Frequently Asked Questions

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

A: First verify the projector's lens interface and optical axis position, then select a lens with the corresponding throw ratio based on your actual installation distance. If unsure, send the installation distance and screen dimensions to Zorsika Technical Support—we'll help you choose.

Q: My projector isn't on the list of 12 models. Can I still use BE141（<15K Lumens）?

A: The list represents verified models only—not an exhaustive catalog. Projectors from the same brand and generation often share common lens interfaces. For confirmation, send photos of the unit's nameplate and original lens to Zorsika Technical Support.

Q: Can this lens replace the OEM lens?

A: The lens is the core of the projection light path, directly determining clarity and color accuracy. Zorsika lenses (models listed in the specifications above) are matched item-by-item against OEM optical parameters (focal length, throw ratio, lens elements), with identical lens coating processes—delivering sharp imaging without edge blurring. Generic replacement lenses often use ordinary glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over the OEM?

A: Zorsika lenses are manufactured to OEM optical blueprints, with lens assemblies, coatings, and throw ratios matched precisely. Each unit undergoes resolution testing before shipment. Compared to OEM options, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika guarantees optical quality backed by test data.

Q: What is the lens warranty period?

A: All Zorsika projector lenses are backed by a 12-month warranty. Normal use and non-human damage (such as impacts, water damage, or unauthorized disassembly) can be addressed directly through after-sales service. Warranty period is calculated from the shipping invoice date.

What Zorsika Lenses Offer You

Zorsika provides OEM-spec replacement lenses for BE141 (<15K Lumens), with key parameters matched item by item to the originals, supporting bulk project procurement and supply.

Zorsika OEM-spec replacement models are compatible with Christie, Optoma DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, ZK1320 and 12 other models; enter BE141 (<15K Lumens) in the Zorsika official website query system to find the complete compatible model list.

  • Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
  • Resolution Testing: Each lens tested before shipping, MTF data available for review
  • Coating Process: Lens coating at the same grade as OEM, reducing light loss
  • Stable Supply: Supports bulk procurement and project-based supply

Bottom line: The lens is the optical core—don't gamble with image quality over price differences. Zorsika projector lenses are manufactured according to OEM specifications, offering overall better value.

Note: Actual imaging performance depends on chassis condition and installation environment. It is recommended to test one unit before bulk procurement.

What to Watch for When Replacing the Lens?

  • Disconnect Power Before Lens Replacement: Always power off and wait for the cooling fan to stop before removing or installing the lens to prevent interface damage from live operations.
  • Avoid Touching the Lens: Fingerprints and oils directly degrade image quality. Hold the lens barrel without touching the lens surface. Use an air blower for dust; do not wipe with cloth.
  • Lock After Focusing: After proper installation, test focusing first, then tighten the mounting screws. This prevents loosening over time that causes image drift.
  • Keep Interface Clean: Dust buildup on mounts and contacts causes poor connectivity. Clean during lens replacement for better reliability.
