Focus Lens for Laser Welding Machine
Product Inroduction
Focus lens is one of the core accessories of fiber laser engraving machine and cutting machine, marking machine, welding machine and other laser equipment. The function is to form a uniform focus point on the entire standard plane. Its main performance indicators are: focal length and scanning range. The focus position depends on both the focal length and the declination angle; The spot diameter is proportional to the focal length, that is, when the scanning area reaches a certain level, the larger the spot diameter obtained.
The focus lens is an optical element that can compress the divergent laser light in the angular direction. Due to the large launch surface of the fiber, it is a diffuse beam rather than a collimated or focused spot. The fiber laser focusing mirror can effectively converge the beam at the end of the fiber and control the output beam in a small area.
Products Details
1. The substrate is made of imported quartz crystal, which has excellent optical, thermal and mechanical properties.
2. Excellent double-sided antireflection coating can reduce laser loss and the permeability can reach 99.6%.
3. After cutting,grinding,polishing and other processes the substrate has high temperature resistance and strong laser resistance.
