Frequently Asked Questions

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

A: First confirm the lens interface and optical axis position of your projector, then select a lens with the appropriate throw ratio based on your actual installation distance; if you're unsure, send us the installation distance and screen dimensions and Zorsika technical support will help you find the right recommendation.

Q: My model isn't on the list above, can I use WJ251?

A: The list shows verified models only, not all compatible models. Projectors from the same brand and generation often share lens interfaces. Send photos of the unit nameplate and original lens to Zorsika technical support for confirmation to be safe.

Q: Can this lens replace the OEM lens?

A: The lens is the core of the projector's optical path, directly determining sharpness and color accuracy. Zorsika lenses (models in the specifications table above) are matched item by item against original optical parameters (focal length, throw ratio, lens elements), with consistent coating processes, delivering sharp imaging without edge softening; ordinary replacement lenses often use regular glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over the OEM?

A: Zorsika lenses are manufactured according to original optical drawings, with lens elements, coatings and throw ratios matched item by item, and each unit undergoes resolution testing before shipment. Compared to OEM, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical quality is backed by test data.

Q: What's the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty; normal use and non-human damage (such as impacts, water damage, unauthorized disassembly) can be directly handled through after-sales service, with the warranty period based on the shipping document date.

Why Choose Zorsika

WJ251 is a commonly used lens in projects. Zorsika benchmarks each specification against the original manufacturer's parameters, and every unit undergoes resolution testing before shipment, ensuring optical performance with documented data.

Zorsika offers same-specification replacement models, compatible with 1 model including Unimicro F80A. Enter WJ251 in the query system on Zorsika's official website to find the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens elements matched to original manufacturer specifications
• Resolution Testing: Every unit tested before shipment, MTF data available
• Coating Technology: Lens coatings at the same grade as OEM, minimizing light loss
• Stable Supply: Supports bulk purchasing and project-based procurement

Bottom line: The lens is the optical core—don't compromise image quality for price differences. Zorsika projector lenses are manufactured according to original factory blueprints, offering overall advantages.

Note: Actual imaging performance depends on the projector's condition and installation environment. It is recommended to test one unit before bulk purchase.

What to Watch Out for When Replacing the Lens?

• Power off first: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid interface damage from live operations.
• Do not touch the lens elements: Fingerprints and oil stains directly degrade image quality. Grip the lens barrel without touching the glass; use an air blower to gently remove dust, do not wipe with cloth.
• Lock after focusing: After installing, test the focus first, then tighten the mounting screws to prevent loosening during long-term use that causes image drift.
• Keep interfaces clean: Dust buildup on bayonets and contacts causes poor connection; clean them while replacing the lens for better reliability.
