About This Original Lens

EIKI AH-D21010 Zoom Lens

The AH-D21010 Zoom is an original Long Throw lens manufactured by Eiki. Its optical structure, lens coatings, and body tolerances are matched to original unit standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distances (e.g., short-distance large images, wall-mounted ultra-short throw), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 1.87-2.56:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (ideal for short distances in small spaces); the larger the value, the greater the installation distance required. 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 unit 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 matched to the original unit, 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: Refer to 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 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. The smaller the value, the larger the image (short throw/ultra-short throw suits close-range small spaces); the larger the value, the greater the installation distance required. 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-D21010 Zoom is genuine?

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

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

A: Before disassembly, 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 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-man-made damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping document date.
