Picture too small or installation distance not enough? A different lens can solve it. The WK166 fits 7 Diheng projector models — see the list below.
Zorsika WK166 Projector LensWhere It Works: List of 7 Compatible Models (with Specs)
The following are verified compatible models for the WK166 (Diheng projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| DK5600 | 5650 lumens | 4K (3840×2160) | 1.6X |
| DK6200 | 6200 lumens | 4K (3840×2160) | 1.6X |
| QD6050 | 6050 lumens | WUXGA 1920×1200 | 1.6X |
| QD605ST | 6050 lumens | WUXGA 1920×1200 | 1.1X |
| SH-DU655ST | 6050 lumens | WUXGA 1920×1200 | 1.1X |
| SH-YW6550 | 6550 lumens | WUXGA 1920×1200 | 1.6X |
| SH-DU6550 | 6550 lumens | WUXGA 1920×1200 | 1.6X |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility depends on the body interface and optical structure. For models not on this list, contact Zorsika technical support for confirmation.

Frequently Asked Questions
Q: What if the lens doesn't match the screen 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 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 on the list of 7 models above — can I use the WK166?
A: The list covers verified models, not all of them. Engineering projectors of the same brand and generation often share the same lens interface. To be safe, take a photo of the body nameplate and the original lens and send it 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 — sharp imaging with no blurring at the edges. Ordinary replacement lenses often use plain glass elements with insufficient coating layers, and the loss of brightness 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 is resolution-tested before leaving the factory. Compared with the original, 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, non-human-caused damage (such as impact, water damage, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the date on the shipment document.
What Zorsika Lenses Offer You
Zorsika provides original-spec replacement lenses for the WK166, benchmarked item by item against the original on key parameters, with support for bulk project procurement and supply.
Zorsika original-spec replacement model, compatible with 7 models including Diheng DK5600, DK6200, QD6050, QD605ST, and SH-DU655ST; enter WK166 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 procurement and project supply
In short: the lens is the optical core — don't gamble on image 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 depends on the projector's condition and the installation environment. Before bulk procurement, we recommend getting 1 unit for a hands-on test.
What to Watch Out for When Changing a Lens
- Power off before changing the lens: Be sure to shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface while powered.
- Don't touch the lens elements: Fingerprints and oil smudges 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 first, then tighten: After installing it in place, do a focus test first, then tighten the fixing screws, to avoid the picture drifting from 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 the safer approach.
