Why Choose Zorsika

WE281 is a commonly used projector lens in projects. Zorsika performs parameter-by-parameter alignment with OEM specifications, and each lens undergoes resolution testing before shipment, ensuring documented optical quality.

Zorsika offers alternative models with the same specifications, compatible with Yunguo F67B and 1 other model. Enter WE281 in the query system on the Zorsika official website to find the complete compatible model list.

• Optical Benchmarking: Focal length, throw ratio and lens elements are matched to OEM specifications
• Resolution Testing: Each lens is tested before shipment, with MTF data available for review
• Coating Process: Lens coating matches OEM grade, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based orders

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

Note: Actual imaging performance may vary depending on chassis condition and installation environment. It is recommended to test one unit before bulk procurement.

What to Watch for When Replacing the Lens?

• Power off before lens replacement: Be sure to shut down and wait for the cooling fan to stop before disassembling or installing the lens to avoid interface damage from live operation.
• Do not touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel without touching the glass. Use an air blower to gently remove dust; do not wipe with cloth.
• Lock after focusing: After proper installation, test focusing first, then tighten the securing screws. Loose screws over long-term use may cause image drift.
• Keep the interface clean: Dust on the mount and contacts may cause poor connection. Clean during lens replacement for better reliability.

Frequently Asked Questions

Q: My machine is not on the list above. Can I use WE281?

A: The list shows verified models only, not all compatible models. Machines of the same brand and generation often share lens interfaces. It's safer to take a photo of the machine's nameplate and the original lens and send them to Zorsika technical support for confirmation.

Q: Can the lens replace the OEM lens?

A: The lens is the core of the projection optical path, directly determining clarity and color accuracy. Zorsika lenses (model numbers in the specification table above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens assembly), with consistent lens coating工艺. The imaging is sharp and edges are not blurred. Ordinary replacement lenses often use regular glass elements with insufficient coating layers, resulting in noticeable brightness loss and color deviation. For engineering and exhibition applications, Zorsika is recommended as the priority choice.

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to OEM optical drawings, with lens assembly, coating, and throw ratio matched item by item. Each lens undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter delivery times and better overall value. Compared to other replacement lenses, optical quality is guaranteed with data.

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

A: First confirm the machine's lens interface and optical axis position, then select a lens with the corresponding throw ratio based on your actual installation distance. If you're unsure, send your installation distance and screen dimensions to Zorsika technical support and we'll help you with recommendations.

Q: Does WE281 come with installation instructions?

A: Yes. The lens removal and installation steps are basically the same for machines like YunGuo. Contact Zorsika sales to get illustrated or video instructions for your specific model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human-caused damage (such as impacts, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is calculated from the invoice date.
