Zorsika WK291 Projector Lens for SML-L2300U SML-L2000U Compatible Original

WK291 is a lens compatible with engineering projectors from brands such as Smile, and this article compiles its list of 2 compatible projector models and selection notes.

Lens Specifications at a Glance

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

Where It Works: List of 2 Compatible Models (with Specifications)

The following are the verified compatible models for WK291 (Smile 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

WK291 is a commonly used lens for projects. Zorsika benchmarks each item against the original factory specifications, and every unit undergoes resolution testing before leaving the factory, ensuring optical quality backed by data.

Zorsika's same-spec replacement model is compatible with Smile SML-L2300U, SML-L2000U, and other 2 models; enter WK291 in the Zorsika official website query system to find the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to original factory specifications
• 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 purchasing 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, offering comprehensive advantages.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk purchasing, 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 by operating with power 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, and do not wipe dry with a cloth.
• Focus before tightening: After installation, test focus first, then tighten the fixing screws, to avoid image drift from loosening over long-term use.
• Keep the interface clean: Dust accumulation on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer approach.

Frequently Asked Questions

Q: My projector isn't on the list of 2 models above — can I use WK291?

A: The list contains verified models, but it doesn't represent all. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to take a photo of the model nameplate and the original lens and send it 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, directly determining clarity and color. Zorsika lenses (see the specification table above for the model) benchmark each item against the original factory optical parameters (focal length, throw ratio, lens groups), with consistent lens coating processes, delivering sharp imaging with no blurry edges; ordinary replacement lenses often use ordinary glass elements with insufficient coating layers, making brightness loss and color shift obvious at a glance. 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 lens groups, coatings, and throw ratios benchmarked item by item, and every unit undergoes resolution testing before shipment. Compared to the original factory, delivery is 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 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 WK291 come with installation instructions?

A: Yes. The lens removal and installation steps for Smile 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 impacts, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
