Frequently Asked Questions

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to original optical blueprints, with lens elements, coatings, and throw ratios matched item by item, and each unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, optical quality is backed by data.

Q: Can the lens replace the original?

A: The lens is the core of the projector light path, directly determining sharpness and color. Zorsika lenses (models listed in the spec table above) are matched item by item to original optical parameters (focal length, throw ratio, lens elements), with consistent lens coating process, delivering sharp images without edge blurring; ordinary replacement lenses often use regular glass elements with insufficient coating layers, resulting in noticeable brightness loss and color deviation. For engineering and exhibition applications, Zorsika is the preferred choice.

Q: My machine is not on the 8-model list above. Can I use SA13+?

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

Q: Does SA13+ come with installation instructions?

A: Yes. Lens removal and installation procedures are essentially consistent across Appotronics models. Contact Zorsika sales to receive illustrated or video instructions for your specific model.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with 12 months of warranty. For normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly), contact after-sales service directly. Warranty period is calculated from the shipping document date.

Lens Daily Maintenance Tips

• Power off before lens replacement: Always shut down and wait for the cooling fan to stop before removing or installing the lens to avoid interface damage from live operation.
• Do not touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens barrel, not the elements; use an air blower for dust, not a dry cloth.
• Focus before tightening: After positioning, test focus first, then tighten the mounting screws to prevent image drift from loosening during prolonged use.
• Keep interfaces clean: Dust on bayonets and contacts can cause poor connection. Clean during lens replacement for added reliability.
