Compatible Models: 3 ViewSonic Projectors (with Brightness, Resolution, Zoom Ratio)

The following are verified compatible models for the WK161 (ViewSonic projectors), with brightness, resolution, and zoom ratio listed for each:

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

What Zorsika Lenses Offer You

The WK161 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 for the same specifications is compatible with 3 models including the ViewSonic LS860WU+, LS921WU, and LS920WU; enter WK161 in the query system on the Zorsika official website 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 level as the original factory, reducing light loss
• Stable Supply: Supports bulk purchasing and project supply

In one sentence: 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 and offer comprehensive advantages.

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

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 guaranteed with data.

Q: Can the lens replace the original factory one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers as shown 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 lenses with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition scenarios, Zorsika is recommended as the priority.

Q: My projector is not among the 3 models listed above — can I use the WK161?

A: The list covers verified models but does not represent all. Engineering projectors of the same brand and generation often share the same lens interface. It is more reliable to take photos of the body nameplate and original lens and send them to Zorsika technical support for confirmation.

Q: Does the WK161 come with installation instructions?

A: Yes. The lens removal and installation steps for ViewSonic models of this type are basically the same. Contact Zorsika sales to obtain illustrated or video instructions for the corresponding 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: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop to avoid damaging the interface by operating with power on.
• Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust — do not wipe dry with a cloth.
• Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws to avoid image drift from loosening during long-term use.
• Keep the interface clean: Dust accumulation on the mount and contacts can cause poor contact. Cleaning them while changing the lens is a safer practice.
