Zorsika SZ20G(Electric) Projector Lens for DHN DU10K DU12K BU120 BU100 GU110 BU9600 OEM Compatible

The SZ20G (Electric) is a lens compatible with engineering projectors from brands such as DHN. This article compiles its list of 6 compatible projector models and selection considerations.

Lens Specifications at a Glance

The above specifications are sourced from the Zorsika product database. For the full technical datasheet, please contact our sales team.

Where It Fits: List of 6 Compatible Models (With Specifications)

The following are verified compatible models for the SZ20G (Electric) (DHN projectors), each with brightness, resolution, and zoom ratio:

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

Same Specifications, Why Choose Zorsika

For engineering lenses like the SZ20G (Electric), Zorsika benchmarks each item against original optical parameters (focal length, throw ratio, lens groups), uses consistent lens coating processes, delivers sharp imaging with no edge softness, and is ready to use right out of the box.

Zorsika's equivalent replacement lens is compatible with 6 DHN models including DU10K, DU12K, BU120, BU100, and GU110; entering SZ20G (Electric) in the search system on the Zorsika official website will display the full list of compatible models.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original parameters
• Resolution Testing: Each unit individually tested before shipment; MTF data available upon request
• Coating Process: Lens coatings on par with original quality, reducing light loss
• Stable Supply: Supports bulk procurement and project-based supply

In short: The lens is the optical core—don't gamble picture quality for a price difference. Zorsika projector lenses are manufactured to original drawings, offering an overall stronger value proposition.

Note: Actual imaging performance may be affected by projector condition and installation environment. We recommend testing one unit before bulk procurement.

What to Keep in Mind When Replacing the Lens?

• Power Off Before Replacing the Lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface from live operation.
• Don't Touch the Glass: Fingerprints and oil can directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower for dust and avoid dry wiping with a cloth.
• Focus Before Tightening: After installation, test the focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the Interface Clean: Dust on the mount and contacts can cause poor connectivity; cleaning them during lens replacement is a good practice.

Frequently Asked Questions

Q: My projector isn't on the list of 6 models above. Can I still use the SZ20G (Electric)?

A: The list covers verified models but isn't exhaustive. Engineering projectors of the same brand and generation often share the same lens mount. For a definitive answer, send photos of the model nameplate and original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the original one?

A: The lens is the core of the projection optical path and directly determines sharpness and color. Zorsika lenses (model shown in the spec table above) are benchmarked item by item against original optical parameters (focal length, throw ratio, lens groups), use consistent coating processes, and deliver sharp imaging with no edge softness. Generic replacement lenses often use ordinary glass with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition applications, Zorsika is the recommended choice.

Q: Why choose Zorsika instead of the original?

A: Zorsika lenses are manufactured to original optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit undergoes resolution testing before shipment. Compared to original lenses, we offer shorter lead times and better overall value; compared to other replacement lenses, our optical quality is backed by data.

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

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

Q: Is there an installation guide for the SZ20G (Electric)?

A: Yes. The lens removal and installation steps for DHN models like these are largely consistent. Contact Zorsika sales to get illustrated or video instructions for your specific model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human damage (e.g., drops, water ingress, unauthorized disassembly), please contact after-sales service directly. The warranty period is based on the shipping document date.
