Frequently Asked Questions
Q: What should I do if the lens doesn't match the picture size?
A: First confirm the model'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 size to Zorsika technical support, and we'll help you choose.
Q: My projector isn't on the list of 1 compatible model above — can I use the WJ12V?
A: The list covers verified models only and is not exhaustive. Engineering projectors of the same brand and generation often share the same lens interface. To be safe, send photos of the body nameplate and the original lens to Zorsika technical support for confirmation.
Q: Can this lens replace the original factory lens?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers as shown in the specification table above) are benchmarked item by item against the original factory optical parameters (focal length, throw ratio, lens groups), with consistent lens coating processes — delivering sharp imaging with no edge blurring. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition applications, Zorsika is recommended.
Q: Why choose Zorsika instead of the original factory?
A: Zorsika lenses are manufactured according to the original factory optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared with the original factory, lead times are shorter and overall value is better; compared with other replacement lenses, optical quality is backed by data.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human-caused damage (such as impacts, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipment document.
Why Choose Zorsika
For engineering lenses like the WJ12V, Zorsika benchmarks item by item against the original factory optical parameters (focal length, throw ratio, lens groups), with consistent lens coating processes — delivering sharp imaging with no edge blurring, ready to use right out of the box.
Zorsika's equivalent replacement model is compatible with the Koyingda C-WU800L and 1 other model; enter WJ12V in the query system on the Zorsika official website to view the complete compatible model list.
- Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original factory parameters
- Resolution Testing: Each unit tested before shipment, with traceable MTF data
- Coating Process: Lens coatings at the same level as the original factory, reducing light loss
- Stable Supply: Supports bulk purchasing and project supply
In short: the lens is the optical core — don't gamble on picture quality to save a few dollars. Zorsika projector lenses are manufactured according to original factory drawings and offer superior overall value.
Note: Actual imaging performance depends on the projector's condition and installation environment. Before bulk purchasing, we recommend obtaining 1 unit for hands-on testing.
What to Watch Out for When Changing Lenses
- Power off before changing the lens: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop to avoid damaging the interface while powered on.
- Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass. For dust, use an air blower gently — do not wipe dry with a cloth.
- Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws to prevent image drift from loosening during long-term use.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while changing the lens is a safer practice.
