Zorsika FA105 Projector Lens Compatible Models: Dihao DU21K DU22K DU26K OEM Compatible

FA105 is a lens compatible with engineering projectors from brands such as Diheng. This article compiles a list of its 3 compatible projector models and selection notes.

Specifications

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

FA105 Model Compatibility List (3 models total, with brightness/resolution/zoom ratio)

The following are verified compatible models for the FA105 (Diheng projectors), with brightness, resolution, and zoom ratio listed for each:

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.

Same Specifications, Why Choose Zorsika

The FA105 is a commonly used lens for projects. Zorsika benchmarks each item against the original factory parameters, performs resolution testing on every unit before shipment, and guarantees optical quality with data.

Zorsika's equivalent replacement model is compatible with Diheng DU21K, DU22K, DU26K, and other 3 models; enter FA105 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 factory parameters
• Resolution Testing: Every unit tested before shipment, with traceable MTF data
• Coating Process: Lens coatings at the same level as the original factory, 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 manufactured according to original factory drawings and offer comprehensive advantages.

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

What to Watch Out for When Replacing a Lens

• Power off before replacing the lens: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop, to avoid damaging the interface from live operation.
• 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 approach.

FAQ

Q: My projector isn't on the list of 3 models above — can I use the FA105?

A: The list covers verified models, but it doesn't represent all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take photos of the nameplate and the original lens and send them to Zorsika technical support for confirmation.

Q: Can the lens replace the original factory one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers as in the specification table above) are benchmarked item by item against original factory optical parameters (focal length, throw ratio, lens group), with the same lens coating process, 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 scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original factory?

A: Zorsika lenses are manufactured according to original factory optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and every unit undergoes resolution testing before shipment. Compared to the original factory, 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 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 FA105 come with installation instructions?

A: Yes. The lens removal and installation steps for Diheng models like these are basically the same. Contact Zorsika sales to obtain illustrated or video instructions for the corresponding 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.
