Focusing lens are used to focus laser beam. The objective of focusing the laser beam is to use the laser power for material processing.

Lenses available:

• ZnSe positive Menicus
  
• ZnSe Plano-convex
  
• Si/Cu reflector & Phase retarder
  
• Ge Cavity Mirror
  
• ZnSe Coupler

Telecentric scanning lenses are a special configuration in which the arrangement of optics is designed to focus down the beam such that it is always perpendicular to the flat field.
This is accomplished by ensuring that the system 'stop' is located at the front focal point of the lens system. The 'stop' is located at the position where the beam is deflected from the axis. In a single-axis scanning system, this location is at the scanning mirror. For two-axis scanning, the stop is mid-way between the mirrors.
