About This Original Lens
EIKI AH-B22020 Zoom Lens
The AH-B22020 Zoom is a Standard Throw lens manufactured by Eiki as an OEM product. Its optical structure, lens coatings, and body tolerances are matched to original machine 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 wall-mounted setups), selecting the correct throw ratio is more critical than choosing a generic lens.
This lens has a throw ratio of 1.02-1.36:1. 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 original machine standards, making them 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 machine, 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: 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 select 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 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 range.
Q: How is the AH-B22020 Zoom guaranteed to be genuine?
A: Zorsika supplies genuine products through authorized OEM channels, with original packaging and traceable serial numbers; channel documentation can be requested for bulk projects to ensure they are not refurbished or used parts.
Q: What should I pay attention to when replacing the lens?
A: Before removal, 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 you go.
Q: What is the warranty period for the lens?
A: Zorsika provides a 12-month warranty on all projector lenses; normal use and non-manual damage (e.g., impact, water ingress, unauthorized disassembly) can be handled directly through after-sales service, with the warranty period based on the shipping document date.
