Zorsika WE290 ( < 10K Lumens) Projector Lens Compatible Models: Optoma INU7324 ITU3630 ITU3689

Picture too small or installation distance not enough? A different lens solves it. WE290 (<10K Lumens) fits 18 Optoma models — see the list below.

WE290 (<10K Lumens) Compatible Projector Models (18 total, with brightness/resolution/zoom ratio)

Below are the verified compatible models for WE290 (<10K Lumens) (Optoma 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 depends on the chassis interface and optical structure. For models not listed, contact Zorsika technical support for confirmation.

Frequently Asked Questions

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

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

Q: My projector isn't in the list of 18 models above — can I use WE290 (<10K Lumens)?

A: The list covers verified models, but it isn't exhaustive. Engineering projectors of the same brand and generation often share the same lens interface. To be safe, send a photo of the nameplate and the original lens 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 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 plain glass elements with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are produced according to the original optical drawings, benchmarked item by item for lens group, coating and throw ratio, and each unit undergoes a resolution test before leaving the factory. Compared with the original manufacturer, lead times are shorter and the overall value is better; compared with other replacement lenses, optical quality is backed by data.

Q: How long is the lens warranty?

A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-human 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.

What Zorsika Lenses Offer You

WE290 (<10K Lumens) is a commonly used lens for projects. Zorsika benchmarks it item by item against the original parameters, and each unit undergoes a resolution test before leaving the factory, so optical quality is backed by data.

Zorsika's equivalent replacement model fits 18 Optoma models including INU7324, ITU3630, ITU3689, IPU4791, ZU750 and more; enter WE290 (<10K Lumens) in the query system on the Zorsika official website to see the complete model compatibility list.

• Optical benchmarking: focal length, throw ratio and lens group matched to original parameters
• Resolution testing: each unit tested before shipment, with MTF data available
• Coating process: lens coatings on par with the original, reducing light loss
• Stable supply: supports bulk purchasing and project supply

In short: the lens is the optical core — don't gamble on picture quality to save a few bucks. Zorsika projector lenses are produced according to the original drawings and offer a better overall value.

Note: Actual imaging performance depends on the projector's condition and the installation environment. Before bulk purchasing, we recommend getting 1 unit for a hands-on test.

What to Watch Out for When Changing a Lens

• Power off before changing 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 while powered.
• Don't touch the lens elements: Fingerprints and oil directly affect image quality. Hold the lens by the barrel, not the glass; use an air blower to gently remove dust, and don't wipe with a dry cloth.
• Focus first, then tighten: After installation, do a focus test first, then tighten the fixing screws, to avoid picture drift from loosening over time.
• Keep the interface clean: Dust buildup on the mount and contacts causes poor contact — cleaning it while changing the lens is a safer bet.
