FAQ
Q: The lens doesn't match the screen size. What should I do?
A: First verify the lens interface and optical axis position of your projector model, then select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send your installation distance and screen dimensions to Zorsika technical support and we'll recommend the right lens.
Q: My projector is not on the 3-model list above. Can I still use WJ143?
A: The list represents verified models only, not an exhaustive inventory. Projectors from the same brand and generation often share lens interfaces. Send photos of your machine nameplate and original lens to Zorsika technical support for confirmation.
Q: Can this lens replace the original OEM lens?
A: The lens is the core of the projector optical path and directly determines clarity and color accuracy. Zorsika lenses (models listed in the specs table above) are engineered to match OEM optical parameters item by item—focal length, throw ratio, and lens elements—with consistent lens coating工艺. The result: sharp imaging with no edge blur. Generic replacement lenses typically use ordinary glass elements with insufficient coating layers, resulting in noticeable brightness loss and color deviation. For engineering and exhibition applications, Zorsika is the recommended choice.
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens elements, coatings, and throw ratios matched item by item. Every unit undergoes resolution testing before shipment. Compared to OEM: shorter lead times and better overall value. Compared to other replacement lenses: guaranteed optical performance backed by test data.
Q: What is the lens warranty period?
A: All Zorsika projector lenses are covered by a 12-month warranty. Normal use and non-human-induced damage (such as impacts, water ingress, or unauthorized disassembly) can be handled through after-sales service. The warranty period is calculated from the shipping document date.
What Zorsika Lenses Offer You

Zorsika's equivalent alternative model, compatible with 3 models including Eiki EK-900LU, EK-1000LU, EK-1300LU; enter WJ143 in the search system on Zorsika's official website to find the complete model compatibility list.
- Optical Match: Focal length, throw ratio, and lens elements matched to OEM specs
- Resolution Testing: Individually tested before shipment, MTF data available
- Coating Process: Lens coating matches OEM grade to minimize light loss
- Stable Supply: Supports bulk purchasing and project-based supply
Bottom line: The lens is the optical core — don't compromise image quality for a price difference. Zorsika projector lenses are manufactured to original OEM blueprints, delivering overall superior advantages.
Note: Actual imaging performance depends on projector condition and installation environment. For bulk orders, it is recommended to test one unit first.
What to Watch for When Replacing the Lens
- Power off first: Always shut down and wait for the cooling fan to stop before removing or installing the lens. Avoid live operations to prevent interface damage.
- Don't touch the glass: Fingerprints and oils directly affect image quality. Hold the lens barrel, not the glass. Use an air blower for dust — no dry wiping.
- Focus before locking: After positioning, test focus first, then tighten the mounting screws. Loose screws over time can cause image drift.
- Keep interfaces clean: Dust on mounts and contacts causes poor connection. Clean them when replacing the lens for better reliability.
