About This Original Lens

NEC NP39ML-4K Fixed Lens

The NP39ML-4K Fixed is an Ultra Short Throw lens manufactured by NEC. Its optical structure, lens coatings, and body tolerances are all matched to original equipment standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large-screen projection, wall-mounted ultra-short throw), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens features a throw ratio of 0.38:1. 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 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 a replacement lens?

A: Original lenses are manufactured by NEC, with optical parameters and body tolerances calibrated to the original unit, making them ideal for projects with strict requirements for OEM consistency. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original unit, 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 from the same generation and brand often share the same mount. If unsure, photograph the unit's nameplate and send it to Zorsika technical support for confirmation—it's 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 short distances and 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's focal length range.

Q: How can I ensure the NP39ML-4K Fixed is genuine?

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

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

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

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 our after-sales service directly. The warranty period is based on the shipping document date.
