• Optical alignment: Focal length, throw ratio, and lens group matched to original parameters
• Resolution testing: Every unit tested before shipment, MTF data available
• Coating process: Lens coating at the same level as original, reducing light loss
• Stable supply: Supports bulk procurement and project orders

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

Note: Actual imaging performance is affected by machine 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 original optical drawings, with lens group, coating, and throw ratio aligned item by item, and resolution tested for every unit before shipment. Compared to OEM, Zorsika offers shorter lead time and better overall value; compared to other alternative lenses, optical quality is guaranteed with data.

Q: Can the lens replace the OEM one?

A: The lens is the core of the projection light path, directly determining clarity and color. Zorsika lenses (models as listed in the specification table above) are aligned item by item with original optical parameters (focal length, throw ratio, lens group), with consistent lens coating process, sharp imaging and no edge blurring; ordinary alternative lenses often use regular glass lenses with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: My machine is not on the 33-model list above. Can I use SA18+?

A: The list shows verified models, not all models. Engineering machines of the same brand and generation often share lens interfaces. It is safer to take photos of the machine nameplate and original lens and send them to Zorsika technical support for confirmation.

Q: Is there an installation guide for SA18+?

A: Yes. The lens removal and installation steps are basically the same for Hocsor, Yunguo, NEC and similar models. Contact Zorsika sales to get the illustrated or video instructions for the corresponding model.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with 12 months warranty; normal use and non-human damage (such as impact, water ingress, unauthorized disassembly) can be directly handled through after-sales service. The warranty period is based on the shipping document date.

Lens Routine Maintenance Tips

• Disconnect power before replacing lens: Make sure to power off 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: Fingerprints and oil stains directly affect picture quality. Hold the lens barrel without touching the glass; use an air blower to gently blow away dust, do not wipe with cloth.
• Lock tight after focusing: After installing in place, test focus first, then lock the fixing screws to avoid image drift caused by loosening during long-term use.
• Keep interface clean: Dust accumulation on bayonet and contacts can cause poor contact. Clean it when replacing the lens for better reliability.
