The beam expanding lens is a lens assembly that can change the diameter and divergence Angle of the laser beam of the laser cutting machine. The main function of goggles is to protect lenses. Today, I will share with you the knowledge of laser cutting machine accessories, hoping to attract your attention and let you have a deeper understanding of laser cutting machine.
Beam magnifying lens: A beam expander is a lens assembly that changes the laser beam diameter and divergence Angle of the laser cutting machine. The main function of protective glasses is to prevent debris from flying and damaging the lens or the operator. Reflections can be reduced by coating both surfaces with a highly damaged anti-reflection film. The replacement cycle of the protective lens is generally 3 months or depending on the actual situation.
In a laser system, there are usually only one or two transmission optical elements, usually used as the output mirror of the laser cavity and the focusing lens at the end. On the other hand, in some other laser systems, there may be five or more reflective lenses. As a rear-view mirror and a folding mirror, the rear-view mirror is used to control the beam steering and beam transmission system in the laser cavity.
Copper nozzles help to spray gas quickly, effectively preventing impurities such as molten stains from bouncing upward, thus protecting the focusing lens. At the same time, the size of the gas diffusion area can be controlled, which will affect the cutting quality of the laser cutting machine. At the same time, the aperture size of the nozzle varies according to the thickness of the cutting material. The replacement period is usually about two months.
