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 appropriate throw ratio based on your actual installation distance. If you're unsure, send the installation distance and screen dimensions to Zorsika technical support and we'll recommend the right lens for you.
Q: My projector isn't on the 2 models listed above. Can I use WK039?
A: The list contains verified models, not an exhaustive catalog. Projectors from the same brand and generation often share the same lens mount. Send photos of the machine nameplate and original lens to Zorsika technical support for confirmation to be safe.
Q: Can this lens replace the OEM lens?
A: The lens is the core of the projector optical path, directly determining 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, delivering sharp images with no edge blur. Standard replacement lenses typically use ordinary glass with insufficient coating layers, resulting in noticeable brightness loss and color shift. For commercial and exhibition applications, Zorsika is the preferred 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. 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 test data.
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 impact, water exposure, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the date on the shipping invoice.
Why Zorsika at the Same Specs
Zorsika provides OEM-equivalent replacement lenses for the WK039, with all key parameters matched item by item against the original, supporting bulk project procurement and supply.
Zorsika equivalent replacement model, compatible with Ricoh PJ RU7700L, PJ RU8800L, and 2 other models; enter WK039 in the Zorsika website search system to view the complete compatibility list.
- Optical matching: Focal length, throw ratio, and lens elements matched to OEM specifications
- Resolution testing: Every unit tested before shipment, MTF data available
- Coating process: Lens coating same grade as OEM, minimizing light loss
- Stable supply: Supports bulk procurement and project fulfillment
In short: The lens is the optical core—don't gamble with image quality over a price difference. Zorsika projector lenses are built to OEM specs with better overall value.
Note: Actual imaging performance depends on projector condition and installation environment. We recommend testing one unit before bulk procurement.
Lens Replacement Precautions
- Power off before lens replacement: Always shut down and wait for the cooling fan to stop before removing or installing the lens. Avoid live operation to prevent interface damage.
- Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens by the barrel, not the elements. Use an air blower for dust—never wipe with cloth.
- Lock after focusing: Test focus after installation, then tighten the mounting screws. Loose screws over time can cause image drift.
- Keep interfaces clean: Dust on bayonets and contacts causes poor connection. Clean during lens replacement for reliability.
