FAQ

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

A: First confirm the lens mount and optical axis position of your projector model, then select a lens with the appropriate throw ratio based on the actual installation distance. If you're unsure, send the installation distance and screen dimensions to Zorsika technical support and we'll help you choose.

Q: My projector isn't on the list of 12 models. Can I use the BE591 (<12K Lumens)?

A: The list contains verified models but is not exhaustive. Projectors of the same brand and generation often share lens mounts. For better accuracy, send photos of the projector nameplate and original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the OEM lens?

A: The lens is the core of the projector's optical path and directly determines clarity and color accuracy. Zorsika lenses (models listed in the specifications table above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens elements) with consistent lens coating processes, delivering sharp imaging without edge blur. Ordinary replacement lenses often use regular glass elements 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 OEM?

A: Zorsika lenses are manufactured according to OEM optical specifications, with lens elements, coatings, and throw ratios matched item by item, and each unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika guarantees optical quality with test data.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human damage (such as impact, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the shipping document date.

What Zorsika Lens Can Offer You

Zorsika offers OEM-spec equivalent replacement lenses for BE591 (<12K Lumens), with key parameters matching the original manufacturer item by item, supporting bulk project procurement and supply.

Zorsika OEM-spec equivalent models are compatible with Christie, Optoma DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, ZK1320 and 12 other models; enter BE591 (<12K Lumens) in the Zorsika official website query system to find the complete model compatibility list.

  • Optical alignment: Focal length, throw ratio, and lens elements are matched according to original manufacturer specifications
  • Resolution testing: Each lens is tested before shipment, with MTF data available upon request
  • Coating process: Lens coatings are equivalent to the original manufacturer grade, minimizing light loss
  • Stable supply: Supports bulk procurement and project-based orders

To summarize: A lens is the core of optical performance—don't risk image quality for a price difference. Zorsika projector lenses are manufactured according to original manufacturer drawings, offering comprehensive advantages.

Note: Actual imaging performance may vary depending on the projector condition and installation environment. It is recommended to obtain one lens for testing before bulk procurement.

What to Watch Out for When Replacing the Lens?

  • Power off before replacing the lens: Be sure to turn off the projector and wait for the cooling fan to stop before removing or installing the lens. Avoid working on a powered-on unit to prevent interface damage.
  • Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel without touching the elements; use an air blower to gently remove dust—do not wipe with cloth.
  • Lock tight after focusing: After proper installation, test the focus first, then tighten the mounting screws. This prevents image drift caused by loosening during long-term use.
  • Keep interfaces clean: Dust buildup on bayonets and contacts can cause poor connection. Cleaning during lens replacement is more reliable.
