Laser trimming

The laser trimming systems from 4CS-Laser have been designed to meet our requirement. The modular system has pulsed laser sources with different wavelengths and innovative optical components. In addition, it has a freely programmable (open source) software designed to meet the individual customer requirements. The laser system can easily take on any kind of trimming tasks and operate at a hight throughput. It can also be used for mark substrates with number or abstract patterns, such as company logo, for example.
