• Coating Process: Lens coatings at the same level as OEM, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based supply

Bottom line: The lens is the optical core—don't gamble with picture quality over price differences. Zorsika projector lenses are manufactured to original factory specifications, offering comprehensive advantages.

Note: Actual imaging performance depends on chassis condition and installation environment; it is recommended to test one unit before bulk procurement.

Frequently Asked Questions

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to OEM optical specifications, with lens groups, coatings, and throw ratio individually matched. Shorter lead times and better overall value compared to OEM; optical quality backed by data compared to other alternative lenses.

Q: Can the lens replace the OEM one?

A: The lens is the core of the projection optical path, directly determining clarity and color. Zorsika lenses (models listed in the specifications table above) are individually matched against OEM optical parameters (focal length, throw ratio, lens group), with identical lens coating processes, delivering sharp imaging with no edge blurring. Ordinary replacement lenses often use regular glass lenses with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.

Q: My machine isn't on the 8-model list above. Can I use the WD501?

A: The list represents verified models, not an exhaustive inventory. Projectors from the same brand and generation often share lens interfaces. Take a photo of the machine nameplate and the original lens and send it to Zorsika technical support for confirmation.

Q: Does the WD501 come with installation instructions?

A: Yes. Lens removal and installation steps are largely consistent for machines like Bijie Networks/Huokesi. Contact Zorsika sales for illustrated or video instructions specific to your model.

Q: What is the lens warranty period?

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

Lens Routine Maintenance Tips

• Disconnect power before changing lenses: Always power off and wait for the cooling fan to stop before removing or installing the lens to avoid interface damage from live operations.
• Do not touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel when handling; do not touch the glass. Use an air blower to gently remove dust—do not wipe with cloth.
• Lock after focusing: After the lens is properly seated, test the focus, then tighten the mounting screws. This prevents image drift caused by loosening over time.
• Keep interfaces clean: Dust on the mount and contacts can cause poor connection. Clean them when replacing the lens for reliability.
