Protection window of laser cutting machine

We have the best protective windows to protect focusing lens against contamination. Our protective window is a barrier (debris shield) between the lens and the metal sheet. The protection windows are used to prevent the back-reflection, and also help to seal the laser cutting head. It prevent dust and fume to enter the inner optics.


  • A high degree of purity
  • Superior environmental durability
  • A low coefficient of thermal expansion
  • Outstanding resistance to thermal shock
  • Excellent transmission from the UV to the NIR
