The system is ideal for micromachining metals, polymers, ceramics, and glasses.

Amada Weld Tech, a manufacturer of welding, marking, cutting, sealing, and bonding technology, announces 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 the perfect choice for machine builders and system integrators, as well as contract manufacturers, job shops, and 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; and texturing metals, polymers, ceramics. It is also a good choice for micromachining polymer filter screen and micromachining metal struts and filaments.

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

The system features an easy-access control panel for communications with common industrial control systems. Sensitive optical components are contained in a positive pressure environment to prevent contamination. The galvanometer scan head comes with multiple lens options for accurate, high-speed beam delivery and scanner and laser control software is provided 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 aluminium structure with a protective sheet metal enclosure ensures system robustness.
