SIGMA LS Laser Micromachining Subsystem

Femtosecond laser-integrated module designed for processing versatility.


AMADA WELD TECH, Inc. (Monrovia, CA) announced the release of the SIGMA LS Laser Micromachining Subsystem, a femtosecond laser-integrated module ideal for precision micromachining of metals and metal alloys, polymers, ceramics and glasses.

With its small form factor and integration-ready design, the SIGMA LS is ideal for:

  • Machine builders
  • System integrators
  • Contract manufacturers
  • Job shops
  • R&D laboratories

SIGMA LS offers processing solutions for a broad range of femtosecond laser micromachining applications requiring optimal quality, minimal thermal effects and high stability and dimensional accuracy including:

  • Hole drilling in stainless steel cannula.
  • Selective polymer ablation on metal.
  • Hole drilling in ceramic microfluidics.
  • Texturing metals, polymers and ceramics.
  • Micromachining polymer filter screen.
  • Micromachining metal struts and filaments.

The ready-to-integrate subsystem features pre-installed sensitive laser and optical components, delivered with an optimized application and laser process.

AMADA WELD TECH provides on-site installation support and application training, as well as tooling and part handling guidance.

SIGMA LS is available with femtosecond laser options from 5 to 40 watts and both infrared (IR) and green wavelength options. Both air-cooled and water-cooled laser options are available.

Features include:

  • Control panel for communications
  • Sensitive optical components to prevent contamination
  • Galvanometer scan head with multiple lens options for beam delivery
  • Scanner and laser control software with a GUI tailored to the application

Also available are an optional fixed-optic focus head and on-axis (through-the-lens) and off-axis vision options. A rigid aluminum structure with a protective sheet metal enclosure ensures system robustness.
