Why Choose Zorsika

Zorsika offers replacement lenses for the WD491 with identical specifications to the original, with every key parameter matched against the OEM part, supporting bulk project procurement and supply.

Zorsika replacement lens with matching specifications, compatible with 8 Appotronics models including AL-DH560, AL-DH660, AL-DH760, AL-DH860, AL-DU635, etc. Enter WD491 in the Zorsika official website query system to view the full compatibility list.

• Optical Matching: Focal length, throw ratio, and lens groups are matched to OEM parameters
• Resolution Testing: Each lens is individually tested before shipment; MTF data available upon request
• Coating Process: Lens coatings are on par with OEM quality, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: the lens is the optical core — don't gamble image quality for a price difference. Zorsika projector lenses are manufactured to OEM drawings, offering an overall better value.

Note: Actual imaging performance is affected by projector condition and installation environment. We recommend testing one unit before bulk procurement.

What to Keep in Mind When Replacing the Lens

• Power off before replacing the lens: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface.
• Don't touch the glass: Fingerprints and oil can directly affect image quality. Hold the lens barrel, not the glass. Use a blower for dust; never wipe with a dry cloth.
• Lock after focusing: Focus and test after installation, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the interface clean: Dust on the mount and contacts can cause poor connectivity. Clean them while replacing the lens.

Frequently Asked Questions

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

A: The list covers verified models but isn't exhaustive. Projectors from the same brand and generation often share the same lens mount. Send a photo of the model plate and the original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the OEM one?

A: The lens is the core of the projection optical path and directly determines clarity and color. Zorsika lenses (model shown in the spec table above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens groups), with identical coating processes, delivering sharp images with no soft edges. Ordinary replacement lenses often use standard glass with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika instead of the OEM?

A: Zorsika lenses are manufactured to OEM optical drawings, with lens groups, coatings, and throw ratio matched item by item, and 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 data.

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

A: First verify the lens mount and optical axis position of your projector, then select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: Is there an installation guide for the WD491?

A: Yes. The lens removal and installation steps for Appotronics models are largely the same. Contact Zorsika sales to get illustrated or video instructions for your specific model.
