ZnSe Focus lens for CO2 laser cutting

1.The diameter 20mm focus lens uses imported antireflection coating film and make lens’s surface flim fasten and wiping resistance.. The transmittance of 10.6um is more than 99%.

2.This 50.8mm focus lens uses Chinese special grade PVD ZnSe material, double-coated antireflection film and Cylinder polishing technology increase transmittance and reduce or remove the stray light in optics system.

3.This ZnSe focus lens adopts Chinese special grade PVD ZnSe material and uses professional diffraction and aberration design. They can make it has much smaller laser spot and adapts to much larger laser power..
