Fused Silica Fiber Laser focusing lens For Laser Cutting and Welding Head
Focusing Lens:
Similar to other laser systems for metal processing applications, the main role of the focusing lens is to concentrate the energy of the laser beam output to spot at a specific distance (focal length) - depending on the application. The focal length - defined by the radius of curvature of the lens - is the most important feature of a focusing lens.
Advantage Of Laser Focus Lens
●High Purity Fused Silica
●Standard High Efficiency
●Low Loss Anti-reflectance
●Double-sided AR coating process, High transmittance
Typical Applications Of Laser Focus Lens
Applicable to YAG laser cutting,laser welding, laser cladding systems etc.
