About This Original Lens

Appotronics AL-EL300LZ Zoom Lens

The AL-EL300LZ Zoom is an original Long Throw lens manufactured by Appotronics. Its optical structure, lens coatings, and body tolerances are all matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distances (e.g., projecting large images from short distances or ultra-short-throw wall-mounted setups), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 2.86-4.85:1. 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 a replacement lens?

A: Original lenses are manufactured by Appotronics, with optical parameters and body tolerances calibrated to original machine standards, making them ideal for projects with strict OEM consistency requirements. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matched to the original, offering advantages in budget and lead time. Zorsika supplies both options, so 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; verified compatible models are listed in this article. Engineering projectors of the same generation and brand often share the same mount. If unsure, take a photo of the unit's 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-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 length range.

Q: How is the AL-EL300LZ Zoom guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, complete with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects, ensuring no refurbished or second-hand disassembled units.

Q: What should I pay attention to when replacing the lens?

A: Before disassembly, ensure the projector is powered off and the cooling fan has stopped; hold the lens by the barrel without touching the glass, and 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: What is the warranty period for the lens?

A: Zorsika offers 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.
