Same Specifications — Why Choose Zorsika
Zorsika offers an OEM-equivalent replacement lens for the SC34+, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika's equivalent replacement model is compatible with Christie and Optoma DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, 4K1400-KS and 8 other models, totaling 12; enter SC34+ 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, with 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 stronger overall value.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing.
You May Want to Ask
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with the lens group, coatings, and throw ratio benchmarked item by item, and each unit resolution-tested before shipment. Compared with the original, lead times are shorter and overall value is better; compared with other replacement lenses, optical quality is backed by data.
Q: Can the lens replace the original?
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 original 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.
Q: My machine isn't in the 12-model list above — can I use the SC34+?
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 photos of the body nameplate and the original lens to Zorsika technical support for confirmation.
Q: Does the SC34+ come with installation instructions?
A: Yes. The lens removal and installation steps for Christie and Optoma models like these are basically the same. Contact Zorsika sales to obtain 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 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.
Routine Lens Maintenance Tips
- Power off before changing 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 working with power on.
- Don't touch the lens elements: Fingerprints and oil smudges directly affect image quality. Hold the lens by the barrel, not the glass; use a blower to gently remove dust — don't wipe dry with a cloth.
- Focus first, then tighten: After installing properly, focus and test first, then tighten the fixing screws, to avoid loosening over time that causes image drift.
- 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.
