Note: Actual imaging performance may be affected by unit condition and installation environment. It is recommended to test one unit before bulk purchase.

What to Watch Out for When Replacing the Lens?

• Power off before replacing the lens: Make sure to shut down and wait for the cooling fan to stop before disassembling or installing the lens to avoid damage to the interface from live operation.
• Don't touch the lens glass: Fingerprints and oil stains will directly affect image quality. Hold the lens barrel, not the glass. If there is dust, use an air blower to gently blow; do not wipe with cloth.
• Focus before tightening: After installation, test the focus first, then tighten the fixing screws to prevent the image from drifting due to loosening during long-term use.
• Pay attention to interface cleanliness: Dust accumulated on the bayonet and contacts may cause poor contact. Clean it while replacing the lens for better reliability.

FAQ

Q: My projector isn't on the list of 8 models above. Can I use WD491?

A: The list shows verified models only, not all compatible units. Projectors of the same brand and generation often share lens interfaces. Send photos of the machine 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 projection optical path, directly determining clarity and color accuracy. Zorsika lenses (models listed in the specifications table above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens elements), with consistent coating工艺. The imaging is sharp with no edge blurring; ordinary replacement lenses typically use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended as the priority choice.

Q: Why choose Zorsika over the OEM?

A: Zorsika lenses are manufactured according to OEM optical specifications, with lens elements, coatings, and throw ratios matched item by item. Each lens undergoes resolution testing before shipment. Compared to OEM products, Zorsika offers shorter delivery times and better overall value; compared to other replacement lenses, optical quality is guaranteed with test data.

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

A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the corresponding throw ratio based on actual installation distance. If you're unsure, send the installation distance and screen dimensions to Zorsika technical support and we'll help you choose.

Q: Is there an installation guide for WD491?

A: Yes. Lens removal and installation procedures for projectors like Appotronics are generally consistent. 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 a 12-month warranty. For normal use and non-human damage (such as impacts, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the shipping invoice date.
