Frequently Asked Questions
Q: What if the lens doesn't match the screen size?
A: First confirm the lens mount and optical axis position of your projector model, then select a lens with the matching throw ratio based on the actual installation distance. If you're unsure, send the installation distance and screen dimensions to Zorsika Technical Support and we'll recommend the right option.
Q: My model isn't on the list of 5 models above. Can I use WK175?
A: The list represents verified models only, not an exhaustive catalog. Projectors from the same brand and generation often share lens mounts. 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 and directly determines clarity and color accuracy. Zorsika lenses (models listed in the specifications above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens elements), with identical coating processes, producing sharp images without edge blur. Ordinary replacement lenses typically use regular 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, with lens elements, coatings, and throw ratios matched item by item. Every unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, optical performance is backed by data.
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, unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the invoice date.
Why Recommend Zorsika at the Same Specifications
Zorsika provides OEM-equivalent replacement lenses for WK175, with all key parameters matched item by item to the original, supporting bulk project procurement and supply.
Zorsika equivalent replacement model, compatible with Hulu HL-KU650, HL-KU730, HL-B650U, HL-Z600U, HL-Z550U and other 5 models; enter WK175 in the Zorsika website search system to view the complete model compatibility list.
- Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
- Resolution Testing: Individual unit testing before shipment, MTF data available
- Coating Process: Lens coating at OEM grade, minimizing light loss
- Stable Supply: Supports bulk procurement and project fulfillment
Bottom line: The lens is the optical core—don't compromise image quality for a price difference. Zorsika projector lenses are manufactured according to OEM blueprints with overall better advantages.
Note: Actual imaging performance depends on the projector condition and installation environment. We recommend testing one unit before bulk procurement.
What to Watch for When Replacing the Lens
- Power off before lens replacement: Always shut down and wait for the cooling fan to stop completely before removing or installing the lens to avoid damaging the interface with live current.
- Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel, not the glass. Use an air blower for dust—never wipe with cloth.
- Focus before tightening: Test focus after proper installation, then secure the mounting screws. Loose screws over time can cause image drift.
- Keep the interface clean: Dust on the bayonet mount and contacts can cause poor connection. Clean during lens replacement for better reliability.
