Why Choose Zorsika
Zorsika offers an OEM-spec replacement lens for the SC291, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika OEM-spec replacement model, compatible with 6 Appotronics models including AL-SH10K, AL-SU10K, AL-SU12K, AL-SU13K, AL-SU15K; enter SC291 in the Zorsika official website query system to view 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, 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 bucks. 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.
What to Watch Out for When Replacing the Lens
- Power off before replacing 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 on.
- Don't touch the glass: 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—do not dry-wipe with a cloth.
- Focus first, then tighten: After installing properly, focus and test first, then tighten the fixing screws to prevent the image from drifting due to loosening over time.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer bet.
FAQ
Q: My projector isn't on the list of 6 models above—can I use the SC291?
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 send photos of the model nameplate and original lens to Zorsika technical support for confirmation.
Q: Can this 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 group), with matching lens coating processes—delivering sharp imaging with no soft edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with 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 select 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 SC291 come with installation instructions?
A: Yes. The lens removal and installation steps for Appotronics models are basically the same. Contact Zorsika sales for illustrated or video instructions for your specific 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 damage (such as impact, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipment document.
