WJ155 Lens Quick Reference: 6 Compatible Projector Models

No need to flip through manuals for lens selection: here's a quick reference for the 6 compatible projector models for the WJ155.

Specifications

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

Compatible Models: 6 Appotronics Projectors (with Brightness, Resolution, and Zoom Ratio)

Below are the verified compatible models for the WJ155 (Appotronics projectors), each with brightness, resolution, and zoom ratio:

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

Why Choose Zorsika for the Same Specifications

The WJ155 is a commonly used lens for commercial projects. Zorsika benchmarks every parameter against the original manufacturer's specifications, and each unit undergoes resolution testing before shipment, ensuring optical quality is backed by data.

Zorsika's equivalent replacement lens is compatible with 6 Appotronics models, including the AL-SH10K, AL-SU10K, AL-SU12K, AL-SU13K, and AL-SU15K. Enter WJ155 in the search system on the Zorsika official website to view the full list of compatible models.

• Optical Benchmarking: Focal length, throw ratio, and lens groups are matched to original manufacturer parameters
• Resolution Testing: Each unit is tested individually before shipment, with MTF data available for review
• Coating Technology: Lens coatings are on par with the original manufacturer, reducing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: the lens is the optical core of a projector—don't gamble image quality for a price difference. Zorsika projector lenses are manufactured to original factory drawings, offering a comprehensive advantage.

Note: Actual imaging performance may vary depending on the projector's condition and installation environment. For bulk purchases, we recommend testing one unit first.

Frequently Asked Questions

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are manufactured according to the original optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit 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 this lens replace the original one?

A: The lens is the core of the projection optical path and directly determines sharpness and color accuracy. Zorsika lenses (models listed 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 images with no edge softness. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately noticeable. For commercial and exhibition applications, Zorsika is the recommended choice.

Q: My projector isn't on the list of 6 models above. Can I use the WJ155?

A: The list covers verified models but is not exhaustive. Projectors of the same brand and generation often share the same lens mount. For a more reliable confirmation, take a photo of the projector's nameplate and original lens and send it to Zorsika technical support.

Q: Is there an installation guide for the WJ155?

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

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use with no signs of physical damage (such as impact, water ingress, or unauthorized disassembly), you can contact our after-sales service directly. The warranty period is based on the date on the shipping document.

Lens Daily Maintenance Tips

• Power off before lens replacement: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with power on.
• Don't touch the glass: Fingerprints and oil can directly affect image quality. Hold the lens by the barrel, not the glass. Use a blower for dust; never wipe with a dry cloth.
• Lock 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 connectivity. Clean them while replacing the lens for extra safety.
