ET-EMW300 Compatible Projector Model List (19 models, with Brightness/Resolution)

The following are verified compatible projector models for the ET-EMW300, each listed with brightness and resolution. The compatible lens model for all is ET-EMW300:

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

About This Original Lens

The ET-EMW300 is a 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 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 0.550-0.690:1. 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 & Purchasing Information

Zorsika supplies authentic Panasonic ET-EMW300 original lenses through authorized channels, complete with original packaging and verifiable serial numbers. This is suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and similar applications.

• Authenticity Guarantee: Sourced from official, authorized channels with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished or untraceable units.
• Compatibility Verification: Provide the projector model number before ordering. Zorsika technical support will verify it against the compatible model list above to avoid installation issues.
• Project Supply: The ET-EMW300 covers 19 models. For common projects, scheduling in advance can 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 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 projector, making it 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 options; choose based on project requirements.

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

A: Compatibility is determined by the projector's lens mount and panel/chip size. This article lists verified compatible models. Projectors from the same generation and brand often share mounts. If unsure, taking a photo of the projector's nameplate and sending it to Zorsika technical support for confirmation is the safest approach.

Q: How do I 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 close 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 be sure the ET-EMW300 is authentic?

A: Zorsika supplies authentic products from official channels, complete with original packaging and verifiable serial numbers. Bulk projects can request channel credentials 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 glass 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), contact after-sales service directly. The warranty period is based on the shipping document date.
