Zorsika WA105 Projector Lens Compatible Models: Dihang DU21K DU22K DU26K OEM Compatible

Picture too small or installation distance not enough? A different lens can solve it. WA105 fits 3 Diheng projector models — see the list below.

Compatible projector models: 3 Diheng projectors (with brightness, resolution, and zoom ratio)

The following are the verified compatible models for the WA105 (Diheng 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 listed, contact Zorsika technical support for confirmation.

Frequently Asked Questions

Q: What 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 your actual installation distance. If 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 list of 3 models above — can I use the WA105?

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. It's safer to send a photo of the nameplate and the original lens 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 (model see the specification table above) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no blurry edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, and brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended.

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 undergoes resolution testing before leaving the factory. Compared with the original manufacturer, lead times are shorter and 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 impact, 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

For engineering lenses like the WA105, Zorsika benchmarks item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no blurry edges — ready to use once installed.

Zorsika's equivalent replacement model fits 3 projector models including the Diheng DU21K, DU22K, and DU26K; enter WA105 in the query system on the Zorsika official website to see the complete model compatibility list.

• 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 purchasing and project supply

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

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

What to Watch Out for When Changing Lenses

• 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 will directly affect image quality. Hold the lens by the barrel, not the glass; if there's dust, use an air blower gently — don't wipe dry with a cloth.
• Focus before tightening: After installing 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 them while changing the lens is a safer practice.
