Frequently Asked Questions

Q: What if the lens doesn't match the screen size?

A: First, confirm the projector's lens interface and optical axis position. Then, select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send the installation distance and screen dimensions to Zorsika technical support for a recommendation.

Q: My projector isn't on the list of 6 models. Can I still use the SC340?

A: The list contains verified models, but it's not exhaustive. Projectors from the same brand and generation often share lens interfaces. For a more reliable confirmation, send photos of the projector's nameplate and the original lens to Zorsika technical support.

Q: Can this lens replace the original manufacturer's lens?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model see specifications table above) are matched item-by-item to the original optical parameters (focal length, throw ratio, lens group) with consistent lens coating processes, resulting in sharp imaging without soft edges. Generic replacement lenses often use standard glass elements with insufficient coating layers, leading to noticeable brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are produced according to the original optical blueprints, with item-by-item matching of lens groups, coatings, and throw ratios. Each lens undergoes resolution testing before shipment. Compared to the original, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical quality is data-backed.

Q: What is the warranty period for the lens?

A: Zorsika offers a 12-month warranty on all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.

Why Zorsika for the Same Specifications

For engineering lenses like the SC340, Zorsika matches the original optical parameters (focal length, throw ratio, lens group) item-by-item. The consistent lens coating process ensures sharp imaging without soft edges, ready for immediate installation.

Zorsika's equivalent replacement model is compatible with 6 Christie models including DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, 4K1400-KS, etc. Enter SC340 in the query system on the Zorsika official website to find the complete list of compatible models.

  • Optical Matching: Focal length, throw ratio, and lens group matched to original parameters
  • Resolution Testing: Each lens is tested before shipment; MTF data available
  • Coating Process: Lens coating is equivalent to the original, minimizing light loss
  • Stable Supply: Supports bulk purchasing and project supply

In summary: The lens is the optical core—don't gamble image quality for a price difference. Zorsika projector lenses are produced according to original blueprints, offering superior overall performance.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For bulk purchases, it is recommended to first obtain one unit for testing.

What to Note When Changing Lenses

  • Power off before changing: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface.
  • Avoid touching the lens: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass. Use a blower for dust; do not wipe dry with a cloth.
  • Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws to prevent image drift from loosening over time.
  • Clean the interface: Dust on the mount and contacts can cause poor connection. Clean them when changing lenses for reliability.
