The laser beam characteristics of small beam diameter and long focal length combined with high pulse energies (over 2mJ at 10KHZ) and high average powers allows the EV40 to achieve high-speed marking-on-the-fly (MOTF).  Provides average diode life greater than 25,000 working hours, and a mission-specific air-cooled EV-40 platform.  The robust mechanical and optical design allows the EV-40 laser to operate without any chiller in an industrial environment where shock, vibration, and dust are a concern while maintaining stable output power. The small footprint allows for easy integration into manual off-line and automated on-line configurations, making it useful for a wide range of industrial coding and marking applications.
