ET-ELU20 Compatible Projector Model List (6 models total, with brightness/resolution)

The following are verified compatible projector models for the ET-ELU20, each listed with brightness and resolution; the compatible lens model for all is ET-ELU20:

Note: Brightness/resolution data is taken from the model database (subject to the machine's nameplate/manual); lens compatibility is based on the machine's lens interface and panel/chip size. For models not on the list, please contact Zorsika technical support for confirmation.

About This Original Lens

The ET-ELU20 is an Ultra Short Throw lens manufactured by Panasonic. Its optical structure, lens coatings, and mechanical tolerances are matched to the original projector specifications, ensuring ready-to-use installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image over a short distance, ultra-short throw close to the wall), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 0.330-0.353:1. Throw Ratio = Projection Distance ÷ Image Width: a smaller value produces a larger image (suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Authenticity and Procurement Information

Zorsika supplies the Panasonic original lens ET-ELU20 through authentic channels, complete with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and similar applications.

• Authenticity Guarantee: Sourced through official OEM channels, with original packaging and serial numbers. For bulk projects, channel credentials can be provided upon request to eliminate refurbished units and sources of unknown origin.
• Compatibility Verification: Provide the machine model before ordering. Zorsika technical support will verify it against the compatible model list above to avoid installation issues.
• Project Supply: The ET-ELU20 covers 6 models. For frequently used projects, scheduling in advance can shorten delivery times.
• Alternative Solutions: If budget is a concern, Zorsika can also provide alternative lenses with equivalent specifications, with key parameters matching the OEM, for selection as needed.

Note: Actual imaging performance is affected by the machine's condition and installation environment. For large bulk orders, it is recommended to first obtain one unit for testing.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: The original lens is manufactured by Panasonic, with optical parameters and mechanical tolerances calibrated to the original machine, 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 matching the original machine, offering advantages in budget and delivery time. Zorsika supplies both lines; choose based on project requirements.

Q: How can I confirm this lens will work with my machine?

A: Compatibility is based on the machine's lens interface and panel/chip size; this article lists verified compatible models. Engineering projectors of the same generation and brand often share interfaces. If unsure, taking a photo of the machine's nameplate and sending it to Zorsika technical support for confirmation is the safest approach.

Q: How to choose the Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.

Q: How can I ensure the ET-ELU20 is authentic?

A: Zorsika supplies authentic products through OEM channels, with original packaging and verifiable serial numbers. For bulk projects, channel credentials can be provided upon request to ensure the units are not refurbished or second-hand salvage parts.

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

A: Before disassembly/assembly, be sure to power off the machine and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding contact with the lens elements. Use a blower to gently remove any dust. After installation, perform a focus test before tightening the mounting screws, and clean the mount and contacts while you're at it.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), you can directly contact after-sales service. The warranty period is based on the date of the shipping document.
