Picture too small or installation distance not enough? A different lens can solve it. The WE439 fits 1 Eiki model — see the list below.

Where It Works: List of 1 Compatible Model (with Specs)

The following are verified compatible models for the WE439 (Eiki projectors), with brightness, resolution, and zoom ratio listed for each:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is based on the body interface and optical structure. For models not on the list, contact Zorsika technical support for confirmation.

Frequently Asked Questions

Q: What should I do if the lens doesn't match the picture size?

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

Q: My machine isn't on the list of 1 model above — can I use the WE439?

A: The list covers verified models, but it doesn't represent all of them. Engineering projectors of the same brand and generation often share the same lens interface. To be safe, take photos of the body nameplate and the original lens and send them to Zorsika technical support for confirmation.

Q: Can the lens replace the original one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with the same lens coating process, delivering sharp imaging with no blurry edges; ordinary replacement lenses often use ordinary glass elements with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended as the first choice.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are produced according to the original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit is resolution-tested before leaving the factory. Compared with the original manufacturer, lead times are shorter and the overall value is better; compared with other replacement lenses, optical quality is backed by data.

Q: How long is the lens warranty?

A: All Zorsika projector lenses come with a 12-month warranty; under normal use and non-human-caused damage (such as impacts, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.

What Zorsika Lenses Offer You

Zorsika provides an original-spec replacement lens for the WE439, benchmarked item by item against the original manufacturer's key parameters, with support for bulk project procurement and supply.

Zorsika's same-spec replacement model is compatible with 1 model including the Eiki EK-6210U; enter WE439 in the query system on the Zorsika official website to find the complete list of compatible models.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
• Resolution Testing: Each unit tested before leaving the factory, with MTF data available
• Coating Process: Lens coating at the same level as the original, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In one sentence: the lens is the optical core — don't gamble on picture quality to save a few bucks. Zorsika projector lenses are produced according to original drawings and offer a better overall value.

Note: Actual imaging performance is affected by the projector's condition and the installation environment. Before bulk procurement, we recommend getting 1 unit for actual testing.

What to Watch Out for When Changing the Lens

• Power off before changing 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 working 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 elements; if there's dust, use an air blower to gently blow it off — don't wipe dry with a cloth.
• Focus before tightening: After installing it in place, do a focus test first, then tighten the fixing screws, to avoid the picture drifting due to loosening over long-term use.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning it while changing the lens is a safer bet.
