About This Original Lens

NEC NP37ZL Zoom Lens

The NP37ZL Zoom is a Long Throw lens manufactured by NEC as an OEM product. 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 restricted projection distance (e.g., short-distance large images, wall-mounted ultra-short throw), choosing the right throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 1.52-2.92:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (ideal for short distances in small spaces); the larger the value, the greater the installation distance required. 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 an alternative lens?

A: Original lenses are manufactured by NEC, with optical parameters and body tolerances calibrated to the original equipment, making them 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 the original, offering advantages in budget and lead time. Zorsika can supply both options; choose based on your project requirements.

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

A: Compatibility is based on the 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. The smaller the value, the larger the image (short throw/ultra-short throw suits short distances in small spaces); the larger the value, the greater the installation distance required. 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 range.

Q: How can I ensure the NP37ZL Zoom is genuine?

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

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

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

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-manual damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
