Zorsika WK242 projector lens, matched to original optical specifications, compatible with CX-LU65, CX-L69DU, CX-LU75, CX-LU85 and other 4 Digital China projectors.
When replacing the lens on an engineering projector, the biggest fear is buying one that won't fit. This article explains in one go which Shenzhou Yunke models the WK242 supports and what to watch out for when selecting it.

Where It Works: List of 4 Compatible Models (with Specifications)
The following are verified compatible models for the WK242 (Shenzhou Yunke projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| CX-LU65 | 6000 lumens | WUXGA 1920×1200 | — |
| CX-L69DU | 6000 lumens | WUXGA 1920×1200 | — |
| CX-LU75 | 7000 lumens | WUXGA 1920×1200 | — |
| CX-LU85 | 7000 lumens | WUXGA 1920×1200 | — |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is based on the body interface and optical structure. For models not on this list, please contact Zorsika technical support for confirmation.

Frequently Asked Questions
Q: What if the lens doesn't match the screen size?
A: First confirm the 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 size to Zorsika technical support, and we'll help you choose.
Q: My projector isn't on the list of 4 models above. Can I use the WK242?
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. To be safe, take photos of the body nameplate and the original lens and send them to Zorsika technical support for confirmation.
Q: Can this lens replace the original one?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no blurring at the edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in brightness loss and color shift that are immediately visible. For engineering and exhibition scenarios, Zorsika is recommended.
Q: Why choose Zorsika instead of the original manufacturer?
A: Zorsika lenses are produced according to the original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared to the original manufacturer, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty. Under normal use, non-human-caused damage (such as impact, water damage, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the date on the shipping document.
Same Specifications — Why Choose Zorsika
The WK242 is a commonly used lens for projects. Zorsika benchmarks it item by item against the original parameters, performs resolution testing on each unit before shipment, and backs its optical quality with data.
Zorsika's equivalent replacement model is compatible with 4 models including Shenzhou Yunke CX-LU65, CX-L69DU, CX-LU75, and CX-LU85. Enter WK242 in the Zorsika official website query system to see 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 level as the original, reducing light loss
- Stable Supply: Supports bulk purchasing 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 produced according to original drawings and offer better overall value.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk purchasing, we recommend getting 1 unit for testing first.
What to Watch Out For When Replacing the Lens
- Power off before replacing 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 operating with power on.
- Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass. If there's dust, use an air blower gently — don't wipe dry with a cloth.
- Focus before tightening: After installing in place, do a focus test first, then tighten the fixing screws, to avoid image drift from loosening over long-term use.
- Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer approach.
