floor space in tight installations.
• Engineered for NP-PX1005QL Projectors — Verified compatibility with NEC NP-PX1005QL-B and NP-PX1005QL-W 4K UHD laser installation projectors.
• Motorized Focus — Focus adjusts remotely after rigging or ceiling mounting, so technicians do not need lift access for fine-tuning.
• Bayonet-Style Quick Exchange — The lens swaps quickly without tools, ideal for rental, staging, and multi-venue production workflows.
• Bright f/2 Aperture — A fast aperture preserves light output from high-brightness laser projectors for vivid large-format images.
• 40" to 500" Projection Size — Covers everything from compact exhibit displays to full-scale auditorium and mapping surfaces.
• Wide Environmental Tolerance — Operates from -25 to 50°C and 20–80% humidity for reliable performance in demanding venues.

Typical Applications

• Auditorium and large-venue projection with shallow mounting depth
• Broadcast studio backdrop and virtual set projection
• House of worship environmental projection
• Multi-purpose room and all-hands room projection where throw space is limited
• Government space simulation and visualization installations

Frequently Asked Questions

Which projectors is the NP39ML-4K compatible with?

The NP39ML-4K is designed for the Sharp NEC NP-PX1005QL series 4K UHD laser installation projectors, including the NP-PX1005QL-B and NP-PX1005QL-W variants. It is not interchangeable with other NEC lens mounts, so confirm your projector model before ordering.

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

With a 0.38:1 throw ratio, the lens produces images at distances starting around 1.6 feet, scaling up with screen size to a maximum 500-inch diagonal. This allows the projector to be mounted directly above or just in front of the projection surface.

Does the lens support lens shift or zoom?

The NP39ML-4K is a fixed focal length lens with motorized focus. It does not include zoom; image size is set by the projector-to-screen distance. Verify geometry with the NEC throw distance calculator during system design.

Is this lens suitable for rental and staging use?

Yes. The bayonet-style mount allows fast, tool-free lens exchange between events, and the lens tolerates a wide operating temperature and humidity range typical of staging environments.

Can focus be adjusted after the projector is rigged?

Yes. Motorized focus is controlled from the projector remote or an integrated control system, so no physical access to the lens is required after installation.

Does Creation Networks offer support for lens selection?

Yes. Our commercial AV team can verify throw distance, image size, and projector compatibility for your installation before purchase. Contact us with your room dimensions and screen size.
