About This Original Lens

NEC NP56ZL Ultra Long Zoom Lens

The NP56ZL Ultra Long Zoom is a long throw lens produced by NEC. Its optical structure, lens coatings, and body tolerances are matched to the original projector specifications, ensuring ready-to-use installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from a short distance, ultra-short throw near a wall), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 3.95-7.51:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Authenticity and Procurement Information

Zorsika provides authentic NEC original lens NP56ZL Ultra Long Zoom through authorized channels, with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and other projects.

• Authenticity Guarantee: Sourced through official OEM channels, with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished units and sources of unknown origin.
• Compatibility Verification: Provide the projector model before ordering; Zorsika technical support will verify against the compatible model list above to avoid installation issues.
• Project Supply: The NP56ZL Ultra Long Zoom covers 4 models. For common projects, schedule in advance to shorten delivery times.
• Alternative Solutions: If budget-sensitive, Zorsika can also provide alternative lenses with the same specifications, with key parameters matching the OEM, for selection as needed.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For large quantities, it is recommended to first obtain one unit for testing.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: Original lenses are produced by NEC, with optical parameters and body tolerances calibrated to the original projector, suitable for projects with strict requirements for OEM consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matching the original, offering advantages in budget and delivery time. Zorsika supplies both lines; choose based on project requirements.

Q: How to confirm if this lens will work with my projector?

A: Compatibility is based on the projector's lens interface and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share interfaces. If unsure, take a photo of the projector's nameplate and send it to Zorsika technical support for confirmation.

Q: How to select the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short/ultra-short throw suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.

Q: How to ensure the NP56ZL Ultra Long Zoom is authentic?

A: Zorsika provides authentic products from OEM channels, with original packaging and verifiable serial numbers. Bulk projects can request channel credentials to ensure they are not refurbished or second-hand parts.

Q: What should I pay attention to when replacing the lens?

A: Before disassembly, be sure to turn off the projector and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding touching the lens elements. Use a blower to gently remove any dust. After installation, perform a focus test first, then tighten the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika offers a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
