Compatible Models: 3 Ricoh Projectors (with Brightness, Resolution, Zoom Ratio)
The following are verified compatible models for WB012 (Ricoh projectors), each with brightness, resolution, and zoom ratio:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| PJ YX620 | 5000 lumens | 1024×768 XGA | 1.6X |
| PJ YW620 | 5000 lumens | 1280×800 WXGA | 1.6X |
| PJ YU620 | 5000 lumens | WUXGA 1920×1200 | 1.6X |
Note: Brightness, resolution, and zoom ratio are sourced from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is determined by the body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.
What the Zorsika Lens Offers You
WB012 is a commonly used lens for projects. Zorsika benchmarks each parameter against the original factory specifications and performs resolution testing on every unit before shipment, ensuring optical quality is backed by data.
The Zorsika equivalent replacement lens is compatible with 3 Ricoh models including PJ YX620, PJ YW620, and PJ YU620; enter WB012 in the Zorsika official website query system to view the full list of compatible models.
- Optical Benchmarking: Focal length, throw ratio, and lens groups are matched to original factory parameters
- Resolution Testing: Every unit is tested before shipment, with MTF data available for review
- Coating Technology: Lens coatings are on par with the original factory, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In short: The lens is the optical core — don't gamble with image quality over price differences. Zorsika projector lenses are manufactured to original factory drawings, offering a comprehensive advantage.
Note: Actual imaging performance is affected by the projector body condition and installation environment. We recommend testing 1 unit before bulk procurement.
What to Note When Replacing the Lens?
- Power off before replacing 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 with live operation.
- Don't touch the lens glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel and avoid touching the glass; use a 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 loosening over time that could cause image drift.
- Keep the interface clean: Dust on the mount and contacts can cause poor connection; cleaning them during lens replacement is a safer practice.
Frequently Asked Questions
Q: My projector is not in the 3 models listed above. Can I use WB012?
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 confirmation, send a photo of the nameplate and original lens to Zorsika technical support.
Q: Can the lens replace the original one?
A: The lens is the core of the projection optical path and directly determines sharpness and color. Zorsika lenses (model shown in the specification table above) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens groups), with consistent coating technology, delivering sharp images without edge softness; ordinary replacement lenses often use standard glass with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition scenarios, Zorsika is the recommended choice.
Q: Why choose Zorsika instead of the original?
A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and every 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: What if the lens doesn't match the image size?
A: First confirm the lens mount and optical axis position of your model, then select a lens with the appropriate 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 WB012 come with installation instructions?
A: Yes. The lens removal and installation steps for Ricoh models like these are essentially the same. 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 (such as impact, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
