Common Questions
Q: The lens doesn't match the image size. What should I do?
A: First, check the lens mount type and optical axis position of your projector model. Then, select a lens with the appropriate throw ratio based on your actual installation distance. If you're unsure, send us your installation distance and screen size — Zorsika's technical team will help you choose the right lens.
Q: My projector isn't on the list of the 2 models above. Can I still use WK079?
A: The list shows verified models only, not an exhaustive catalog. Projectors from the same brand and generation often share the same lens interface. For better accuracy, take a photo of your projector's nameplate and the original lens, then send it to Zorsika's technical team for confirmation.
Q: Can this lens replace the OEM lens?
A: The lens is the core of the projector's optical system, directly determining image sharpness and color accuracy. Zorsika lenses (models listed in the specifications above) are matched against OEM optical parameters item by item — focal length, throw ratio, and lens elements — with identical coating processes, delivering sharp imaging without soft edges. Ordinary replacement lenses typically use standard glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika lenses are the recommended choice.
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured according to OEM optical specifications, with lens elements, coatings, and throw ratios matched item by item, and each unit undergoes resolution testing before shipping. Compared to OEM, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika provides optical quality backed by actual test data.
Q: What's the warranty period for the lens?
A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the shipping invoice date.
What Zorsika Lenses Deliver

The Zorsika equivalent model is compatible with 2 Vivitek models: RU75953 and RU70983. Enter WK079 in the Zorsika website search system to view the complete compatible model list.
- Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
- Resolution Testing: Each unit tested before shipping, MTF data available
- Coating Process: Lens coating matches OEM grade, minimizing light loss
- Stable Supply: Supports bulk procurement and project fulfillment
In short: The lens is the optical core — don't compromise image quality for a price difference. Zorsika projector lenses are manufactured to OEM specifications, delivering superior overall value.
Note: Actual imaging performance depends on projector condition and installation environment. We recommend requesting a sample unit for testing before bulk procurement.
Lens Replacement Precautions
- Power off before replacing the lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the connectors from live operation.
- Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens by the barrel, not the elements. For dust, use a blower to gently blow — never wipe with cloth.
- Focus before tightening: After positioning the lens, test focus first, then tighten the mounting screws. This prevents image drift from loosening over long-term use.
- Keep the interface clean: Dust on the bayonet mount and contacts can cause poor connection. Clean them when replacing the lens for reliability.
