About This Original Lens

EIKI AH-EC21020 Zoom Lens

The AH-EC21020 Zoom is a long throw lens manufactured by Eiki as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original equipment 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 generic lens.

This lens has a throw ratio of 1.30-3.02:1. 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 longer 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 the original equipment, 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 unit, 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 the same mount; if unsure, sending a photo of the unit's nameplate to Zorsika technical support for confirmation 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 close-range small spaces), while a larger value requires a longer 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-EC21020 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 the unit 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 barrel without touching the glass, use a blower for dust; after installation, perform a focus test before tightening the locking screws, and clean the mount and contacts as you go.

Q: How long is the lens warranty?

A: Zorsika offers a 12-month warranty on all projector lenses; for normal use and non-man-made damage (e.g., impacts, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
