About This Original Lens

EIKI AH-B22030 Zoom Lens

The AH-B22030 Zoom is a standard throw lens manufactured by Eiki as original equipment. Its optical structure, lens coatings, and body tolerances are 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, ultra-short throw against a wall), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 1.20-1.50:1. 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 original 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 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 from 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. A smaller value produces a larger image (short/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-B22030 Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure they are not refurbished or second-hand disassembled units.

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, 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.
