SC231 Compatible Projector Models (1 model total, with brightness/resolution/zoom ratio)
The following are verified compatible projector models for the SC231 (NEC projectors), each with brightness, resolution, and zoom ratio:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| NP-PX2201UL+ | 20500 lumens | WUXGA 1920×1200 | NP45ZL( 0.9~1.2) NP46ZL(1.2~1.56) NP47ZL(1.5~2.0) NP48ZL(2.0~4.0) NP49ZL(4.0~7.0） |
Note: Brightness, resolution, and zoom ratio are sourced from the Zorsika product database (refer to the projector nameplate/manual for accuracy); lens compatibility is based on chassis interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.
What Zorsika Lenses Offer
For engineering lenses like the SC231, Zorsika aligns each specification with the original manufacturer's optical parameters (focal length, throw ratio, lens group). The lens coating process is consistent, producing sharp images without edge softening, ready for immediate installation.
Zorsika offers equivalent replacement models, compatible with the NEC NP-PX2201UL+ and 1 other model; enter SC231 in the Zorsika official website search system to find the complete compatible model list.
- Optical Alignment: Focal length, throw ratio, and lens group matched to original manufacturer specifications
- Resolution Testing: Each lens tested before shipment, MTF data available upon request
- Coating Process: Lens coating matches factory-grade standards, minimizing light loss
- Stable Supply: Supports bulk procurement and project-based delivery
In summary: The lens is the optical core—don't compromise on image quality for price differences. Zorsika projector lenses are manufactured according to original manufacturer specifications, offering comprehensive advantages.
Note: Actual imaging performance may vary depending on chassis condition and installation environment. It is recommended to test one unit before bulk procurement.
What to Watch Out for When Replacing the Lens?
- Power off before replacing the lens: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with live operations.
- Don't touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently blow away dust, do not wipe with dry cloth.
- Lock after focusing: After properly installing, test the focus first, then tighten the fixing screws to prevent loosening over time that could cause image drift.
- Keep the interface clean: Dust on the mount and contacts can cause poor connection; clean them while replacing the lens for better reliability.
Frequently Asked Questions
Q: My projector isn't on the list above. Can I use SC231?
A: The list shows verified models only, not all compatible ones. Projectors of the same brand and generation often share lens interfaces. Send photos of the machine nameplate and original lens to Zorsika technical support for confirmation.
Q: Can the lens replace the original manufacturer's?
A: The lens is the core of the projector's optical path, directly determining sharpness and color accuracy. Zorsika lenses (models in the specification table above) are matched item by item against original optical parameters (focal length, throw ratio, lens elements), with consistent lens coating process, producing sharp images without soft edges. Common replacement lenses often use ordinary glass with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.
Q: Why choose Zorsika over the original manufacturer?
A: Zorsika lenses are manufactured according to original optical specifications, with lens elements, coating, and throw ratio matched item by item. Every unit undergoes resolution testing before shipment. Compared to original manufacturers, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical performance is backed by test data.
Q: The lens doesn't match the screen size. What should I do?
A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send your installation distance and screen dimensions to Zorsika technical support—we'll help you choose.
Q: Is there an installation guide for SC231?
A: Yes. Lens removal and installation steps are basically the same for NEC and similar models. Contact Zorsika sales to get illustrated or video instructions for your specific model.
Q: What's the warranty period for the lens?
A: All Zorsika projector lenses come with 12 months warranty. Normal use and non-human damage (such as impacts, water damage, or unauthorized disassembly) can be handled through after-sales service. Warranty period is based on the shipping document date.
