Parabolic or Aspheric Mirrors are used for beam focusing of all laser power classes and are typically used as the last mirror in the beam guidance system of a laser cutting or welding application. The higher the surface quality and shape accuracy, the better the beam quality reaching the workpiece.

These mirrors are available with or without direct water-cooling and typically have a tough molybdenum coating, or other high quality protective or reflective coating.
