BTHOCING High Precision Optical Lens Dia18/19.05/20mm ZnSe CO2 Laser Focus Lens for Laser Cutting/Engraving Machines
CO2 laser focusing lenses are widely used in laser machining (cutting, drilling, welding, engraving, etc.) and various laser systems. To meet the demand of the market, our company has developed two types of products: Plano convex and meniscus lenses. We have various dimension of plano convex lenses in stock. If you need meniscus lenses, please feel free to inquire with us.
