What Zorsika Lenses Offer You

The WB373 is a commonly used lens for projects. Zorsika benchmarks each parameter against the original factory specifications, performs resolution testing on every unit before shipment, and guarantees optical quality with data.

Zorsika's equivalent replacement model, compatible with Optoma ZK1320, ZK1120, CKL1300T, CKL1100T, MSV9143, and other 6 models; enter WB373 in the Zorsika official website query system to find 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, MTF data available
  • Coating Process: Lens coatings at the same level as the original factory, reducing light loss
  • Stable Supply: Supports bulk purchasing and project supply

In a nutshell: the lens is the optical core — don't gamble on image quality to save a few bucks. Zorsika projector lenses are manufactured according to original factory drawings, offering comprehensive advantages.

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

You May Want to Ask

Q: Why choose Zorsika instead of the original factory?

A: Zorsika lenses are manufactured according to original factory optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and every unit undergoes resolution testing before shipment. Compared to the original factory, delivery times are shorter and 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 (see the specification table above for models) 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 blurry 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 machine isn't on the 6-model list above — can I use the WB373?

A: The list covers verified models but doesn't represent all. Same-brand, same-generation engineering projectors often share lens interfaces. It's safer to send a photo of the body nameplate and original lens to Zorsika technical support for confirmation.

Q: Does the WB373 come with installation instructions?

A: Yes. The lens removal and installation steps for Optoma models like these 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 damage (such as impacts, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipping document.

Daily Lens Maintenance Tips

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