Aerotech’s (Pittsburgh, PA; Enhanced Throughput Module (ETM) improves positioning performance of high-dynamic motion systems by directly measuring unwanted motion of the machine base and communicating it back to the controller for compensation. By working in concert with Aerotech controllers, the ETM allows the servo system to compensate for dynamic motion artifacts and to do a superior job of executing the desired motion path.

A new turnkey reel-to-reel system from Rofin-Baasel (Daventry, Northamptonshire, UK; is targeted at the production of flexible photovoltaic products. This system has been designed to incorporate multiple laser sources, which can be used to perform several different processing tasks on Si, µSi, GIGS, and organic cells, all within a single machine. Built upon a substantial granite base, the system incorporates high-speed, high-precision motorized axes to drive vibration-proof optics when the system is being used in the step-and-repeat mode. For on-the-fly applications, beam positioning is achieved using fast and precise galvo scanning heads. A fully integrated vision system enables precise alignment with fiducials and also enables automated inspection tasks to be carried out within the machine.

Electro Scientific Industries Inc. (ESI; Portland, OR; offers the ML5900 laser micromachining platform, an advanced, high-precision system that is optimized for industrial-production. The system gives users real-time process control while providing them with a modular framework for maximum flexibility and rapid redeployment. Featuring a high-power, interchangeable diode-pumped IR, green, or UV laser, the system enables component and OEM manufacturers to drill, route, and nanostructure a wide range of materials including metals, organics, dielectrics, semiconductors, and hybrid-engineered parts. The platform’s integrated metrology and rotary stage allow for fully parallel processing, thereby increasing the system’s overall speed and handling capabilities.

Surface treatment fiber laser

IPG Photonics (Oxford, MA; has introduced a new series of compact fiber lasers developed specifically for cladding, brazing, annealing, and heat treating applications. The YLS-4000-CL 1 kW to 4 kW fiber laser systems take advantage of the company’s newest diode technology at price levels below what direct diode systems typically cost with benefits only a laser can offer. Features include single wavelength, maintenance free, large dynamic range, plug and play round or square delivery to 1 mm, rapid beam switching, long stand-off distance, and high electrical efficiency.
