About This Original Lens

EIKI AH-E23020 Zoom Lens

The AH-E23020 Zoom is an original Long Throw lens from Eiki. Its optical structure, lens coatings, and body tolerances are all matched to original machine 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 wall-mounted setups), choosing the correct throw ratio is more critical than selecting a generic lens.

This lens has a throw ratio of 4.31-7.35:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (suitable for short distances in small spaces); the larger the value, the longer the required 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 Eiki, with optical parameters and body tolerances calibrated to the original machine, suitable 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 machine, 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 determined by the projector's lens mount and panel/chip size; verified compatible models are listed in this article. Projectors of the same generation and brand often share the same mount. If unsure, photograph the 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. The smaller the value, the larger the image (short-throw/ultra-short-throw suits close-range small spaces); the larger the value, the longer the required 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 be sure the AH-E23020 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 to ensure the lens 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 barrel without touching the glass, 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 (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.
