What Zorsika Lenses Can Give You

SA19B is a commonly used lens for projects. Zorsika performs parameter-by-parameter alignment according to original manufacturer specifications, and each lens undergoes resolution testing before shipment, ensuring optical quality with documented data.

Zorsika's equivalent alternative model is compatible with 4 Christie models: DWU760-iS, DWU860-iS, DWU960-iS, and 4K860-iS. Enter SA19B in the query system on Zorsika's official website to find the complete model compatibility list.

• Optical Alignment: Focal length, throw ratio, and lens elements matched to original manufacturer specifications
• Resolution Testing: Each unit tested before shipment, MTF data available for review
• Coating Process: Lens coating at the same level as original manufacturer, minimizing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: The lens is the optical core—don't gamble with picture quality over price differences. Zorsika projector lenses are manufactured according to original manufacturer optical blueprints, offering overall better value.

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

What to Watch Out for When Replacing a Lens?

• Disconnect power before lens replacement: Always power off and wait for the cooling fan to stop before lens removal or installation. Avoid live operation to prevent interface damage.
• Don't touch the lens elements: Fingerprints and oils directly impact image quality. Grip the lens barrel without contacting the elements. Use an air blower for dust, never wipe with cloth.
• Lock focus before securing: After proper installation, test focus first, then tighten the mounting screws to prevent long-term loosening and image drift.
• Keep connectors clean: Dust accumulation on bayonets and contacts causes poor connectivity; clean during lens replacement for better reliability.

Frequently Asked Questions

Q: My model isn't on the list above. Can I use SA19B?

A: The list contains only verified models, not an exhaustive compilation. Same-brand projectors from the same generation often share lens interfaces. Send photos of the projector nameplate and original lens to Zorsika technical support for confirmation.

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

A: The lens is the core of the projection light path and directly determines sharpness and color accuracy. Zorsika lenses (models in the specification table above) are aligned item-by-item with original manufacturer optical parameters (focal length, throw ratio, lens elements). The lens coating process is consistent, producing sharp images 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 the original manufacturer?

A: Zorsika lenses are manufactured according to original manufacturer optical blueprints, with lens elements, coatings, and throw ratios aligned item-by-item. Each lens undergoes resolution testing before shipment. Compared to original manufacturer lenses, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, Zorsika provides documented optical quality assurance.

Q: The lens doesn't match the screen size. What should I do?

A: First verify the projector's lens interface and optical axis position, then select a lens with the appropriate throw ratio based on actual installation distance. If uncertain, send the installation distance and screen dimensions to Zorsika technical support—we'll help you select the right lens.

Q: Does SA19B come with installation instructions?

A: Yes. Lens removal and installation procedures for Christie models are essentially consistent. 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 include a 12-month warranty. Normal use and non-human damage (such as impacts, water exposure, or unauthorized disassembly) can be addressed directly through after-sales service. Warranty period is calculated from the shipping document date.
