One Table to Understand Zorsika WB381 Projector Lens (Compatible with 1 Model)

When choosing a lens for an engineering projector, first verify the model. The full compatibility list for the WB381 is provided in this article.

Lens Specifications

The above specifications are from the Zorsika product database. For the full technical datasheet, please contact our sales team.

WB381 Compatible Projector Models (1 model, with brightness/resolution/zoom ratio)

The following are verified compatible models for the WB381 (Lansco Kadun projectors), each with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are sourced from the Zorsika product database (refer to the model nameplate/user manual for accuracy); lens compatibility is determined by the body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.

What the Zorsika Lens Offers You

The WB381 is a commonly used lens for projects. Zorsika benchmarks every specification against the original manufacturer's parameters, and each lens undergoes resolution testing before shipment, ensuring optical quality is backed by data.

The Zorsika equivalent replacement lens is compatible with 1 model, including the Lansco Kadun D160UT; enter WB381 in the Zorsika official website search system to view the full compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups are matched to original manufacturer parameters
• Resolution Testing: Each lens is individually tested before shipment, with MTF data available
• Coating Technology: Lens coatings are on par with the original manufacturer, 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 dollars. Zorsika projector lenses are manufactured to original drawings, offering an overall advantage.

Note: Actual imaging performance is affected by projector condition and installation environment. We recommend testing one unit before bulk procurement.

FAQ

Q: Why choose Zorsika instead of the original manufacturer?

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

Q: Can the lens replace the original one?

A: The lens is the core of the projection optical path, directly determining sharpness and color. Zorsika lenses (model listed in the specifications table above) are benchmarked against original optical parameters (focal length, throw ratio, lens groups) item by item, with consistent coating technology, delivering sharp images with no edge softness; ordinary replacement lenses often use standard glass with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: My projector is not in the 1-model list above. Can I use the WB381?

A: The list covers verified models but is not exhaustive. Engineering projectors of the same brand and generation often share the same lens mount. For a safer confirmation, take photos of the nameplate and original lens and send them to Zorsika technical support.

Q: Is there an installation guide for the WB381?

A: Yes. The lens removal and installation steps for models like the Lansco Kadun are essentially the same. Contact Zorsika sales to obtain illustrated or video instructions for the specific model.

Lens Daily 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.
• Don't touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel, not the glass; use a blower for dust and avoid dry wiping with a cloth.
• Tighten after focusing: After installation, test the focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the mount clean: Dust on the bayonet and contacts can cause poor connection; clean them when changing lenses for added safety.
