About This Original Lens
The ET-ELW31 is a Standard Throw lens manufactured by Panasonic. Its optical structure, lens coatings, and mechanical tolerances are matched to the original projector specifications, ensuring plug-and-play 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 0.74-0.96:1. 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 authentic Panasonic original lens ET-ELW31 through authorized 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. Bulk projects can request channel credentials to eliminate refurbished units or sources of unknown origin.
- Compatibility Verification: Provide the projector model number before ordering; Zorsika technical support will verify against the compatible model list above to avoid installation issues.
- Project Supply: The ET-ELW31 covers 14 models. For frequent project use, 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 OEM, available for selection 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 options; choose based on project requirements.
Q: How can I confirm if 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. Projectors of 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 do I choose the throw ratio?
A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw 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 ensure the ET-ELW31 is authentic?
A: Zorsika supplies authentic products from OEM 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 glass elements. Use a blower to gently remove 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 offers 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.
