Compatible Projectors: 4 Shenzhou Yunke Models (Brightness, Resolution, Zoom Ratio)

The following are verified compatible projectors for the WD437 (Shenzhou Yunke projectors), with brightness, resolution and zoom ratio for each model:

Note: Brightness, resolution and zoom ratio are sourced from the Zorsika product database (subject to the model nameplate/manual for accuracy). Lens compatibility is based on the unit interface and optical structure. For models not listed, please contact Zorsika Technical Support for verification.

Why Choose Zorsika

For engineering lenses like the WD437, Zorsika benchmarks each item against the original optical specifications (focal length, throw ratio, lens elements). The lens coating process is identical, delivering sharp imaging without soft edges, and is ready for direct installation.

Zorsika's equivalent replacement model is compatible with 4 Shenzhou Yunkee models: CX-L670U, CX-LU662, CX-L678U, CX-L620U; enter WD437 in the query system on the Zorsika official website to view the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens elements matched to original specifications
• Resolution Testing: Each unit tested before shipment, MTF data available for review
• Coating Process: Lens coating at the same grade as the original, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based delivery

Bottom line: the lens is the optical core—don't gamble with picture quality over a price difference. Zorsika projector lenses are manufactured according to original optical drawings, offering overall better value.

Note: Actual imaging performance depends on the projector body condition and installation environment. For bulk orders, it is recommended to obtain one unit for on-site testing first.

Frequently Asked Questions

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are manufactured according to original optical drawings, with lens elements, coatings, and throw ratio all benchmarked item by item. Each unit undergoes resolution testing before shipment. Compared to OEM lenses, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, optical performance is backed by actual data.

Q: Can this lens replace the original?

A: The lens is the core of the projector's light path, directly determining clarity and color accuracy. Zorsika lenses (models listed in the specifications table above) are benchmarked against original optical parameters (focal length, throw ratio, lens elements) item by item, with identical lens coating process, delivering sharp imaging without soft edges. Ordinary replacement lenses often use regular glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift at a glance. For engineering and exhibition scenarios, Zorsika is the recommended priority.

Q: My machine is not on the 4-model list above. Can I use the WD437?

A: The list represents verified models, not all compatible models. Projectors from the same brand and generation often share lens interfaces. Take photos of the machine nameplate and original lens and send them to Zorsika technical support for confirmation to be extra safe.

Q: Is there an installation guide for the WD437?

A: Yes. The lens removal and installation steps are essentially consistent across Shenzhou Yunkee models. Contact Zorsika sales to obtain illustrated or video instructions for the specific model.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human damage (such as impacts, water ingress, unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the shipping document date.

Lens Routine Maintenance Tips

• Power off before replacing the lens: Be sure to shut down and wait for the cooling fan to stop completely before removing or installing the lens, to avoid damaging the connectors with live operation.
• Do not touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel when handling; do not touch the glass. For dust, use an air blower to gently blow it off—do not wipe with a dry cloth.
• Lock tight after focusing: After the lens is seated, perform a focus test first, then tighten the mounting screws. This prevents image drift caused by loosening over extended use.
• Keep the interface clean: Dust accumulation on the bayonet mount and contacts can lead to poor connection. Cleaning during lens replacement is a good practice.
