What Zorsika Lenses Offer You

The WB381 is a commonly used lens for projects. Zorsika benchmarks each parameter against the original factory specifications, and every unit undergoes resolution testing before shipment, ensuring optical quality backed by data.

Zorsika's equivalent replacement model, compatible with the Lansheng Katon D160UT and 1 other model; enter WB381 in the Zorsika official website query system to view the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original factory parameters
• Resolution Testing: Every unit tested before shipment, with traceable MTF data
• Coating Process: Lens coatings at the same grade 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 on image quality to save a few bucks. Zorsika projector lenses are manufactured to original factory drawings, offering a comprehensive advantage.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing first.

Frequently Asked Questions

Q: Why choose Zorsika instead of the original factory?

A: Zorsika lenses are manufactured to original factory optical drawings, with lens groups, coatings, and throw ratio benchmarked item by item, and every unit undergoes resolution testing before shipment. Compared to the original factory, lead times are shorter and the overall value is better; compared to other replacement lenses, optical quality is backed by data.

Q: Can the lens replace the original factory one?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (models listed in the specification table above) are benchmarked item by item against original factory optical parameters (focal length, throw ratio, lens groups), with consistent lens coating processes, delivering sharp imaging with no blurring at the edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: My projector isn't on the list of 1 model above — can I use the WB381?

A: The list covers verified models, not all of them. Same-brand, same-generation engineering projectors often share the same lens interface. It's safer to send photos of the body nameplate and the original lens to Zorsika technical support for confirmation.

Q: Does the WB381 come with installation instructions?

A: Yes. The lens removal and installation steps for Lansheng Katon models like this are basically the same. Contact Zorsika sales for illustrated or video instructions for your specific model.

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 impact, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.

Daily Lens Maintenance Tips

• Power off before changing the lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface while powered on.
• Don't touch the lens elements: Fingerprints and oil smudges directly affect image quality. Hold the lens by the barrel, not the glass. For dust, use an air blower gently — don't wipe dry with a cloth.
• Focus before tightening: After installing the lens in place, test the focus first, then tighten the fixing screws to avoid image drift from loosening over time.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor connections. Cleaning them while changing the lens is a good habit.
