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

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

Note: Brightness, resolution, and zoom ratio are sourced from the Zorsika product database (subject to the model's nameplate/manual); 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 matches each parameter according to the original manufacturer's specifications and performs resolution tests on every unit before shipment, ensuring optical quality with verifiable data.

Zorsika's equivalent replacement model is compatible with 3 Diheng models: DU21K, DU22K, and DU26K. Enter FA105 in the query system on the Zorsika official website to find the complete list of compatible models.

• Optical Matching: Focal length, throw ratio, and lens group are matched to original manufacturer parameters.
• Resolution Testing: Each unit is tested before shipment; MTF data is available.
• Coating Technology: Lens coating is equivalent to the original manufacturer's grade, minimizing light loss.
• Stable Supply: Supports bulk purchasing and project supply.

In summary: The lens is the optical core—don't gamble on image quality for a price difference. Zorsika projector lenses are produced according to original manufacturer blueprints, offering a comprehensive advantage.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For bulk purchases, it is recommended to first obtain one unit for testing.

What to Note When Replacing a Lens?

• Power off before replacing the lens: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface with live operation.
• Avoid touching the lens elements: Fingerprints and oil directly affect image quality. Hold the lens by the barrel, not the glass. Use a blower for dust; do not wipe dry with a cloth.
• Tighten after focusing: After installation, perform a focus test first, then tighten the fixing screws to prevent image drift from loosening over time.
• Keep the interface clean: Dust on the mount and contacts can cause poor connections. Clean them when replacing the lens for reliability.

Frequently Asked Questions

Q: My projector is not on the list of 3 models above. Can I use the FA105?

A: The list includes verified models but is not exhaustive. Projectors of the same brand and generation often share lens interfaces. For a more reliable confirmation, send a photo of the projector's nameplate and the original lens to Zorsika technical support.

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

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model see specifications table above) are matched to original optical parameters (focal length, throw ratio, lens group) item by item, with consistent coating technology, resulting in sharp imaging without soft edges. Generic replacement lenses often use ordinary glass with insufficient coating layers, leading to noticeable brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are produced according to original optical blueprints, with item-by-item matching for lens group, coating, and throw ratio, and each unit undergoes resolution testing before shipment. Compared to the original manufacturer, delivery is shorter and overall value is better. Compared to other replacement lenses, optical quality is backed by verifiable data.

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

A: First, confirm the projector'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 for a recommendation.

Q: Does the FA105 come with installation instructions?

A: Yes. The lens removal and installation steps for models like Diheng are generally consistent. Contact Zorsika sales to obtain illustrated or video instructions for the 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-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
