What Zorsika Lenses Offer You
WK038 is a commonly used lens for projects. Zorsika matches each original factory parameter item by item, and every unit undergoes resolution testing before shipment, ensuring optical performance backed by data.
Zorsika's equivalent replacement model is compatible with 4 Optoma and Hualu models: ZU850, ZU1050, ZU105P, and ZU1300. Enter WK038 in the query system on Zorsika's official website to find the complete compatibility list.
- Optical Benchmarking: Focal length, throw ratio, and lens elements are matched to original factory specifications
- Resolution Testing: Every unit is tested before shipment, with MTF data available for reference
- Coating Process: Lens coatings match original factory grade, minimizing light loss
- Stable Supply: Supports bulk purchasing and project-based orders
One-line summary: The lens is the optical core—don't gamble with image quality over price differences. Zorsika projector lenses are manufactured according to original factory drawings, offering comprehensive advantages.
Note: Actual imaging performance may vary based on projector condition and installation environment. For bulk orders, it is recommended to test one unit first.
What to Watch for When Replacing a Lens
- Power off before replacing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens. Avoid working on a powered-on unit to prevent interface damage.
- Don't touch the glass: Fingerprints and oils directly affect image quality. Hold the lens barrel without touching the glass. Use an air blower to gently remove dust—do not wipe with cloth.
- Focus before tightening: After positioning, test the focus, then tighten the mounting screws. This prevents image drift from loosening over time.
- Keep the interface clean: Dust on the mount and contacts causes poor connectivity. Clean them while replacing the lens for added reliability.
Common Questions
Q: My model isn't on the 4-model list above. Can I use WK038?
A: The list represents verified models only, not the full range. Projectors from the same brand and generation often share lens interfaces. Send photos of the projector nameplate and the original lens to Zorsika Technical Support for confirmation.
Q: Can this lens replace the OEM lens?
A: The lens is the core of the projector's optical path, directly determining sharpness and color accuracy. Zorsika lenses (models listed in the spec table above) are benchmarked against OEM optical parameters—focal length, throw ratio, and lens elements—item by item, with consistent coating processes that deliver sharp images without soft edges. Ordinary replacement lenses typically use standard glass with insufficient coating layers, resulting in visible brightness loss and color shift. For commercial and exhibition applications, Zorsika is the recommended choice.
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured according to original factory optical drawings, with lens elements, coatings, and throw ratios matched item by item, and every unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika provides optical performance backed by data.
Q: The lens doesn't fit my screen size. What should I do?
A: First verify the 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: Is there an installation guide for WK038?
A: Yes. Lens removal and installation procedures are essentially the same for Optoma and Hualu models. Contact Zorsika Sales to receive 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. Normal use and non-human-induced damage (such as drops, water exposure, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the shipping document date.
