About This Original Lens

EIKI AH-AV21030 Zoom Lens

The AH-AV21030 Zoom is an original Long Throw lens manufactured by Eiki. 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-distance large images, wall-mounted ultra-short throw), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 1.24-2.01:1. Throw ratio = projection distance ÷ image width: a smaller value means a larger image (suitable for short distances in 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 Eiki, with optical parameters and body tolerances calibrated to original machine standards, making them 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, offering advantages in budget and lead time. Zorsika supplies both options, so 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; verified compatible models are listed in this article. Projectors of 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 choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short throw/ultra-short throw for close-range small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal length range.

Q: How can I ensure the AH-AV21030 Zoom is genuine?

A: Zorsika supplies genuine products through authorized channels, with original packaging and traceable serial numbers. For bulk projects, channel documentation can be requested 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/installation. 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 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-artificial damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
