Where It Works: List of 6 Compatible Models (with Specifications)
Below are the verified compatible models for the WB123 (Ricoh projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| PJ RU6708L | 8000 lumens | WUXGA 1920×1200 | 1.6X |
| PJ RU6800L | 8000 lumens | WUXGA 1920×1200 | 1.6X |
| PJ RU6808L | 8000 lumens | WUXGA 1920×1200 | 1.6X |
| PJ RU6700L | 7000 lumens | WUXGA 1920×1200 | 1.6X |
| WUL6680 | 8500 lumens | WUXGA 1920×1200 | 1.6X |
| WUL6690 | 9600 lumens | WUXGA 1920×1200 | 1.6X |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the projector nameplate/manual for accuracy); lens compatibility depends on the body interface and optical structure. For models not on this list, contact Zorsika technical support for confirmation.
Why Choose Zorsika
For engineering lenses like the WB123, Zorsika benchmarks each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes — sharp imaging, no soft edges, ready to use upon installation.
Zorsika's equivalent-spec replacement model is compatible with 6 projector models including the Ricoh PJ RU6708L, PJ RU6800L, PJ RU6808L, PJ RU6700L, and WUL6680; enter WB123 in the Zorsika official website query system to see 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 purchasing and project 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 factory drawings, offering a comprehensive advantage.
Note: Actual imaging performance depends on the projector's condition and installation environment. Before bulk purchasing, we recommend ordering 1 unit for testing.
FAQ
Q: Why choose Zorsika instead of the original manufacturer?
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 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, directly determining clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes — sharp imaging, no soft 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 on the list of 6 models above — can I use the WB123?
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 projector nameplate and original lens to Zorsika technical support for confirmation.
Q: Does the WB123 come with installation instructions?
A: Yes. The lens removal and installation steps for Ricoh projectors of this type 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 damage (such as impact, water damage, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipment document.
Routine Lens Maintenance Tips
- Power off before changing 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 while powered.
- Don't touch the lens elements: Fingerprints and oil directly affect image quality. Hold the lens by the barrel, not the glass. For dust, use an air blower gently — don't wipe dry with a cloth.
- Focus first, then tighten: After installation, do a focus test first, then tighten the fixing screws, to avoid image drift from loosening over time.
- Keep the interface clean: Dust on the mount and contacts can cause poor contact. Cleaning them while changing the lens is a safer practice.
