One Table to Understand Zorsika WD304 Projector Lens (Compatible with 2 Models)

When choosing a lens for an engineering projector, always verify compatibility with the projector model first. The complete compatibility list for the WD304 is provided in this article.

Lens Specifications

The above specifications are sourced from the Zorsika product database. For the full technical datasheet, please contact our sales team.

WD304 Compatible Projector Models (2 models, with brightness/resolution/zoom ratio)

The following are verified compatible projector models for the WD304 (Rollei projectors), each with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for final confirmation); lens compatibility is determined by the projector's mount interface and optical structure. For models not listed, please contact Zorsika technical support for verification.

Why Choose Zorsika

For engineering lenses like the WD304, Zorsika benchmarks each item against original optical parameters (focal length, throw ratio, lens groups). The lens coating process is consistent, delivering sharp images with no edge blur, ready to install and use.

Zorsika offers equivalent replacement lenses compatible with 2 models including Rollei RL-D6Q and RL-D7U; enter WD304 in the search system on the Zorsika official website to view the full compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original parameters
• Resolution Testing: Each lens individually tested before shipment, MTF data available
• Coating Process: Lens coatings on par with original quality, reducing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: the lens is the optical core — don't gamble on image quality to save a few dollars. Zorsika projector lenses are manufactured to original drawings, offering an overall advantage.

Note: Actual image performance may vary depending on projector condition and installation environment. We recommend testing one unit before bulk procurement.

Frequently Asked Questions

Q: Why choose Zorsika instead of the original brand?

A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratio benchmarked item by item, and each lens undergoes resolution testing before shipment. Compared to original lenses, we offer shorter lead times and better overall value; compared to other replacement lenses, our 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 accuracy. Zorsika lenses (model shown in the specification table above) are benchmarked against original optical parameters (focal length, throw ratio, lens groups), with consistent coating quality, delivering sharp images with no edge blur. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: My projector is not in the 2-model list above. Can I use the WD304?

A: The list covers verified models but is not exhaustive. Engineering projectors of the same brand and generation often share the same lens mount. For a safer approach, send photos of the projector nameplate and original lens to Zorsika technical support for confirmation.

Q: Is there an installation guide for the WD304?

A: Yes. The lens removal and installation steps for Rollei projectors are largely consistent. Contact Zorsika sales to obtain illustrated or video instructions for your specific model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-man-made damage (e.g., impact, water ingress, unauthorized disassembly), please contact after-sales service directly. The warranty period is based on the shipping date on the delivery document.

Lens Daily Maintenance Tips

• Power off before lens replacement: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with power on.
• Do not touch the lens elements: Fingerprints and oil can directly affect image quality. Hold the lens barrel, not the glass; use an air blower for dust, and never wipe with a dry cloth.
• Tighten after focusing: After installation, test focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the mount clean: Dust on the bayonet and contacts can cause poor connectivity; clean them when replacing the lens for added reliability.
