About This Original Lens

NEC NP18ZL-4K Zoom Lens

The NP18ZL-4K Zoom is an original NEC Long Throw lens, with optical construction, lens coatings, and body tolerances matched to original projector standards—ready to install and delivering stable imaging. For installation environments with constrained projection distances (e.g., short-distance large images, ultra-short-throw wall mounting), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens offers a throw ratio of 1.71-2.25:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in compact spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

Note: Actual imaging performance is affected by projector condition and installation environment; it is recommended to test one unit before large-scale procurement.

FAQ

Q: How do I choose between an original lens and an alternative lens?

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

Q: How do I confirm this lens works with my projector?

A: Compatibility is determined by the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors from the same generation and brand often share mounts; if unsure, photograph the nameplate and send it to Zorsika technical support for confirmation.

Q: How do I select the throw ratio?

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

Q: How can I ensure the NP18ZL-4K Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; bulk projects can request channel documentation to ensure no refurbished or second-hand units.

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

A: Before removal, power off the projector and wait for the cooling fan to stop; hold the lens barrel without touching the glass, use a blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.

Q: What is the warranty period for the lens?

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