19.8mm QBH Protective Cap

The QBH protective cap plays a crucial role in fiber laser cutting machines by safeguarding the laser's crystals and output window. It acts as a barrier against dust, dirt, and other contaminants during the cutting process, preserving the laser's performance and stability. Additionally, it protects the laser from damage inflicted by metal splashes and other impurities, thereby prolonging its service life. Constructed from high-quality materials with properties like high-temperature resistance, corrosion resistance, and wear resistance, the QBH protective cap effectively shields the laser. It also works in harmony with other components of the laser cutting machine, like optical fibers and lenses, to guarantee the quality and stability of the laser beam.
