Description
GaAs co2 laser cutter focal focus focusing lens, diameter: 18mm /0.71" inch, Focal length: 38.1mm /1.5", Thickness: approximate 3mm / 0.12" inch, Applicable laser power: 80W-500W
High Quality GaAs Material, Excellent optical properties, better quality for using, especially suitable for higher power laser cutter and engraver machine.
High Transmittance: To obtain superior transmittance, GaAs crystals are grown by Chemical Vapor Deposition process.
GaAs material is a chemically inert, non-hygroscopic and highly pure product that has high resistance to thermal shock and stability in virtually all environments, can work under higher temperature and with longer work life.
Double-sided Solid Coating, demonstrates superior CO2 laser transmittance and is employed as the transmission optical components used in CO2 laser processing.
How to Determine Focal Length?
The Focal Length is the Distance Between the Focal Lens and the cutter/engraver Material.
When install the Lens, Make Sure the Focal/Focusing Lens: Convex Face to Laser, Concave Face to Material.
How to Clean Laser Lens and Mirrors?
- Step 1 Cleaning for Light Contamination (dust, lint particles)
Use an air bulb to blow off any loose contaminants from the optic surface before proceeding to the cleaning steps.
- Step 2 Cleaning for Light Contamination (smudges, fingerprints)
Lay the lens tissue on the optic's surface. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, wetting the complete optic's diameter. Without lifting the lens tissue, drag the lens tissue across the optic just fast enough so that the liquid evaporates behind the tissue. This should leave no streaks.
- Step 3 Cleaning for Moderate Contamination (spittle, oils)
Dampen an unused cotton swab or cotton ball with white distilled vinegar. Using light pressure, wipe the optic's surface with the damp cotton. Wipe excess distilled vinegar with a clean dry cotton swab. Immediately dampen a cotton swab or cotton ball with acetone. Gently wipe the optic's surface to remove any acetic acid.

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 $87 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 Mssoomm 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.
