Common Questions

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

A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the matching throw ratio based on your actual installation distance. If you're unsure, send your installation distance and screen dimensions to Zorsika technical support and we'll help you find the right recommendation.

Q: My machine isn't on the 5-model list above. Can I still use WJ145?

A: That list represents only verified models, not the complete range. Machines from the same brand and generation often share lens interfaces. Send a photo of your projector nameplate and original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the OEM one?

A: The lens is the core of the projection light path, directly determining sharpness and color accuracy. Zorsika lenses (models as listed in the spec table above) are itemized against OEM optical specifications—focal length, throw ratio, lens elements—with matching coating processes, delivering sharp imaging without soft edges. Ordinary replacement lenses typically use standard 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 OEM?

A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens elements, coatings, and throw ratios all matching item by item. Every unit undergoes resolution testing before shipment. Compared to OEM, we offer shorter lead times and better overall value. Compared to other replacement lenses, our optical quality is backed by measurable data.

Q: What is the warranty period for the lens?

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

• Optical matching: Focal length, throw ratio, and lens elements matched to OEM specifications
• Resolution testing: Every unit tested before shipment, MTF data available
• Coating process: Lens coating at the same level as OEM, minimizing light loss
• Stable supply: Supports bulk purchasing and project fulfillment

Bottom line: The lens is the optical core—don't gamble with image quality over a price difference. Zorsika projector lenses are manufactured according to OEM blueprints, delivering superior overall value.

Note: Actual imaging performance may be affected by projector condition and installation environment. It is recommended to test one unit before bulk purchasing.

What to Watch for When Replacing the Lens

• Power off before replacing: Always shut down and wait for the cooling fan to stop before removing or installing the lens to avoid static damage to the interface.
• Don't touch the glass: Fingerprints and oils directly affect image quality. Hold the lens barrel without touching the glass. Use an air blower for dust—never wipe with cloth.
• Lock after focusing: After installation, test focus first, then tighten the mounting screws to prevent long-term loosening that could cause image drift.
• Keep interfaces clean: Dust on bayonet and contacts causes poor connection. Clean them when replacing the lens for better reliability.
