About This Genuine Lens

Appotronics EL300LZ Zoom Lens

The EL300LZ Zoom is a genuine Appotronics Long Throw lens. Its optical structure, lens coating, and chassis tolerance are all matched to original machine standards—ready to install with stable imaging performance. For installations with limited projection distance (such as large images from short distances, or wall-mounted ultra-short throw setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 2.86-4.85:1. Throw ratio = projection distance ÷ screen width: smaller values produce larger images (suitable for small spaces at close range), while larger values require greater installation distance. Work backwards from your actual installation distance and screen size to determine the required throw ratio range, then match it to this model.

Authenticity & Procurement Notes

Zorsika offers genuine Appotronics EL300LZ Zoom original lens through authorized channels, complete with factory packaging and traceable serial numbers, suitable for bulk procurement and project supply for engineering projection, conference rooms, classrooms, and similar applications.

• Authenticity Guarantee: Factory-authorized channels with original packaging and serial numbers; batch projects can request channel documentation to ensure no refurbished or unverified units.
• Compatibility Check: Provide the projector model before ordering; Zorsika technical team will verify against the model compatibility list above to ensure proper fit.
• Project Supply: EL300LZ Zoom covers 10 projector models; common projects can be scheduled in advance to reduce lead times.
• Alternative Options: For budget-sensitive projects, Zorsika also offers alternative lenses of the same specifications with key parameters aligned to the original factory; choose as needed.

Note: Actual imaging performance depends on the projector condition and installation environment; for large orders, it is recommended to test one unit first before bulk deployment.

Frequently Asked Questions

Q: How do I choose between original and alternative lenses?

A: Original lenses are manufactured by Appotronics with optical parameters and machine tolerances calibrated to original specs, suitable for projects with strict OEM consistency requirements; Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matching the original, offering advantages in cost and delivery time. Zorsika supplies both options—choose based on your project requirements.

Q: How do I confirm this lens will work on my machine?

A: Verify based on the projector's lens mount interface and panel/chip size; this article lists validated compatible models. Same-generation engineering projectors from the same brand typically share compatible interfaces. If unsure, take a photo of the projector nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the right throw ratio?

A: Throw ratio = projection distance ÷ screen width. A smaller ratio produces a larger image (short-throw/ultra-short-throw suitable for close-range small spaces), while a larger ratio requires greater installation distance. Calculate the required throw ratio range based on your installation distance and screen dimensions, then select the corresponding focal length for this model.

Q: How does Zorsika guarantee authenticity for the EL300LZ Zoom?

A: Zorsika provides genuine products through original factory channels, complete with factory packaging and traceable serial numbers; batch projects can request channel documentation to ensure no refurbished or second-hand disassembled units.

Q: What should I watch out for when replacing the lens?

A: Always power off and wait for the cooling fan to stop before removal or installation; hold the lens by the barrel without touching the glass, and gently blow away any dust with an air bulb; after installation, test focus before tightening the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika offers 12-month warranty on all projector lens models; normal use with non-human damage (such as impacts, water ingress, or unauthorized disassembly) can be handled by contacting after-sales service, with the warranty period based on the shipping document date.
