Zorsika WK091 Projector Lens Compatible Models: Appotronics AL-FU905 AL-FU805 AL-FU705 AL-FU10K

The projector lens directly determines image size and clarity. The WK091 covers 5 Appotronics models—check the list to confirm compatibility before replacing the lens.

Lens Specifications at a Glance

The above specifications come from the Zorsika product database. For the complete technical specification sheet, please contact sales.

WK091 Model Compatibility List (5 models total, with brightness/resolution/zoom ratio)

The following are the verified compatible models for the WK091 (Appotronics 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 chassis interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.

Same Specifications—Why Choose Zorsika

For engineering lenses like the WK091, Zorsika benchmarks each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes—sharp imaging, no blurry edges, ready to use upon installation.

Zorsika's same-spec replacement model is compatible with 5 models including Appotronics AL-FU905, AL-FU805, AL-FU705, AL-FU10K, and AL-FU715; enter WK091 in the query system on the Zorsika official website to find the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
• Resolution Testing: Each unit tested before shipment, with MTF data available
• Coating Process: Lens coatings at the same level as the original, reducing light loss
• Stable Supply: Supports bulk purchasing 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 produced according to original drawings, offering comprehensive advantages.

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

What to Watch Out for When Replacing a Lens

• Power off before replacing 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, test focus first, then tighten the fixing screws, to avoid image drift from loosening during long-term use.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact—cleaning it while replacing the lens is a safer bet.

You May Want to Ask

Q: My machine isn't on the list of 5 models above—can I use the WK091?

A: The list covers verified models, not all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take a photo of the model nameplate and the original lens and send it to Zorsika technical support for confirmation.

Q: Can the lens replace the original 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 the model) benchmark each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes—sharp imaging, no blurry edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

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

Q: What if the lens doesn't match the image size?

A: First confirm the model's lens interface and optical axis position, then choose a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: Does the WK091 come with installation instructions?

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