聚焦头

激光通过柔性光纤电缆或固定反射镜传送到工作站。  Typically the laser is delivered to the work piece at a low power density which requires focusing to enable materials processing. The focus is the tool which takes the “raw” laser beam and focuses to a small diameter typically less than 0.04” down to 0.0005”.  

For Nd:YAG and fiber lasers there are a number of different types of focusing heads. Below shows a few options, including a schematic of a 90 degree focus head, showing the collimating lens, the 45˚ reflector, focusing lens and cover slide; a 90˚ focus head; and an in-line focusing head. Selection will be based on the application, space and budget.

使用Nd:YAG和光纤激光的巨大优势在于  聚焦头上可以安装一个串联式摄像头,用以提供焊接区的画面。   这使得操作人员能够看到焊接点,提供了一种使用可视系统的方法,可判断激光是否聚焦在零件上。
