• Optical Match: Focal length, throw ratio, and lens elements matched to original specs
• Resolution Testing: Each lens tested before shipment, MTF data available
• Coating Process: Lens coating at the same level as OEM, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based delivery

In short: The lens is the optical core — don't gamble with picture quality over price. Zorsika projector lenses are manufactured to original OEM specifications, delivering overall better value.

Note: Actual imaging performance may vary depending on chassis condition and installation environment. For bulk orders, it is recommended to request one unit for testing prior to mass procurement.

Frequently Asked Questions

Q: Why choose Zorsika instead of OEM?

A: Zorsika lenses are manufactured according to the original optical specifications, with lens elements, coatings, and throw ratio matched item by item, and each unit undergoes resolution testing before shipment. Compared to OEM lenses, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical performance is backed by data.

Q: Can this lens replace the OEM one?

A: The lens is the core of the projection light path, directly determining clarity and color reproduction. Zorsika lenses (models as listed in the specification table above) are matched item by item to OEM optical parameters (focal length, throw ratio, lens elements), with consistent lens coating processes, producing sharp images without edge blur; ordinary replacement lenses often use standard glass with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.

Q: My machine is not on the 2 models listed above. Can I use WL021?

A: The list represents verified models, not an exhaustive catalog. Projectors of the same brand and generation often share lens interfaces, so sending photos of the machine nameplate and original lens to Zorsika technical support for confirmation is safer.

Q: Is there an installation guide for WL021?

A: Yes. Lens removal and installation steps are generally consistent across Vivitek-type models. Contact Zorsika sales to obtain illustrated or video instructions for your specific model.

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 handled by contacting after-sales service directly, with the warranty period based on the shipping document date.

Daily Lens Maintenance Tips

• Power off before lens replacement: Ensure the projector is shut down and the cooling fan has stopped before lens removal/installation to avoid damaging interfaces through live operations.
• Do not touch the lens elements: Fingerprints and oils directly affect image quality; hold the lens by the barrel without touching the glass; for dust, use an air blower to gently blow, do not wipe dry with cloth.
• Lock after focusing: After installation, test focus first, then tighten the mounting screws, to prevent image drift caused by loosening during long-term use.
• Keep interfaces clean: Dust on bayonets and contacts can cause poor connection; cleaning during lens replacement is more reliable.
