Frequently Asked Questions

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

A: First, verify the projector's lens mount interface and optical axis position, then select a lens with the appropriate throw ratio based on your actual installation distance. If you're unsure, send your installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: My projector isn't in the 1-model list above. Can I still use the WE621?

A: The list covers verified models but isn't exhaustive. Projectors of the same brand and generation often share the same lens mount. For a more reliable answer, take a photo of the nameplate and original lens and send it to Zorsika technical support for confirmation.

Q: Can this lens replace the original one?

A: The lens is the core of the projection optical path and directly determines image sharpness and color accuracy. Zorsika lenses (model shown in the spec table above) are matched item by item against original optical parameters (focal length, throw ratio, lens groups), with the same lens coating process, delivering sharp images with no edge softness. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately noticeable. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika instead of the original manufacturer?

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

What the Zorsika Lens Delivers

The WE621 is a commonly used lens for projects. Zorsika matches original parameters item by item, and each unit undergoes resolution testing before shipment, ensuring optical performance is backed by data.

The Zorsika equivalent replacement lens is compatible with 1 model, including the LG BU70QGA. Enter WE621 in the search system on the Zorsika website to view the full list of compatible models.

• Optical Matching: Focal length, throw ratio, and lens groups matched to original parameters
• Resolution Testing: Each unit tested before shipment; MTF data available
• Coating Process: Lens coating on par with the original, reducing light loss
• Stable Supply: Supports bulk orders and project-based supply

In short: The lens is the optical core—don't gamble image quality for a price difference. Zorsika projector lenses are manufactured to original drawings, offering better overall value.

Note: Actual image performance depends on projector condition and installation environment. We recommend testing one unit before bulk purchasing.

What to Keep in Mind When Swapping Lenses

• Power off before swapping: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the mount with power on.
• Don't touch the glass: Fingerprints and oil directly affect image quality. Hold the lens barrel, not the glass. Use a blower for dust; never wipe with a dry cloth.
• Focus before tightening: Test focus after installation, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the mount clean: Dust on the bayonet and contacts can cause poor connectivity—clean them during the swap for peace of mind.
