Frequently Asked Questions

Q: What if the lens doesn't match the screen size?

A: First confirm the lens mount and optical axis position of your projector model, then select a lens with the appropriate throw ratio based on the actual installation distance. If you're unsure, send the installation distance and screen size to Zorsika Technical Support—we'll help you find the right recommendation.

Q: My machine isn't in the list of 6 models above. Can I use LA01A?

A: The list represents verified models only, not an exhaustive catalog. Projectors of the same brand and generation often share the same lens mount. For better accuracy, take a photo of the machine nameplate and original lens and send it to Zorsika Technical Support for confirmation.

Q: Can this lens replace the OEM lens?

A: The lens is the core of the projection light path, directly determining sharpness and color accuracy. Zorsika lenses (models listed in the specification table above) are matched item by item against OEM optical parameters—focal length, throw ratio, and lens elements—with consistent coating工艺. The result is sharp imaging with no edge softening. Ordinary replacement lenses typically use standard glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens elements, coatings, and throw ratios matched item by item. Every unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, optical quality is backed by test data.

Q: What is the lens warranty period?

A: All Zorsika projector lenses are covered by a 12-month warranty. Normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly) can be directly addressed through after-sales service. The warranty period is calculated from the shipping invoice date.

What Zorsika Lenses Deliver

LA01A is a commonly used project lens. Zorsika matches every parameter against the OEM specifications and performs resolution testing on each unit before shipment, with optical quality guaranteed by test data.

Zorsika's equivalent replacement model is compatible with 6 models: Keyema EFL-WU72, EFL-WU66, EFL-WU86, EFL-4K76, and QLP-G950U. Enter LA01A in the query system on the Zorsika official website to find the complete model compatibility list.

• Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
• Resolution Testing: Every unit tested before shipment; MTF data available on request
• Coating Process: Lens coatings match OEM grade, minimizing light loss
• Stable Supply: Supports bulk orders and project fulfillment

Bottom line: The lens is the optical core—don't compromise on image quality for a price difference. Zorsika projector lenses are manufactured according to OEM blueprints, offering better overall value.

Note: Actual imaging performance depends on the machine condition and installation environment. For bulk orders, we recommend ordering one unit for testing first.

What to Watch for When Replacing a Lens

• Power off before lens replacement: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens. Avoid working with the power on to prevent interface damage.
• Don't touch the lens elements: Fingerprints and oils directly degrade image quality. Hold the lens by the barrel, not the glass. For dust, use an air blower to gently clean—never wipe with cloth.
• Lock after focusing: After installing the lens, test the focus first, then tighten the mounting screws. This prevents gradual loosening that could cause image drift over time.
• Keep interfaces clean: Dust on the bayonet mount and contacts can cause poor connection. Clean them while replacing the lens for best results.
