NEC Display NP46ZL Short Throw Zoom Lens — 21.80 mm to 49.80 mm f/2.66, 2.3x Optical Zoom

Experience flexible projection with the NEC NP46ZL Short Throw Zoom Lens. Engineered for compact rooms and large venues alike, this lens delivers crisp, vivid images from close distances thanks to its bright f/2.66 aperture and a versatile 21.80–49.80 mm focal range. The 2.3x optical zoom offers seamless transitions between wide and tele projection without sacrificing edge-to-edge clarity, while the compact 9.1-inch length and 4.7-inch diameter simplify ceiling mounts and installation in tight spaces. The NP46ZL is built to perform in demanding environments—from classrooms to boardrooms and training facilities—delivering reliable brightness, color accuracy, and consistent focus across the screen. Its design emphasizes quiet operation, smooth manual adjustments, and robust construction that guards against wear in high-usage settings. With NEC engineering behind it, the lens maintains excellent throw consistency as room layouts change, ensuring you can reposition the projector without sacrificing image geometry. Whether you're delivering a lecture, presenting quarterly results, or running a digital signage display, NP46ZL gives you the flexibility to craft the perfect image without moving the projector.

• Versatile focal length and zoom: 21.80 mm to 49.80 mm with 2.3x optical zoom enables the same projector to cover a range of throw distances from tight classroom setups to larger lecture halls, preserving edge-to-edge sharpness and uniform brightness across the screen as you adjust zoom.
• Bright, fast performance: the f/2.66 aperture ensures better on-screen brightness and smoother auto-focus, helping maintain crisp text and vivid images in rooms with ambient light and during quick presentation transitions or dynamic video content.
• Compact, installer-friendly design: at 9.1 inches long and 4.7 inches in diameter, NP46ZL minimizes intrusion into ceiling cavities and allows flexible positioning for ideal throw distances, angle, and alignment.
• Neat integration with NEC ecosystems: designed to work seamlessly with NEC projectors, this lens helps maintain color fidelity, brightness consistency, and coordinated control of focus and zoom to deliver uniform performance across different displays.
• Durable construction for daily use: engineered for classroom, corporate, and event environments, it resists wear from frequent lens changes, stays aligned after adjustments, and supports long-term reliability under varying temperatures and vibration typical of installed spaces.
