About This Original Lens

EIKI AH-AV21020 Zoom Lens

The AH-AV21020 Zoom is a standard throw lens manufactured by Eiki as original equipment. Its optical structure, lens coatings, and body tolerances are matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-throw large images, ultra-short-throw wall-mounted setups), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens offers a throw ratio of 0.86-1.25:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in compact spaces), while a larger value requires 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 Eiki, with optical parameters and body tolerances calibrated to original machine standards, 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, 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: 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 uncertain, 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 suited for compact spaces), while a larger value requires greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the AH-AV21020 Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, complete with original packaging and traceable serial numbers; bulk projects may request channel documentation to ensure the lens is not refurbished or a used disassembled 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 removal; 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 needed.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty on all projector lenses; normal use and non-manufacturer-caused damage (e.g., impact, water ingress, unauthorized disassembly) can be handled directly through after-sales service, with the warranty period starting from the shipping date on the invoice.
