Zorsika WK164 Projector Lens Compatible Models: Roly RL-D6Q Roly RL-D7U OEM Compatible

When replacing the lens on an engineering projector, the biggest fear is buying one that won't fit. This article explains in one go which Roly models the WK164 supports and what to watch out for when selecting it.

WK164 Compatible Model List (2 models total, with brightness/resolution/zoom ratio)

The following are verified compatible models for the WK164 (Roly 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 this list, please contact Zorsika technical support for confirmation.

You May Want to Ask

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

A: First confirm the model's lens interface and optical axis position, then select 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 projector isn't on the list of 2 models above. Can I use the WK164?

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

Q: Can this 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 consistent lens coating processes, delivering sharp imaging with no blurring at the edges. Ordinary replacement lenses often use standard 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 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 undergoes resolution testing 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, non-human-caused damage (such as impacts, 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.

Same Specifications — Why Recommend Zorsika

Zorsika provides an original-specification replacement lens for the WK164, benchmarked item by item against the original manufacturer's key parameters, with support for bulk project procurement and supply.

Zorsika's same-specification replacement model is compatible with 2 models including the Roly RL-D6Q and RL-D7U; enter WK164 in the query system on the Zorsika official website to find the complete compatible model 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 one sentence: The lens is the optical core — don't gamble on image quality to save a few dollars. 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, it's recommended to get 1 unit for actual testing first.

What to Watch Out for When Replacing the Lens

• Power off before replacing 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 operating 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 glass. 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 in place, do a focus test first, then tighten the fixing screws to avoid image drift from loosening over long-term use.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer approach.
