Frequently Asked Questions
Q: What should I do 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 you're unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.
Q: My projector isn't on the list of 1 model above — can I use the SC228?
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 send a photo of the body nameplate and the original lens 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 specifications table above for the model) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with the same lens coating process, delivering sharp imaging with no blurry edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended.
Q: Why choose Zorsika instead of the original manufacturer?
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 a resolution test before leaving the factory. Compared with the original manufacturer, lead 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?
A: All Zorsika projector lenses come with a 12-month warranty. Under normal use and non-human-caused damage (such as impacts, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
Why Choose Zorsika
The SC228 is a commonly used lens for projects. Zorsika benchmarks it item by item against the original parameters, and each unit undergoes a resolution test before leaving the factory, so the optical quality is backed by data.
Zorsika's same-spec replacement model is compatible with the Full-Color Light Display WU20 and 1 other model; enter SC228 in the query system on the Zorsika official website to see the complete list of compatible models.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
- Resolution Testing: Each unit tested before shipment, with MTF data available
- Coating Process: Lens coating at the same level as the original, reducing light loss
- Stable Supply: Supports bulk purchasing and project supply
In one sentence: The lens is the optical core — 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 projector's condition and the installation environment. Before bulk purchasing, it's recommended to get 1 unit for testing first.
What to Watch Out for When Replacing a 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 smudges directly affect image quality. Hold the lens by the barrel without touching the glass; if there's dust, use an air blower to gently blow it off — don't wipe with a cloth.
- Focus before tightening: After installing it in place, do a focus test first, then tighten the fixing screws, to avoid the image drifting due to loosening over long-term use.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer approach.
