About This Original Lens
EIKI AH-EC21030 Zoom Lens
The AH-EC21030 Zoom is a long throw lens manufactured by Eiki. Its optical structure, lens coatings, and body tolerances are all matched to original equipment standards, ensuring plug-and-play installation and stable imaging. In installation environments with restricted projection distances (e.g., short-distance large images, wall-mounted ultra-short throw), choosing the correct throw ratio is more critical than selecting a generic lens.
This lens has a throw ratio of 1.46-2.95:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your on-site 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 the original equipment, making them suitable for projects with strict requirements for original consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount benchmarked 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 as the standard; this article lists verified compatible models. 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—this is the safest approach.
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 suits 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's focal length range.
Q: How can I ensure the AH-EC21030 Zoom is genuine?
A: Zorsika supplies genuine products through original channels, complete with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure the product is not refurbished or a used disassembled part.
Q: What should I pay attention to when replacing the lens?
A: Before disassembly, be sure to power off the projector and wait for the cooling fan to stop; hold the lens by the 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 a final step.
Q: How long is the lens warranty?
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.
