Zorsika WK261 Projector Lens Compatible Models (2 Models)

WK261 is a lens compatible with engineering projectors from brands such as Appotronics. This article compiles its 2 compatible projector models and selection precautions.

Lens Specifications

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

Compatibility: List of 2 Models (with Specifications)

The following are verified compatible models for WK261 (Appotronics projectors), each with brightness, resolution, and zoom ratio:

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

What Zorsika Lenses Offer You

For engineering lenses like WK261, Zorsika benchmarks each item against original optical parameters (focal length, throw ratio, lens groups), with consistent lens coating technology, delivering sharp imaging with no edge blur — ready to install and use.

Zorsika replacement lens with equivalent specifications, compatible with 2 models including Appotronics AL-DF765 and AL-DF767; enter WK261 in the Zorsika official website query system to view the full compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original parameters
• Resolution Testing: Each unit individually tested before shipment; MTF data available
• Coating Technology: Lens coating at the same grade as original, reducing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: The lens is the optical core — don't gamble picture quality for a price difference. Zorsika projector lenses are manufactured to original drawings, offering overall advantages.

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

What to Watch Out For When Replacing the Lens?

• Power off before replacing 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 from live operation.
• Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens barrel, not the glass; use an air blower for dust, never wipe with a dry cloth.
• Focus before tightening: After installation, test focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the interface clean: Dust on the mount and contacts can cause poor connectivity; clean them while replacing the lens for peace of mind.

Frequently Asked Questions

Q: My projector isn't in the 2 models listed above. Can I use WK261?

A: The list covers verified models only, not all possibilities. Engineering projectors of the same brand and generation often share the same lens mount. For a definitive answer, send a photo of the nameplate and original lens to Zorsika technical support.

Q: Can this lens replace the original one?

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

Q: Why choose Zorsika instead of the original?

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

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

A: First confirm the lens mount and optical axis position of your projector model, then select a lens with the appropriate throw ratio based on your actual installation distance. If you're unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: Is there an installation guide for WK261?

A: Yes. The lens removal and installation steps for Appotronics models like these are essentially the same. Contact Zorsika sales to get illustrated or video instructions for your specific model.
