Zorsika equivalent replacement model, compatible with Kemai UEC-WU135 and 1 other model; enter WB03D in the search system on the Zorsika official website to view the complete compatible model list.
- Optical Benchmarking: Focal length, throw ratio, and lens elements matched to OEM specifications
- Resolution Testing: Each unit tested before shipment, MTF data available for review
- Coating Process: Lens coating at the same level as OEM, minimizing light loss
- Stable Supply: Supporting bulk procurement and project supply
In short: The lens is the optical core—don't gamble with picture quality over price differences. Zorsika projector lenses are manufactured to OEM specifications, offering overall better value.
Note: Actual imaging performance is affected by chassis condition and installation environment. It is recommended to obtain one unit for testing before bulk procurement.
What to Watch Out for When Replacing the Lens?
- Power off before replacing the lens: Always turn off the projector and wait for the cooling fan to stop completely before removing or installing the lens. Avoid working with the power on to prevent interface damage.
- Don't touch the glass elements: Fingerprints and oil stains will directly affect image quality. Hold the lens by the barrel, not the glass. Use an air blower to gently remove dust; do not wipe with a dry cloth.
- Focus before tightening: After proper installation, test the focus first, then tighten the mounting screws. This prevents image shift caused by loosening over extended use.
- Keep the interface clean: Dust accumulation on the mount and contacts can cause poor connection. Clean them while replacing the lens for added peace of mind.
Frequently Asked Questions
Q: My projector isn't on the compatibility list. Can I use the WB03D?
A: The list shows verified models only, not all compatible units. Projectors from the same brand and generation often share the same lens interface. Send photos of your machine's nameplate and original lens to Zorsika technical support for confirmation.
Q: Can the lens replace the original OEM lens?
A: The lens is the core of the projector's optical path, directly determining clarity and color accuracy. Zorsika lenses (models listed in the specs above) are matched item by item against OEM optical parameters—focal length, throw ratio, and lens elements—with consistent lens coating processes, delivering sharp images without edge softening. Generic replacement lenses typically use ordinary glass with fewer 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 the OEM?
A: Zorsika lenses are manufactured according to OEM optical specifications, with lens elements, coatings, and throw ratios matched item by item. Every unit undergoes resolution testing before shipment. Compared to OEM options, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, optical quality is backed by test data.
Q: The lens doesn't match my screen size. What should I do?
A: First confirm your projector'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: Does the WB03D come with installation instructions?
A: Yes. Lens removal and installation procedures are essentially the same for projectors like Kaimai. Contact Zorsika sales to receive illustrated or video instructions for your specific model.
Q: What is the warranty period for the lens?
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 handled through after-sales service. The warranty period is calculated from the invoice date.
