About This Original Lens

NEC NP31ZL-4K Zoom Lens

The NP31ZL-4K Zoom is a standard throw lens manufactured by NEC as an OEM product. Its optical structure, lens coatings, and body tolerances are matched to original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large images, ultra-short throw near walls), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 0.74-0.93:1. 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 longer 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 standards, ideal 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 matched to original units, 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: Verify based on 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 nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the throw ratio?

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

Q: How can I ensure the NP31ZL-4K Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with OEM packaging and traceable serial numbers; channel documentation can be requested for bulk projects to ensure they are not refurbished or used parts.

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, perform a focus test before tightening the locking screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty on all projector lenses; for normal use without 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.
