Laser Control Module


EtherCAT Laser Control Module


LCM is an EtherCAT slave module that enables ACS Controllers and Control Modules to control a laser source directly with full synchronization to motion, resulting in highest quality laser micro-machining and optimal throughput.
It is able to interface with a wide range of lasers designed for processing and machining applications such as DPSS, CO2, excimer, fiber, Q-switched, picosecond, femtosecond, and more.
