About This Original Lens

NEC NP31ZL Zoom Lens

The NP31ZL Zoom is a Standard Throw lens manufactured by NEC as original equipment. Its optical construction, lens coatings, and body tolerances are matched to original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted throw distances (e.g., short-distance large projection, ultra-short-throw wall mounting), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 0.75-0.93:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances and small spaces), while a larger value requires a longer installation distance. Work backward from your on-site installation distance and screen size to determine the required throw ratio range, then match it to this model.

FAQ

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

A: Original lenses are manufactured by NEC with optical parameters and body tolerances calibrated to the original projector, making them suitable for projects with strict OEM consistency requirements. Zorsika replacement 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 can supply 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, take a photo of the unit's nameplate and send it to Zorsika technical support for confirmation—this is the safest approach.

Q: How do I choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short-throw/ultra-short-throw is ideal for close-range small spaces), while a larger value requires a longer installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal length.

Q: How can I be sure the NP31ZL Zoom is genuine?

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

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

A: Before removal or installation, always power off the projector and wait for the cooling fan to stop. Hold the lens by the barrel without touching the glass; use a blower for dust. After installation, test focus first 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. Normal use and non-man-made damage (e.g., impact, water ingress, unauthorized disassembly) can be handled directly through after-sales service; the warranty period is based on the shipping invoice date.
