LASER in Experiment, R & D, and Production with ADwin

As a freely programmable signal generator, ADwin is ideally suited for beam control. Any curve shape can be stored in the memory, processed with the CPU and output via the analog or digital outputs. The superposition of path information and point information is easily possible by adding different signal sources.

Scanning Electron Microscope

ADwin systeme are used in different types of scanning microscopes like laser, scanning tunnel, scanning electron beam, scanning force, focused ion beam (FIB) or atomic force microscope (AFM) to control the probe and for detection of the surface structure.

ADwin controls an X-Y position via two analog outputs, at the same time the reflected light is recorded via analog inputs or counters and the result is stored in a scan table. This creates a 2D image in a microsecond grid, point by point and line by line. For spatial representations, a new focus is repeatedly approached via a third analog output and a 3D image is calculated from up to 100 X-Y scans.

Magneto-Optic Traps (MOT)

Under vacuum conditions, a gas volume filled with several thousand atoms can be cooled to a temperature of less than a millionth of a degree above absolute zero. This is achieved with intelligent laser cooling methods and special magnetic atom traps. ADwin systems are used to control such atom traps.

Quality control for Laser Welding

ADwin systems take on quality control during laser welding with intelligent measurement data acquisition and online analysis functions. Directly behind the welding point, the weld seam just being created is recorded with a triangulation sensor and evaluated online in real-time. Deviations such as blowholes etc. are detected and their position is transferred to the laser's path control for post-processing e.g. transmitted via CAN or Profibus.

Material processing with lasers

Laser technology is used for surface processing and surface refinement. In the production of electronic assemblies, laser-trimmable resistors are increasingly used because of their advantages for automation. The material is vaporized with a laser beam and small notches are cut in the resistors. The ADwin system uses fast X-Y position control to move the laser beam over the component while the resistance value is determined at the same time. When the setpoint is reached, the laser beam is switched off..
