Zorsika WB018 Projector Lens Compatible with Daoxing DJ-70H01, OEM Replacement

The projector lens directly determines image size and clarity. The WB018 covers 1 Doshine model. Before replacing the lens, check the list to confirm compatibility.

Lens Specifications at a Glance

The above specifications come from the Zorsika product database. For the complete technical datasheet, please contact sales.

Compatible Models: 1 Doshine Projector (with Brightness, Resolution, Zoom Ratio)

The following are the verified compatible models for the WB018 (Doshine projectors), with brightness, resolution, and zoom ratio listed for each:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (subject to the model nameplate/manual). Lens compatibility is based on the body interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.

Why Choose Zorsika

For engineering lenses like the WB018, 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 blurring at the edges — ready to use upon installation.

Zorsika's equivalent-spec replacement model fits 1 model including the Doshine DJ-70H01; enter WB018 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 coatings at the same grade as the original, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In a nutshell: 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, offering a comprehensive advantage.

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

What to Watch Out for When Replacing a Lens

• Power off before replacing 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 with a dry cloth.
• Focus first, then tighten: After installation, 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 bet.

Frequently Asked Questions

Q: My projector isn't on the list of 1 model above — can I use the WB018?

A: The list covers verified models, not 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 this lens replace the original one?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model shown in the specification table above) benchmark each 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, resulting in visible brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

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

Q: What if the lens doesn't match the image size?

A: First confirm the model's lens interface and optical axis position, then choose a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: Does the WB018 come with installation instructions?

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

Q: How long is the lens warranty?

A: All Zorsika projector lenses come with a 12-month warranty. For 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.
