About This Original Lens

Vivitek LNS-5STZ Short Zoom Lens

The LNS-5STZ Short Zoom is a standard throw lens manufactured by Vivitek as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original machine standards, ensuring plug-and-play installation with stable imaging. For installation environments with restricted projection distances (such as short-distance large-screen projection or wall-mounted ultra-short throw setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens features a throw ratio of 1.10-1.30:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for close-range, compact spaces), while a larger value requires a greater 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 Vivitek with optical parameters and body tolerances calibrated to the original machine, making them ideal 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 unit, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.

Q: How do 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.

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 is ideal for close-range, compact spaces), while a larger value requires a greater 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 range.

Q: How can I ensure the LNS-5STZ Short Zoom is genuine?

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

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

A: Always power off the projector and wait for the cooling fan to stop before disassembly; hold the lens by the 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 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 (such as impacts, water ingress, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the shipping document date.
