What Zorsika Lenses Offer You
The WB310 is a commonly used lens for projects. Zorsika benchmarks each item against the original factory parameters, and every unit undergoes resolution testing before leaving the factory, ensuring optical quality backed by data.
Zorsika's same-spec replacement model is compatible with 12 models including ViewSonic EL600, EL650, EL700, SML-ES600H, SML-ES550H, etc.; enter WB310 in the Zorsika official website query system to find the complete compatible model list.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original factory parameters
- Resolution Testing: Each unit tested before shipment, with MTF data available
- Coating Process: Lens coatings at the same level as the original factory, 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 according to original factory drawings, offering comprehensive advantages.
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 a 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. For dust, use an air blower gently; do not wipe dry with a cloth.
- Focus first, then tighten: After installing in place, focus and test first, then tighten the fixing screws to avoid image drift from loosening during long-term use.
- Keep the interface clean: Dust accumulation on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer practice.
Frequently Asked Questions
Q: My projector is not on the list of 12 models above. Can I use the WB310?
A: The list contains verified models, not all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take a photo of the nameplate and the original lens and send it 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 and directly determines clarity and color. Zorsika lenses (model numbers as in the specification table above) are benchmarked item by item against original factory optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no blurry edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.
Q: Why choose Zorsika instead of the original factory?
A: Zorsika lenses are manufactured according to original factory optical drawings, with lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before shipment. Compared to the original factory, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.
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: Does the WB310 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 obtain 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. 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 shipping document.
