Zorsika WJ240 Projector Lens for SML-LD1500U SML-L1700U SML-L1300U Compatible Original

WJ240 is a lens compatible with engineering projectors from brands such as Seemile. This article compiles a list of its 3 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 3 Compatible Models (with Specifications)

Below are the verified compatible models for WJ240 (Seemile 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 this list, please contact Zorsika technical support for confirmation.

Why Choose Zorsika

Zorsika provides OEM-spec replacement lenses for WJ240, with key specifications benchmarked item by item against the original, and supports bulk project procurement and supply.

Zorsika's OEM-spec replacement model is compatible with 3 models including Seemile SML-LD1500U, SML-L1700U, and SML-L1300U; enter WJ240 in the Zorsika official website query system to view the complete compatible model list.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original specifications
• Resolution Testing: Each unit tested before leaving the factory, with MTF data available
• Coating Process: Lens coatings at the same grade 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 manufactured 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 obtaining 1 unit for actual testing.

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 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 without touching the glass; use an air blower to gently remove dust, and do not wipe dry with a cloth.
• Focus first, then tighten: After installing in place, perform a focus test first, then tighten the fixing screws, to avoid image drift from loosening during 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 machine isn't on the list of 3 models above. Can I use WJ240?

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 take photos of the body nameplate and the original lens and send them to Zorsika technical support for confirmation.

Q: Can the lens replace the original one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (see the specification table above for the model) are benchmarked item by item against the original optical specifications (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no soft edges; ordinary replacement lenses often use standard glass elements with insufficient coating layers, making brightness loss and color shift immediately noticeable. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

A: Zorsika lenses are manufactured to original optical drawings, with the lens group, coatings, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared to the original, delivery 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 screen size?

A: First confirm the model's lens interface and optical axis position, then select 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 WJ240 come with installation instructions?

A: Yes. The lens removal and installation steps for Seemile 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 shipment document.
