Zorsika SC261 Projector Lens Compatible with LG BU70QGA, OEM Replacement

The projector lens directly determines image size and clarity. The SC261 covers 1 LG model; before replacing the lens, check the list to confirm compatibility.

Specifications of This Lens

The above parameters come from the Zorsika product database. For the complete technical specification sheet, please contact sales.

Compatible Models: 1 LG Projector (with Brightness, Resolution, Zoom Ratio)

The following are the verified compatible models for the SC261 (LG 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 body interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.

What Zorsika Lenses Offer You

For engineering lenses like the SC261, Zorsika benchmarks each item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes — sharp imaging, no blurry edges, ready to use upon installation.

Zorsika's equivalent-spec replacement model is compatible with LG BU70QGA and 1 other model; enter SC261 in the Zorsika official website query system to find the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
• Resolution Testing: Each unit tested before leaving the factory, with MTF data available
• Coating Process: Lens coating at the same level as the original, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In short: the lens is the optical core — don't gamble on image quality to save a few bucks. Zorsika projector lenses are produced according to original factory drawings, offering comprehensive advantages.

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

What to Watch Out for When Replacing a Lens

• Power off before replacing the lens: Be sure to shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface while powered on.
• Don't touch the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust — do not wipe dry with a cloth.
• Focus before tightening: After installation, perform a focus test first, then tighten the fixing screws, to avoid image drift from loosening over long-term use.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer practice.

Frequently Asked Questions

Q: My machine isn't on the list of 1 model above — can I use the SC261?

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 the original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the original one?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model numbers as in the specification table above) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes — sharp imaging, no blurry 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 scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are produced according to original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared to the original, delivery is faster 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 image size?

A: First confirm the model's lens interface and optical axis position, then choose a lens with the corresponding 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 SC261 come with installation instructions?

A: Yes. The lens removal and installation steps for LG models like this are basically 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-caused 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 shipping document.
