WD301 Model Compatibility List (3 Models Total, with Brightness/Resolution/Zoom Ratio)
The following are verified compatible models for the WD301 (ViewSonic projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| LS860WU+ | — | — | — |
| LS921WU | 6000 lumens | WUXGA 1920×1200 | 1.1X |
| LS920WU | 6000 lumens | WUXGA 1920×1200 | 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 body interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.
What the Zorsika Lens Offers You
Zorsika provides an OEM-spec replacement lens for the WD301, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika's OEM-spec replacement model is compatible with 3 ViewSonic models including LS860WU+, LS921WU, and LS920WU; enter WD301 in the query system on the Zorsika official website to find the complete model compatibility list.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
- Resolution Testing: Each unit tested before leaving the factory, with traceable MTF data
- Coating Process: Lens coating 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 produced according to original drawings and offer a comprehensive advantage.
Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 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 working with power on.
- Don't touch the glass: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust — do not wipe dry with a cloth.
- Focus before tightening: After installing in place, test the focus 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 bet.
You Might Want to Ask
Q: My machine isn't on the list of 3 models above — can I use the WD301?
A: The list covers verified models, not all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to send photos of the nameplate and original lens 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 (model shown in the specification table above) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens group), with the same lens coating process, delivering sharp imaging with no soft edges; ordinary replacement lenses often use ordinary glass elements with insufficient coating layers, making brightness loss and color shift obvious at a glance. For engineering and exhibition scenarios, Zorsika is recommended.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are produced according to 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 with the original, lead times are shorter and the 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 the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support and we'll help you choose.
Q: Does the WD301 come with installation instructions?
A: Yes. The lens removal and installation steps for ViewSonic models like these are basically the same. Contact Zorsika sales to get illustrated or video instructions for the corresponding model.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty; under normal use, non-human 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 shipment document.
