About This Original Lens

NEC NP20ZL-4K Zoom Lens

The NP20ZL-4K Zoom is an original Long Throw lens manufactured by NEC, with optical construction, lens coatings, and body tolerances matched to original projector standards—ready to install and delivering stable imaging. For installation environments with restricted projection distances (e.g., short-distance large images, ultra-short-throw wall-mounted setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens offers a throw ratio of 3.54-5.36:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small 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.

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 the original, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.

Q: How can 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 of the same generation and brand often share the same mount—if unsure, send a photo of the nameplate 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 short distances in small 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 is the NP20ZL-4K Zoom guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure the lens is not refurbished or a used pulled part.

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

A: Before removal, ensure the projector is powered off and the cooling fan has stopped; hold the lens barrel without touching the glass, use a blower for dust; after installation, perform a focus test 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 provides 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.
