Frequently Asked Questions
Q: What if the lens doesn't match the screen size?
A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the corresponding throw ratio based on the actual installation distance; if you're unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you with recommendations.
Q: My machine is not on the list of 1 model above, can I use the WJ12D (Electric)?
A: The list shows verified models, not all possible ones. Projectors of the same brand and generation often share lens interfaces. Send photos of the machine nameplate and original lens to Zorsika technical support for confirmation to be safe.
Q: Can the lens replace the OEM one?
A: The lens is the core of the projection optical path, directly determining clarity and color. Zorsika lenses (models as listed in the specifications table above) are matched item-by-item against the original manufacturer's optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, providing sharp imaging without edge softening; ordinary replacement lenses often use standard glass lenses with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended as the priority choice.
Q: Why choose Zorsika over the OEM?
A: Zorsika lenses are manufactured according to the original manufacturer's optical specifications, with lens groups, coatings, and throw ratios matched item-by-item. Each unit undergoes resolution testing before shipping. Compared to OEM options, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, optical quality is guaranteed with 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 impacts, water ingress, unauthorized disassembly) can be handled directly through after-sales service, with the warranty period based on the shipping document date.
Why Choose Zorsika

The Zorsika OEM-spec replacement model is compatible with 1 model including the Daheng DU16K; enter WJ12D (Electric) in the Zorsika official website query system to find the complete compatible model list.
- Optical Matching: Focal length, throw ratio, and lens group are matched according to OEM parameters
- Resolution Testing: Each unit tested before shipping, MTF data available
- Coating Process: Lens coating at the same level as OEM, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
Bottom line: The lens is the optical core—don't gamble with image quality over price differences. Zorsika projector lenses are manufactured according to OEM optical drawings, providing better overall value.
Note: Actual imaging performance is affected by machine condition and installation environment. It is recommended to test one unit before bulk procurement.
What to Watch for When Replacing the Lens?
- Power off before lens replacement: Be sure to shut down and wait for the cooling fan to stop before installing or removing the lens to avoid interface damage from live operations.
- Don't touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel and avoid touching the glass; use an air blower to gently blow away dust, do not wipe dry with cloth.
- Lock tight after focusing: After the lens is in place, test focus first, then lock the fixing screws to avoid image drift caused by loosening during long-term use.
- Pay attention to interface cleanliness: Dust buildup on mounts and contacts can cause poor contact; clean them during lens replacement for added safety.
