Where It Works: List of 3 Compatible Models (with Specifications)
Below are the verified compatible models for the WE305 (ViewSonic projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| LS960WU | 8500 lumens | WUXGA 1920×1200 | 1.6X |
| LS950WU | 8200 lumens | WUXGA 1920×1200 | 1.6X |
| LS950-4K | 8200 lumens | 4K (3840×2160) | 1.6X |
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 chassis interface and optical structure. For models not on the list, contact Zorsika technical support for confirmation.
Same Specifications—Why Choose Zorsika
Zorsika offers an OEM-equivalent replacement lens for the WE305, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika's OEM-equivalent replacement model is compatible with the ViewSonic LS960WU, LS950WU, LS950-4K, and other 3 models; enter WE305 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 traceable MTF data
- Coating Process: Lens coatings at the same level as the original, reducing light loss
- Stable Supply: Supports bulk procurement 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 manufactured to original drawings and offer a stronger overall value.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend getting 1 unit for hands-on testing.
What to Watch Out for When Swapping Lenses
- Power off before swapping: Always shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface while powered.
- Don't touch the glass: Fingerprints and oil directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower for dust—don't dry-wipe with a cloth.
- Focus, then tighten: After installation, focus-test first, then tighten the fixing screws, to avoid image drift from loosening over time.
- Keep the interface clean: Dust on the mount and contacts causes poor contact—cleaning it while swapping lenses is the safer move.
FAQ
Q: My machine isn't on the list of 3 above—can I use the WE305?
A: The list covers verified models, not all of them. Same-brand, same-generation engineering projectors often share lens interfaces. It's safer to send photos of the model nameplate and original lens to Zorsika technical support for confirmation.
Q: Can the lens replace the original?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model shown in the spec table above) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens group), with matching lens coating processes for sharp imaging and no soft edges; ordinary replacement lenses often use plain glass elements with insufficient coating layers, making brightness loss and color shift obvious at a glance. For engineering and exhibition scenarios, Zorsika is the recommended choice.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with the lens group, coatings, and throw ratio benchmarked item by item, and each unit resolution-tested before shipment. Compared with the original, lead times are shorter and overall value is better; compared with other replacement lenses, optical quality is backed by data.
Q: What if the lens doesn't match the image size?
A: First confirm the model's lens interface and optical axis position, then choose a lens with the corresponding throw ratio based on your actual installation distance. If unsure, send your installation distance and screen size to Zorsika technical support and we'll help you choose.
Q: Does the WE305 come with installation instructions?
A: Yes. Lens removal and installation steps are basically the same across ViewSonic models like these. Contact Zorsika sales for illustrated or video instructions for your specific model.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-human-caused damage (such as impact, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
