What Zorsika Lenses Offer You
Zorsika provides OEM-spec replacement lenses for the SC33+, with key parameters benchmarked item by item against the original. Bulk project procurement and supply are supported.
Zorsika OEM-spec replacement model, compatible with Optoma ZK750, ZK1050, and other 2 models; enter SC33+ 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 OEM parameters
- Resolution Testing: Each unit tested before shipment, with traceable MTF data
- Coating Process: Lens coatings at OEM level to reduce light loss
- Stable Supply: Bulk procurement and project supply supported
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 OEM 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 hands-on testing.
You Might Want to Ask
Q: Why choose Zorsika instead of OEM?
A: Zorsika lenses are manufactured to OEM optical drawings, with the lens group, coatings, and throw ratio benchmarked item by item, and each unit resolution-tested before shipment. Compared to OEM, 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 OEM one?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (models listed in the specification table above) are benchmarked item by item against OEM optical parameters (focal length, throw ratio, lens group), 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 obvious at a glance. For engineering and exhibition scenarios, Zorsika is recommended as the first choice.
Q: My projector isn't on the list of 2 models above — can I use the SC33+?
A: The list covers verified models but does not represent all. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to send photos of the body nameplate and the original lens to Zorsika technical support for confirmation.
Q: Does the SC33+ come with installation instructions?
A: Yes. The lens removal and installation steps for Optoma models like these 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; under normal use, non-human-caused damage (such as impact, water damage, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the date on the shipment document.
Daily 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 with live power.
- Don't touch the lens elements: Fingerprints and oil smudges directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust — don't dry-wipe with a cloth.
- Focus first, then tighten: After installation, do a focus test first, then tighten the fixing screws, to avoid 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.
