ET-ELT31 Compatible Projector Model List (14 models, with Brightness/Resolution)

The following are verified compatible models for the ET-ELT31, each listed with its brightness and resolution. The compatible lens model for all is ET-ELT31:

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

About This Original Lens

The ET-ELT31 is a Long Throw lens manufactured by Panasonic. Its optical structure, lens coatings, and mechanical tolerances are matched to the original projector specifications, ensuring immediate installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from 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 4.02-7.20:1. 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's specifications.

Authenticity and Procurement Information

Zorsika supplies authentic Panasonic original lens ET-ELT31 through authorized channels, complete with original packaging and verifiable serial numbers. It is suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and similar applications.

• Authenticity Guarantee: Sourced from official manufacturer channels with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished units or sources of unknown origin.
• Compatibility Verification: Provide the projector model before ordering. Zorsika technical support will verify it against the compatible model list above to ensure proper fitment.
• Project Supply: The ET-ELT31 covers 14 models. For frequently used projects, schedule in advance to shorten lead times.
• Alternative Solutions: For budget-sensitive projects, Zorsika can also provide alternative lenses with equivalent specifications, with key parameters matching the original. Choose as needed.

Note: Actual imaging performance is affected by the projector'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: Original lenses are manufactured by Panasonic, with optical parameters and mechanical tolerances calibrated to the original projector, 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, offering advantages in budget and lead time. Zorsika supplies both lines; choose based on project requirements.

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

A: Compatibility is based on the projector's lens interface and panel/chip size. This article lists verified compatible models. Engineering projectors from the same generation and brand often share interfaces. If unsure, take a photo of the projector's nameplate and send it to Zorsika technical support for confirmation.

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 is 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 this model's focal range.

Q: How can I ensure the ET-ELT31 is authentic?

A: Zorsika supplies authentic products from official manufacturer channels, complete with original packaging and verifiable serial numbers. For bulk projects, channel credentials can be requested to ensure the units are not refurbished or second-hand.

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

A: Before disassembly, ensure the projector is powered off and wait for the cooling fan to stop. Handle 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.

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-induced damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
