Frequently Asked Questions

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

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

Q: My machine isn't on the 1-model list above. Can I use LA021?

A: The list represents verified models only, not an exhaustive catalog. Same-brand, same-generation engineering projectors often share lens interfaces. For more reliability, send photos of your chassis nameplate and original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the OEM lens?

A: The lens is the core of the projector's optical path and directly determines clarity and color accuracy. Zorsika lenses (models shown in the specification table above) are matched item-by-item against OEM optical parameters (focal length, throw ratio, lens assembly), with consistent coating processes—delivering sharp imaging without edge blurring. Common replacement lenses often use standard glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the preferred choice.

Q: Why choose Zorsika over the OEM?

A: Zorsika lenses are manufactured according to OEM optical specifications, with lens assemblies, coatings, and throw ratios matched item-by-item. Each lens 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 test data.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use without human damage (such as impact, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the date on the shipping invoice.

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

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

Note: Actual imaging performance is affected by projector condition and installation environment; it is recommended to test one unit before bulk procurement.

What to Watch for When Replacing the Lens

• Power off before replacing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damage from live operation.
• Do not touch the optical elements: Fingerprints and oils directly affect image quality; hold the lens barrel without touching the glass; use an air blower for dust, do not wipe with cloth.
• Lock after focusing: Test focus after installation, then tighten the mounting screws to prevent image drift from loosening over time.
• Pay attention to interface cleanliness: Dust on the mount and contacts can cause poor connection; clean them during lens replacement for better reliability.
