What Zorsika Lenses Offer You
Zorsika provides an original-specification replacement lens for the WK281 (<18K Lumens), with key parameters matching the original factory specifications, supporting bulk project procurement and supply.
Zorsika's equivalent replacement model is compatible with 6 Christie models including DWU1800-JS, DWU2400-JS, 4K1600-JS, 4K2100-JS, 4K1400-KS, etc.; enter WK281 (<18K Lumens) in the Zorsika official website query system to find the complete list of compatible models.
- Optical Matching: Focal length, throw ratio, and lens group match original factory parameters.
- Resolution Testing: Each unit is tested before shipment; MTF data is available.
- Coating Process: Lens coating is equivalent to the original factory level, reducing light loss.
- Stable Supply: Supports bulk procurement and project supply.
In one sentence: The lens is the optical core; don't gamble image quality for a price difference — Zorsika projector lenses are produced according to original factory drawings, offering a comprehensive advantage.
Note: Actual imaging performance is affected by the projector's condition and installation environment. For bulk procurement, it is recommended to first obtain one unit for testing.
What to Note 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 operation.
- Avoid touching the lens elements: 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.
- Lock after focusing: After installation, perform a focus test first, then tighten the fixing screws to prevent image drift from loosening during long-term use.
- Keep the interface clean: Dust on the bayonet and contacts can cause poor connection. Clean them conveniently when replacing the lens.
Frequently Asked Questions
Q: My projector is not on the list of 6 models above. Can I use the WK281 (<18K Lumens)?
A: The list contains verified models and does not represent all possibilities. Engineering projectors of the same brand and generation often share lens interfaces. It is more reliable to send a photo of the projector's nameplate and original lens to Zorsika technical support for confirmation.
Q: Can the lens replace the original factory one?
A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model see specifications table above) match original factory optical parameters (focal length, throw ratio, lens group) item by item, with consistent lens coating processes, resulting in sharp imaging without soft edges; ordinary 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 factory?
A: Zorsika lenses are produced according to original factory optical drawings, with item-by-item matching of lens group, coating, and throw ratio. Each unit undergoes resolution testing before shipment. Compared to the original factory, delivery times are shorter and overall value is better; compared to other replacement lenses, optical quality is data-guaranteed.
Q: What if the lens doesn't match the screen size?
A: First confirm the projector model's lens interface and optical axis position, then select a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen dimensions to Zorsika technical support, and we will recommend a suitable option.
Q: Does the WK281 (<18K Lumens) come with installation instructions?
A: Yes. The lens removal and installation steps for Christie models like these are generally consistent. Contact Zorsika sales to obtain the corresponding model's illustrated or video instructions.
Q: What is the warranty period for the lens?
A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human-caused damage (such as impact, water ingress, or unauthorized disassembly), you can directly contact after-sales service. The warranty period is based on the shipping document date.
