Automated Beam Control in Production with High Brightness Multikilowatt NIR-lasers
The HighPower-MSM-I is designed to work in rough industrial environment: automated beam monitoring in continious working manufacturing facilities.
Application
Beam power, focus position laterally and in depth, focus geometry in form of diameter, divergence and Rayleigh length, beam parameter product and M² as well as further derived parameters can be monitored. The measured values are compared to preset limit- and critical values. Hence, an alarm is generated.
Fully automated measuring programs are running using the communication between system control and laser source. The measuring results are given back to the system control with a corresponding evaluation. All measuring results and status parameter of the measuring decive can be saved with a special timestamp.
Besides an automated beam parameter measurement within a production environment, the device is also suitable for the qualification and verification of beam parameter of beam sources, laser machines and processes in development, production, maintenance and service.
Technical description
The device is provided with a comprehensive internal sensoric for self controlling and for identification of internal malfunction sources. Additionally, a further port for a secondary light conducting cable enables an automatic testing of all measuring functions and the status of the internal optics. A power measurement test can be done due to a corresponding internal heat source.
