FAQ

Q: What if the lens doesn't match the image size?

A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the corresponding throw ratio based on your actual installation distance. If you're unsure, send us the installation distance and screen size and our Zorsika technical team will recommend the right lens.

Q: My projector isn't on the 4-model list above. Can I still use the WD620?

A: The list contains verified models only, not the full range. Projectors from the same brand and generation often share the same lens interface. Send photos of your machine's nameplate and original lens to Zorsika technical support for confirmation—it's the safest approach.

Q: Can this lens replace the original manufacturer's lens?

A: The lens is the core of the projection optical path, directly determining clarity and color accuracy. Zorsika lenses (models listed in the specs table above) are matched item by item against original optical parameters (focal length, throw ratio, lens elements), with identical coating processes, delivering sharp imaging without soft edges. Ordinary replacement lenses typically use regular glass with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are manufactured according to original optical blueprints, with lens elements, coatings, and throw ratios matched item by item. Every lens undergoes resolution testing before shipment. Compared to original manufacturers, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika guarantees optical performance with verified data.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the invoice date.

• Optical Matching: Focal length, throw ratio, and lens elements matched to original specifications
• Resolution Testing: Each lens tested before shipment, MTF data available
• Coating Process: Lens coating same grade as original, minimizing light loss
• Stable Supply: Supports bulk procurement and project delivery

Bottom line: The lens is the optical core—don't gamble with image quality over price differences. Zorsika projector lenses are manufactured to original blueprints with overall advantages.

Note: Actual imaging performance depends on projector condition and installation environment. For bulk orders, we recommend requesting one sample lens for testing first.

Lens Replacement Precautions

• Power off before lens replacement: Always shut down and wait for the cooling fan to stop before removing or installing the lens to avoid damage from live operations.
• Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel when handling—don't touch the glass. For dust, use an air blower to gently blow; don't wipe with cloth.
• Focus before tightening: After installation, test focus first, then tighten the mounting screws. This prevents loosening over time that could cause image drift.
• Keep interfaces clean: Dust on bayonets and contacts causes poor connection. Clean them when replacing the lens for better reliability.
