Reflective lenses (also called mirrors or reflective optics) in laser welding machines are used to redirect, shape, or split the laser beam. These components are essential in both beam delivery systems and scan heads, especially in high-power fiber laser welding setups.

• Unlike transmissive lenses (which focus the beam by bending it), reflective lenses use mirrors to:

  • Steer the laser beam (e.g. in robotic arms or galvo systems)

  • Split or combine beams

  • Handle very high laser powers without distortion or thermal lensing
