About Mergenthaler Laser
Dr. Mergenthaler GmbH & Co. KG develops and manufactures components and systems for laser material processing. The family-owned company was founded in 1991 and has its headquarters with development and production in Neu-Ulm in Bavaria. Products include diode laser modules, laser heads, high-speed pyrometers, and the pyrometer-controlled laser process control system LASCON®, which is installed in more than 3,800 laser systems worldwide. Main applications are laser soldering, laser plastic welding, laser hardening, laser cladding, vacuum heating, and Laser Assisted Bonding. In its own application laboratory with 200-W diode lasers, desktop robots, galvo scanners, and pyrometers, manufacturing processes are developed, and pilot series and contract manufacturing are carried out. In addition, the company offers installation, training, as well as calibration and maintenance of systems and pyrometers. Customers come from the semiconductor industry, electronics manufacturing, automotive, medical technology, photovoltaics, and research; references include Daimler, Robert Bosch, Osram, CERN, and ETH Zurich. A sales office in Shenzhen serves the Chinese market.

Materials and Processes
Diode laser (200 W, LM04 module)
Self-developed laser sources as the basis of temperature-guided processing systems.
High-speed 2-color quotient pyrometer (10 kHz)
Non-contact temperature measurement from 250 °C to 3300 °C, independent of emissivity, with fiber optic cable and integrated closed-loop controller.
Laser soldering
Temperature-guided, flux-free soldering with solder wire feeder SWF200 (0.5–1.2 mm wire diameter).
Laser plastic welding
Contour or quasi-simultaneous welding with galvo scanner for plastic components.
Laser hardening
Temperature-controlled hardening of tools and metal components with compensation of absorption and edge effects.
Laser Cladding (LMD, DED, EHLA)
Laser deposition welding of wear-protection coatings with uniform track width through temperature control.
Laser Assisted Bonding
Temperature-controlled preheating of silicon for eutectic bonding.
Vacuum heating
Heating of samples in high vacuum, e.g., during X-ray structure analysis.
