About This Original Lens

EIKI AH-B21010 Zoom Lens

The AH-B21010 Zoom is a Standard Throw lens manufactured by Eiki as original equipment. Its optical structure, lens coatings, and body tolerances are all matched to original projector 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 1.50-2.00:1. 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. Work backward from your on-site installation distance and screen size to determine the required throw ratio range, 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 projector standards—ideal 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; choose according to your project requirements.

Q: How can 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 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 small spaces at close range); the larger the value, the greater the installation distance required. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal range.

Q: How is the AH-B21010 Zoom guaranteed to be 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 lens is not refurbished or a used pulled 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, and use a blower for dust. After installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.

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.
