Lens Specifications Overview

The above parameters are sourced from the Zorsika product database. For complete technical specifications, please contact your sales representative.

Compatible Models: 2 Ricoh Projectors (Brightness, Resolution, Zoom Ratio Included)

The following are verified compatible models for WJ149 (Ricoh projectors), with brightness, resolution, and zoom ratio for each unit:

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

Why Choose Zorsika at the Same Specifications

For engineering lenses like the WJ149, Zorsika aligns each optical parameter (focal length, throw ratio, lens group) with OEM specifications, with consistent lens coating for sharp imaging without edge blur, ready for installation.

Zorsika equivalent replacement model, compatible with Ricoh PJ RU7700L, PJ RU8800L, and other 2 models; enter WJ149 in the query system on Zorsika's official website to find the complete compatible model list.

• Optical Alignment: Focal length, throw ratio, and lens group match OEM specifications
• Resolution Testing: Each unit tested before shipment, MTF data available
• Coating Process: Lens coating matches OEM grade, reducing light loss
• Stable Supply: Supports bulk purchasing and project-based supply

In short: The lens is the optical core—don't compromise image quality for a price difference. Zorsika projector lenses are manufactured according to OEM drawings, offering overall superiority.

Note: Actual imaging performance depends on the projector condition and installation environment. It is recommended to test one unit before bulk purchase.

What to Watch Out for When Replacing the Lens?

• Always power off before replacing the lens: Make sure to turn off the machine and wait for the cooling fan to stop completely before removing or installing the lens, to avoid damaging the connectors with live operation.
• Do not touch the lens glass: Fingerprints and oils directly affect image quality. Hold the lens by the barrel, not the glass. If there is dust, gently blow it off with an air blower—do not wipe with a dry cloth.
• Lock after focusing: After positioning the lens, test the focus first, then tighten the securing screws. This prevents the image from drifting due to loosening over time.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor connections—clean them during lens replacement for better reliability.

Frequently Asked Questions

Q: My machine is not on either of the two lists above. Can I use the WJ149?

A: The lists contain only verified models, not the complete range. Projectors from the same brand and generation often share lens interfaces. Take a photo of the machine nameplate and the original lens and send them to Zorsika technical support for confirmation.

Q: Can this lens replace the original manufacturer's lens?

A: The lens is at the core of the projector's optical system and directly determines clarity and color accuracy. Zorsika lenses (models listed in the specs table above) are matched item by item against original optical parameters (focal length, throw ratio, lens elements), with consistent lens coating processes, producing sharp images without edge softness. Ordinary replacement lenses often use regular glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are manufactured according to original optical blueprints, with lens elements, coatings, and throw ratios matched item by item. Each unit undergoes resolution testing before shipment. Compared to original manufacturers, Zorsika offers shorter lead times and better overall value. Compared to other replacement lenses, Zorsika guarantees optical performance with data to back it up.

Q: What if the lens does not match the image size?

A: First confirm the lens interface and optical axis position for your projector model, then select a lens with the appropriate throw ratio based on the actual installation distance. If you are unsure, send the installation distance and screen dimensions to Zorsika technical support and we will recommend the right lens.

Q: Is there an installation guide for the WJ149?

A: Yes. Lens removal and installation steps are essentially the same across Ricoh and similar projector models. Contact Zorsika sales for illustrated or video guides specific to your model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human-induced damage (such as impacts, water ingress, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is calculated from the date on the shipping invoice.
