Customizable Diameter and Focal Length Collimating Lens for Laser Accessories

Fiber laser cutting system is generally used for cutting metal or non-transparent materials with medium or high power laser.The general optical path system and beam transmission sequence are: collimating and expanding the laser from laser QBH or other types of transfer joint through collimating lens to make it parallel light.Then the parallel light is focused at the working position by using the focusing lens.At the same time,there is a protective lens behind the collimating and focusing lenses to prevent the spatters from damaging the collimating and focusing lenses during the cutting process. In the L-shaped cutting head,a 45 degree lens is placed behind the collimating lens to deflect the collimating beam 90 degrees into the focusing mirror for focusing.
