Same Specifications — Why Choose Zorsika
Zorsika offers an OEM-equivalent replacement lens for the WK099 (<18K Lumens), with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika's equivalent-spec replacement model is compatible with 6 projector models including Appotronics AL-SH10K, AL-SU10K, AL-SU12K, AL-SU13K, and AL-SU15K; enter WK099 (<18K Lumens) in the Zorsika official website query system to view the complete model compatibility list.
- Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original parameters
- Resolution Testing: Each unit tested before shipment, with MTF data available
- Coating Process: Lens coatings at the same grade as the original, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In short: the lens is the optical core — don't gamble on image quality to save a few dollars. Zorsika projector lenses are manufactured to original drawings and offer a comprehensive advantage.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing.
Frequently Asked Questions
Q: Why choose Zorsika instead of the original manufacturer?
A: Zorsika lenses are manufactured to original optical drawings, with lens groups, 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: Can the lens replace the original?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers in the specification table above) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens groups), with consistent lens coating processes, delivering sharp imaging with no soft edges; 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 recommended.
Q: My projector isn't in the list of 6 above — can I use the WK099 (<18K Lumens)?
A: The list covers verified models, not all models. Same-brand, same-generation engineering projectors often share lens interfaces. It's safer to send a photo of the projector nameplate and original lens to Zorsika technical support for confirmation.
Q: Does the WK099 (<18K Lumens) come with installation instructions?
A: Yes. The lens removal and installation steps for Appotronics projectors of this type are essentially the same. Contact Zorsika sales for illustrated or video instructions for your specific model.
Q: What is the lens warranty period?
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.
Routine Lens Maintenance Tips
- Power off before changing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface while powered.
- Don't touch the lens elements: 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 before tightening: After installation, perform a focus test first, then tighten the fixing screws to prevent image drift from loosening over time.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while changing the lens is a safer practice.
