Frequently Asked Questions

Q: What if the lens doesn't match the screen size?

A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the corresponding throw ratio based on the actual installation distance. If you're unsure, send the installation distance and screen dimensions to Zorsika Technical Support and we'll help you choose.

Q: My machine isn't on the list of 16 models above. Can I use LB021?

A: The list represents verified models but isn't exhaustive. Projectors of the same brand and generation often share lens interfaces. Send photos of the machine nameplate and the 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 system and directly determines clarity and color accuracy. Zorsika lenses (models shown in the specifications table above) are itemized to match OEM optical parameters (focal length, throw ratio, lens elements), with consistent lens coating processes, delivering sharp images without soft edges. Regular replacement lenses often use standard glass elements with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.

Q: Why choose Zorsika over OEM?

A: Zorsika lenses are manufactured according to OEM optical blueprints, with lens elements, coatings, and throw ratios matched item by item, and each unit 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.

Why Choose Zorsika

For engineering lenses like the LB021, Zorsika matches OEM optical parameters (focal length, throw ratio, lens elements) item by item, with consistent lens coating processes, delivering sharp images without soft edges, ready for installation.

Zorsika equivalent replacement models are compatible with 16 models including SIPA, Blue Shield Cardon, INESA and others such as SP-L10X, SP-L10W, SP-L20X, SP-L20W, SP-L20U. Enter LB021 in the query system on the Zorsika official website to find the complete model compatibility list.

• Optical Matching: Focal length, throw ratio, and lens elements matched to OEM specifications
• Resolution Testing: Each unit tested before shipment with verifiable MTF data
• Coating Process: Lens coatings match OEM grade to minimize light loss
• Stable Supply: Supports bulk procurement and project-based orders

Bottom line: The lens is the optical core — don't gamble with image quality over a price difference. Zorsika projector lenses are manufactured to OEM blueprints with better overall value.

Note: Actual imaging performance depends on projector condition and installation environment. We recommend obtaining one unit for testing before bulk procurement.

What to Watch Out for When Replacing the Lens

• Power off before lens replacement: Be sure to shut down and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with live操作.
• Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel without touching the elements. Use an air blower to gently remove dust; do not wipe with cloth.
• Focus before tightening: After positioning the lens, test focus first, then tighten the mounting screws to prevent image drift from loosening during extended use.
• Keep the interface clean: Dust on bayonet mounts and contacts can cause poor connection; clean them during lens replacement for reliability.
