About This Original Lens

EIKI AH-A21010 Zoom Lens

The AH-A21010 Zoom is an original Long Throw lens manufactured by Eiki. Its optical structure, lens coatings, and body tolerances are matched to original projector standards, ensuring ready-to-use installation and stable imaging. For installation environments with restricted projection distances (e.g., short-distance large images, ultra-short throw near walls), selecting the correct 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: a smaller value produces a larger image (suitable for short distances/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 an alternative lens?

A: Original lenses are manufactured by Eiki, with optical parameters and body tolerances calibrated to original projector standards, suitable 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 benchmarked to the original, offering advantages in budget and lead time. Zorsika can supply both options; 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; this article lists verified compatible models. Projectors of the same generation and brand often share mounts. If unsure, take a photo of 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 suitable for short distances/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's focal length range.

Q: How can I ensure the AH-A21010 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 requested to ensure the unit is not refurbished or a used disassembled part.

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

A: Before removal/installation, ensure the projector is powered off and the cooling fan has stopped; 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.
