Frequently Asked Questions
Q: What if the lens doesn't match the screen 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 you're unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.
Q: My machine isn't on the list of 5 models above. Can I use the SC290?
A: The list covers verified models, but it doesn't represent all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take photos of the body nameplate and the original lens and send them 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 and directly determines clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no blurring at the edges. Ordinary replacement lenses often use ordinary glass lenses with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended as the first choice.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are produced according to the original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared with the original, delivery times are shorter and the overall value is better; compared with other replacement lenses, the optical quality is backed by data.
Q: How long is the lens warranty period?
A: All Zorsika projector lenses come with a 12-month warranty; under normal use and non-human damage (such as impact, water ingress, or unauthorized disassembly), you can contact after-sales service directly for handling. The warranty period is based on the date on the shipment document.
What Zorsika Lenses Offer You
Zorsika provides original-spec replacement lenses for the SC290, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika same-spec replacement model, compatible with 5 models including Appotronics AL-FU905, AL-FU805, AL-FU705, AL-FU10K, and AL-FU715; enter SC290 in the Zorsika official website query system to find the complete compatible model list.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
- Resolution Testing: Each unit tested before leaving the factory, with MTF data available
- Coating Process: Lens coating at the same level as the original, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In one sentence: the lens is the optical core, so don't gamble on image quality to save a few bucks — Zorsika projector lenses are produced according to original drawings and offer a better overall value.
Note: Actual imaging performance is affected by the body condition and installation environment. Before bulk procurement, it's recommended to get 1 unit for actual testing first.
What to Watch Out for When Replacing the 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 without touching the lens elements; if there's dust, use an air blower to gently blow it off, and don't wipe dry with a cloth.
- Focus before tightening: After installing in place, do a focus test first, then tighten the fixing screws, to avoid loosening over long-term use that causes image drift.
- Keep the interface clean: Dust accumulation on the mount and contacts can cause poor contact. Cleaning it while replacing the lens is safer.
