19mm QBH Protective Cap

The QBH protective cap is an important protective device used in fiber laser cutting machines. It primarily protects the laser's crystals and output window. During the laser cutting process, the protective cap prevents dust, dirt, and other impurities from entering the laser's interior, thereby maintaining the laser's performance and stability. At the same time, it also safeguards the laser from damage caused by splashing metal particles and other impurities, extending the laser's service life.

The QBH protective cap is typically made of high-quality materials that possess characteristics such as high-temperature resistance, corrosion resistance, and wear resistance, effectively protecting the laser. Furthermore, the QBH protective cap is usually used in conjunction with other components of the laser cutting machine, such as optical fibers and lenses, to ensure the quality and stability of the laser beam.
