Why Choose Zorsika at the Same Specifications

Zorsika offers factory-grade replacement lenses for WD621 with matching key parameters, supporting bulk procurement and project supply.

Zorsika's equivalent replacement model is compatible with InFocus KP850, KU900, and 2 other models; enter WD621 in the Zorsika website search system to find the complete compatible model list.

• Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
• Resolution Testing: Every unit tested before shipment, MTF data available
• Coating Process: Lens coating at OEM-grade level, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based delivery

Bottom line: The lens is the optical core—don't compromise image quality for price difference. Zorsika projector lenses are manufactured to OEM specifications, offering overall advantages.

Note: Actual imaging performance may vary depending on chassis condition and installation environment. It is recommended to test one unit before bulk procurement.

What to Watch Out for When Replacing a Lens?

• Power Off Before Replacing Lens: Always power off and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the connectors with live operation.
• Don't Touch the Glass: Fingerprints and oils directly affect image quality. Hold the lens barrel, not the glass. Use an air blower for dust—never wipe with dry cloth.
• Lock After Focusing: After proper installation, test focus first, then tighten the mounting screws to prevent loosening and image drift over long-term use.
• Check Connector Cleanliness: Dust buildup on the mount and contacts can cause poor connection—clean them while replacing the lens for better reliability.

FAQ

Q: My machine isn't on either of the two lists above. Can I use the WD621?

A: The lists show verified models only, not all compatible units. Projectors from 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 sharpness and color accuracy. Zorsika lenses (models listed in the specs above) are matched item-by-item against OEM optical parameters (focal length, throw ratio, lens elements), with consistent coating工艺, delivering sharp imaging without soft edges. Generic replacement lenses typically use ordinary glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to OEM optical blueprints, matched item-by-item for lens elements, coatings, and throw ratio, with each unit undergoing resolution testing before shipment. Compared to OEM, we offer shorter lead times and better overall value; compared to other replacement lenses, we provide guaranteed optical performance with data to back it up.

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

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

Q: Is there an installation guide for the WD621?

A: Yes. Lens removal and installation procedures are essentially consistent across InFocus models. Contact Zorsika sales for 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-induced damage (such as impacts, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the invoice date.
