FAQ
Q: What if the lens doesn't match the screen size?
A: First verify the projector's lens interface and optical axis position, then select a lens with the appropriate throw ratio based on your actual installation distance. If you're unsure, send us the installation distance and screen dimensions—Zorsika technical support will help you find the right recommendation.
Q: My projector isn't on the list of 1 model. Can I still use WD623?
A: The list represents verified models, not a complete range. Engineering projectors from the same brand and generation often share lens interfaces. Send photos of your machine's nameplate and original lens to Zorsika technical support for confirmation.
Q: Can this lens replace the OEM lens?
A: The lens is the core of the projection optical path and directly determines image clarity and color accuracy. Zorsika lenses (models listed in the specifications table above) are engineered to match OEM optical parameters item by item—focal length, throw ratio, and lens elements—with consistent lens coating processes for sharp imaging without edge softness. Standard replacement lenses typically use ordinary glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the preferred choice.
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens groups, coatings, and throw ratios matched item by item. Each lens undergoes resolution testing before shipment. Compared to OEM, we offer shorter lead times and better overall value. Compared to other replacement lenses, our optical quality is backed by data.
Q: What is the lens warranty period?
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 calculated from the date on the shipping invoice.
Same Specs, Why Choose Zorsika
For engineering lenses like the WD623, Zorsika benchmarks each optical parameter (focal length, throw ratio, lens elements) against the original manufacturer's specifications, with matching lens coating technology for sharp imaging and crisp edges, ready to install and use.
Zorsika's equivalent replacement model is compatible with 1 projector model including the Densen DU9150; enter WD623 in the Zorsika official website search system to find the complete model compatibility list.
- Optical Benchmarking: Focal length, throw ratio, and lens elements matched to original manufacturer specs
- Resolution Testing: Each unit tested before shipment, MTF data available
- Coating Technology: Lens coating at the same grade as OEM, minimizing light loss
- Stable Supply: Supports bulk procurement and project-based orders
In short: The lens is the optical core—don't compromise on image quality for a price difference. Zorsika projector lenses are manufactured according to original manufacturer drawings, delivering overall superior advantages.
Note: Actual imaging performance may vary depending on projector condition and installation environment. For bulk orders, we recommend requesting one unit for testing first.
What to Watch for When Replacing a Lens
- Disconnect Power First: Always power off and wait for the cooling fan to stop completely before removing or installing a lens. Avoid working on powered equipment to prevent interface damage.
- Don't Touch the Glass: Fingerprints and oils directly affect image quality. Hold the lens by the barrel without touching the glass. Use an air blower for dust—never wipe with cloth.
- Focus Before Tightening: After positioning, test focus first, then tighten the mounting screws. This prevents loosened screws over time from causing image drift.
- Check Interface Cleanliness: Dust on bayonet mounts and contacts can cause poor connection. Clean them when replacing the lens for better reliability.
