ZnSe Focus lens D18/19//20mm Optical Lens for CO2 Laser
We offer D18/19/20/25/38.1 ZnSe focus lens. with different focal length
More suitable for high turnover cutting applications, and when the cost is more important than the level of accuracy.
When Co2 laser cut steel and other thick materials, a Co2 laser Plano-convex lens provides a greater cut width, enabling the laser's oxygen assist gas to aid the cutting process.
