focus lens -10.6µm
1.Singlet focusing lens --10.6μm
There are two main types of CO2 laser focusing lenses commonly used: plano-convex lenses and concavo-convex lenses.
Anti-Reflection Coating，AR/AR Coating @ 10.6µm＆650nm。

2.Doublet focusing lens-10.6μm
Compared with the singlet Focusing lens ,The focusing spot of the doublelet Focusing Lens more tiny .It has higher energy density.It can meet the need of precision processing such as cutting. It has a high transmittancefor laser and good heat dissipation,so can be used for high power laser.
