【High Quality】Superb double-sided solid coating. Precision slicing, polishing, grinding. Resistant to high temperature, excellent optical properties; long working life, high working efficiency.
Package includes: 1 x Lens
Product Features:
1. We use advanced zinc selenide material produced from Saxonburg, excellent lens materials directly determine the stability of the laser system, strong laser-enhanced lenses, accurate focal length, abrasion resistance of the film layer, high luminous flux, greatly improve work efficiency.
2. The spot light is stable, the cutting and engraving effect is good, the high power density can be endured and the surface film layer is firm, hard to fall off, and resistant to rubbing. Double-sided AR coating, cylindrical polishing increases the amount of light transmitted through these components, reducing or eliminating stray light in the system.
3. The stability of the pad position is improved, some applications are cut, engraving speed is increased, and the ability to withstand reflection back is improved. Better cleaning resistance, improved service life, and better handling of radioactive coatings.
Lens Installation:
The convex lens of the focusing lens is mounted upwards. After replacing the lens, the lens barrel needs to be finely adjusted up and down, and it is fixed in the best effect position.
Please pay attention to the following points when using, prevent the lens from bursting and extend the life of the lens:
a. The machine's air-cooling failure causes the lens to overheat and burst, or the air-cooling is not smooth. Condensation in the lens barrel causes the lens to burst;
b. The lens has a reverse spray or liquid of the engraved material. If the lens is burst due to uneven heating for a long time, it is necessary to clean it with a cotton swab dipped in absolute alcohol in time;
c. When adjust the light path, the light path hits the junction of the lens edge and the lens barrel, which may cause burst.
Transport:
We will provide a safe and reliable packaging, the damages in the transport link will be compensated by our part.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $7 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for TEN-HIGH products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
