What is the role of the beam expander and field lens of the optical component?
Speaking of the laser beam expander is actually two lenses of different focal lengths. When laser equipment is used for long-range illumination or projection Cheap Sony Michel Jersey , as well as focusing system related aspects. An important part of the optics optics is called a laser beam expander, which plays an important role. [url= ]VUV grade LiF optics[url] What is the role of a beam expander as an indispensable optical component in an optical component system? It is a lens assembly that is capable of changing the diameter and divergence of the laser beam. The main change is now: one is to reduce the divergence angle of the laser beam; the other is to expand the diameter of the laser beam. The divergence angle of a beam of expanded beam can be focused less when compared to an unexpanded beam. The use of a beam expander with a spatial filter makes the asymmetric beam distribution symmetrical and makes the light energy distribution more uniform. The laser device mainly has a component device called a field lens. Simply put, it is to determine the scope of laser operation of optical components. It is mainly used to focus the light from the galvanometer on a plane. The standard is mainly used as the production range of 110*110mm. Field mirrors are also available in 50*50, 70*70 Cheap Isaiah Wynn Jersey , 110*110, 140*140, and 180*180mm ranges. When the power of the optical component is constant, the addition of the scene causes the energy of the laser to be irradiated onto the surface of the object to be correspondingly weakened Cheap Derek Rivers Jersey , thereby affecting the processing accuracy and quality.

The wavelength of the CO2 optical element is 1064 mm, which has no effect on metal products, so in laser processing, this also selects the scene size according to the situation.
