Description: 

BeamWatch AM是一种集成激光测量系统,设计用于测量激光增材制造系统的关键激光束参数。
 
BeamWatch AM能够沿相机视场(FOV)中的光束散焦线同时测量多个轮廓。以视频速率进行实时测量。ֺ包括:

  • 光束腰(焦点)的宽度和位置
  • 焦点漂移
  • 质心
  • M2 或 K值
  • 发散
  • 光束参数产品
  • 瑞利长度
  • 绝对功率

实时性能还能够在激光启动期间测量动态焦移。BeamWatch AM测量技术的理论基础是,当光束通过介质传播时,空气中的氧和氮分子会让激光发生瑞利散射。这种散射光的测量为沿观察视图方向的激光束提供了等效狭缝扫描。利用传统相机和图像捕获系统来测量散射光。BeamWatch AM包括一台用于空间测量的相机以及一个可以对激光功率密度分布进行完整分析的NIST可溯源功率传感器。
 
相机同时且实时观察光束散焦线,包括光束的近场/焦点/远场。该测量技术包括符合ISO 11146标准的传播和M2测量。此外,由于所有测量均实时进行,因此可在启动秒数期间测得所发生的任何焦点漂移并给出报告。

ISO compliance of non-contact, real-time beam analysis

1. IntroductionDuring the past decade laser power levels used in production applications has risen significantly. Today, welding systems are commonly using laser power in the range of multiple kilowatts. To deliver continuously high product quality, the key parameters of the laser beam must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology based on the Rayleigh scattering. The technology used in the BeamWatch laser beam profilers enables the measurement of high-power beams without ever touching the laser beam. As the technology is 阅读更多...
