Why Choose Zorsika
For professional lenses like the WJ12B (Motorized Electric), Zorsika benchmarks each item against original optical parameters (focal length, throw ratio, lens groups), with consistent lens coating technology, delivering sharp images with no edge blur—ready to install and use.
Zorsika's equivalent replacement lens is compatible with 4 models including Quanse Guangxian, Zhongke W10, W9, MU9, and M8; enter WJ12B (Motorized Electric) in the Zorsika official website query system to view the full compatible model list.
- Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original parameters
- Resolution Testing: Each lens individually tested before shipment; MTF data available
- Coating Technology: Lens coating at the same level as the original, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In short: the lens is the optical core—don't gamble image quality for a price difference. Zorsika projector lenses are manufactured to original drawings, offering greater overall value.
Note: Actual imaging performance is affected by projector condition and installation environment; for bulk purchases, we recommend testing one unit first.
FAQ
Q: Why choose Zorsika instead of the original manufacturer?
A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coating, and throw ratio benchmarked item by item, and each lens undergoes resolution testing before shipment. Compared to the original, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.
Q: Can this lens replace the original one?
A: The lens is the core of the projection optical path, directly determining clarity and color. Zorsika lenses (models listed in the specification table above) are benchmarked against original optical parameters (focal length, throw ratio, lens groups) item by item, with consistent lens coating technology, delivering sharp images with no edge blur; ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition scenarios, Zorsika is the recommended choice.
Q: My projector is not in the 4 models listed above. Can I use the WJ12B (Motorized Electric)?
A: The list covers verified models but is not exhaustive. Projectors of the same brand and generation often share the same lens mount. For a safer approach, send photos of the nameplate and original lens to Zorsika technical support for confirmation.
Q: Does the WJ12B (Motorized Electric) come with installation instructions?
A: Yes. The lens removal and installation steps for models like Quanse Guangxian and Zhongke are essentially the same. Contact Zorsika sales to obtain 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; for normal use and non-man-made damage (e.g., impact, water ingress, unauthorized disassembly), please contact after-sales service directly. The warranty period is based on the shipping document date.
Daily Lens Maintenance Tips
- Power off before changing lenses: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with live operation.
- Don't touch the glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel, not the glass; use a blower for dust and never wipe with a dry cloth.
- Lock after focusing: After installation, test focus first, then tighten the locking screws to prevent image drift from loosening over time.
- Keep the interface clean: Dust on the mount and contacts can cause poor connectivity; clean them when changing lenses for added reliability.
