Zorsika WD304 Projector Lens Compatible Models: Roly RL-D6Q Roly RL-D7U OEM Compatible

When matching a lens to an engineering projector, check the projector model first. This article lists all compatible models for the WD304.

Lens Specifications

The above parameters are from the Zorsika product database. For the complete technical specification sheet, please contact sales.

WD304 Model Compatibility List (2 models total, with brightness/resolution/zoom ratio)

The following are verified compatible models for the WD304 (Lely 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 projector nameplate/manual for accuracy); lens compatibility is based on the body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.

Why Choose Zorsika

For engineering lenses like the WD304, Zorsika benchmarks each 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 upon installation.

Zorsika's equivalent-spec replacement model is compatible with 2 projector models including Lely RL-D6Q and RL-D7U; enter WD304 in the Zorsika official website query system to view the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
• Resolution Testing: Each unit tested before shipment, 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 manufactured to original drawings and offer comprehensive advantages.

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

Frequently Asked Questions

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are manufactured to original optical drawings, with lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before shipment. Compared to the original, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.

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 numbers shown in the specification table above) are benchmarked item by item against 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, resulting in visible brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: My projector isn't in the list of 2 models above — can I use the WD304?

A: The list covers verified models but does not represent all possibilities. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to send photos of the projector nameplate and original lens to Zorsika technical support for confirmation.

Q: Does the WD304 come with installation instructions?

A: Yes. The lens removal and installation steps for Lely projectors are basically the same. Contact Zorsika sales for illustrated or video instructions for your specific model.

Q: What is the lens warranty period?

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.

Routine Lens Maintenance Tips

• Power off before changing the lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface while powered on.
• Don't touch the lens elements: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. Use an air blower to gently remove dust — do not dry-wipe with a cloth.
• Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws to avoid image drift from loosening over time.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor connections. Cleaning them while changing the lens is a good practice.
