Fiber laser cutting machine is a high-precision and high-value equipment, and it has strict requirements during use. One of the key components that affects the precision of machine laser cutting is the focusing and collimating lens,and the installation of the lens is very important. Improper Operation can damage the machine.
When installing, pay attention to the following 2 points:
1.For focusing lens : Biconvex lens is above,Meniscus lens is below,and the side with small convex amplitude is close to the meniscus lens
2.For collimating lens : Biconvex lens is below,Meniscus lens is above,and the side with small convex amplitude is close to the meniscus lens.
