What Zorsika Lenses Bring to You

WE289 is a commonly used lens in projector installations. Zorsika matches each specification against the original manufacturer's parameters, and every unit undergoes resolution testing before leaving the factory, ensuring guaranteed optical performance.

Zorsika's equivalent replacement model is compatible with 2 Vivitek models including RU75953 and RU70983. Enter WE289 in the query system on Zorsika's official website to find the complete list of compatible projector models.

• Optical Matching: Focal length, throw ratio, and lens elements matched to original manufacturer specifications
• Resolution Testing: Individual unit testing before shipment, MTF data available for review
• Coating Process: Lens coating at the same level as original, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based orders

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

Note: Actual imaging performance may vary depending on machine condition and installation environment. We recommend ordering one unit for testing prior to bulk purchase.

What to Watch for When Replacing a Lens?

• Power off first: Always shut down and wait for the cooling fan to stop before removing or installing a lens to avoid electrostatic damage to connectors.
• Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens by the barrel without touching the elements; use an air blower for dust, never wipe with cloth.
• Lock after focusing: Focus and test after proper installation, then tighten the mounting screws to prevent loosening that could cause image drift over time.
• Check connector cleanliness: Dust on bayonet mounts and contacts can cause poor connection—clean them when replacing the lens for better reliability.

Frequently Asked Questions

Q: My machine isn't on the list of 2 models. Can I use WE289?

A: The list represents verified models only, not all possible ones. 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 original manufacturer's lens?

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

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are manufactured according to original optical blueprints with item-by-item matching of lens elements, coating, and throw ratio. Every unit undergoes resolution testing before shipment. Compared to OEM lenses, we offer shorter lead times and better overall value; compared to other replacement lenses, we provide measurable optical performance.

Q: The lens doesn't match the screen size. What should I do?

A: First verify the machine's lens interface and optical axis position, then select a lens with the appropriate 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 WE289?

A: Yes. Lens removal and installation procedures are essentially the same for Vivitek models of this type. Contact Zorsika sales to receive illustrated or video guides for your specific model.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly) can be directly handled through after-sales service. Warranty period is calculated from the date on the shipping invoice.
