NEC Display NP49ZL Ultra Long Throw Zoom Lens for Projectors

The NEC NP49ZL Ultra Long Throw Zoom Lens is engineered to redefine projection versatility, delivering sharp, bright images from extended distances without compromising color accuracy or edge-to-edge clarity. With a focal range of 21.80 mm to 49.80 mm and a fast f/2.66 aperture, this lens is purpose-built for large venues, auditoriums, classrooms, museums, and conference rooms where screen size and throw distance demand precise framing. Its compact 9.6" length and 4.4" diameter keep installation neat while maximizing image quality, making it a trusted accessory for demanding projection setups that require reliability, speed, and consistency.

• 2.3x optical zoom for flexible framing: Frame content perfectly from the projector’s fixed position, enabling both wide audience views and close-up detail without shifting equipment.
• Bright f/2.66 opening for strong brightness: Maintain vivid, high-contrast images across the zoom range, reducing the need for excessive brightness or additional lighting in medium to large spaces.
• Compact, practical design: At 9.6 inches in length and 4.4 inches in diameter, it’s easy to install in tight racks or ceilings, while preserving a sturdy, vibration-resistant mount.
• Premium optical performance: Expect edge-to-edge sharpness with controlled distortion, consistent color fidelity, and reliable focus across the entire zoom range for professional presentations and immersive content.
• NEC-optimized compatibility: Specifically designed for NEC projector systems, offering seamless integration, dependable operation, and streamlined calibration for busy environments.

how to install NEC Display NP49ZL

• Prepare the projector: Power down and unplug the projector. Ensure you have an appropriate mounting surface and clear access to the lens mount.
• Detach the existing lens (if applicable): If your setup already uses a different lens, carefully remove it following the projector’s service manual to avoid any damage.
• Align with the lens mount: Position the NP49ZL so that its mounting tabs engage the projector’s lens mount. Align carefully to prevent cross-threading or misalignment.
• Secure the lens: Gently screw or lock the lens into place according to the NEC mounting procedure. Use even tightening to avoid stress on the mount.
• Initial calibration: Power on the projector and perform a basic alignment. Use the lens zoom and focus controls to frame the screen area, then fine-tune keystone and geometry in the projector menu if needed.
• Fine-tune focus and zoom: With content displaying, adjust the zoom ring to frame the image precisely, then rotate the focus ring until edge-to-edge sharpness is achieved.
• Calibration check: Verify color accuracy and brightness uniformity across the screen. If your environment requires, run any lens shading corrections or image corrections provided by the projector’s menu.
• Secure operation: Confirm that all cables are clear of the lens, the lens is firmly seated, and there are no obstructions that could impact movement or heat dissipation.
