Lens Specifications at a Glance

The above specifications come from the Zorsika product database. For a complete technical datasheet, please contact sales.

Compatible Models: 78 Optoma, Sonnoc, Keyingda and Other Projectors (with Brightness, Resolution, Zoom Ratio)

The following are verified compatible models for the BX-CTA15 (Optoma, Sonnoc, Keyingda and other projectors), each listed with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is based on the chassis interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.

What Zorsika Lenses Offer You

Zorsika provides original-specification replacement lenses for the BX-CTA15, with key parameters matched item by item to the original. Bulk project procurement and supply are supported.

Zorsika same-specification replacement model, compatible with Optoma, Sonnoc, Keyingda and other brands including MNU990, MSU611, MWU636, MEU890, MNU653 and 78 other models; enter BX-CTA15 in the Zorsika official website query system to find the complete compatible model list.

• Optical matching: Focal length, throw ratio, and lens groups matched to original specifications
• 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: Bulk procurement and project supply supported

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 drawings and offer a comprehensive advantage.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing.

What to Watch Out for When Replacing a Lens

• Power off before replacing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface with live power.
• Don't touch the glass: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. Use an air blower to gently remove dust — do not wipe with a dry cloth.
• Focus before tightening: After installation, perform a focus test first, then tighten the mounting 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 replacing the lens is a safer practice.

Frequently Asked Questions

Q: My projector isn't in the 78-model list above — can I use the BX-CTA15?

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 photos of the model nameplate and original lens to Zorsika technical support for confirmation.

Q: Can the lens replace the original?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers in the specification table above) are matched item by item to original optical parameters (focal length, throw ratio, lens groups), with identical lens coating processes — delivering sharp imaging with 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 applications, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratios matched 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: What if the lens doesn't match the screen size?

A: First confirm the model's lens interface and optical axis position, then select a lens with the appropriate throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support and we'll help you choose.

Q: Does the BX-CTA15 come with installation instructions?

A: Yes. The lens removal and installation steps for Optoma, Sonnoc, Keyingda and similar models are essentially 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), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
