Jun crown laser marking machine gradually adjusted to the beam position farthest from the laser tube and adjust until the mark coincides with the center of the two markers. Repeat until the laser can be taken to the specified location, adjust the laser cutting machine has reached the light path of purpose. Reflective coating on the lenses is a set of high refractive index dielectric film, when the light is directed to a dielectric film, all of the reflected light on the phase interface are the same, so that the wavelength of the light reflection enhancing, both reach the reflected laser protective eyewear purpose, but also to other high permeability of visible light. Composite film consisting of two reflective media, the middle layer of absorbent glass separated by low-cost color laser marking machine lettering, suppress internal reflection between two reflective film unnecessary. Protective glasses for laser performance is better, the safety factor, suitable for medium and high power laser protection. The explosive is coated on the lens can be explosive. When the incident laser intensity reaches a certain value, in order to play shielding laser quickly detonated a role in the military to prevent the laser weapon damage the eyes. Each laser goggles have their own characteristics, generally only one wavelength laser anti-minority can prevent two or more wavelengths of laser light, it must be based on the use of lasers, choose the appropriate laser goggles. Laser light amplification by stimulated emission is an abbreviation. Pump source (incentives) continue to put low-energy particles in the active medium of the order of "pumped" to the high-energy particle level, so that high-energy particle generation inversion of the order, the stimulated emission is generated by the optical resonator resonant cavity laser beam is activated by light to medium zoom, part of the amplified output optical radiation, the formation of a laser. The main properties of the laser beam are: high brightness laser beam: i.e., a high power density of the light, after which the laser beam passes through the focus, can produce thousands or even tens of thousands of degrees at very high temperatures at the focus, so that almost all of the laser light can be processed material has possibilities. High directivity of the laser: high directivity mainly refers to small divergence angle of the laser beam. So that it can be effectively transmitted in a longer distance when the laser focus is still obtained to ensure high power density, which is a necessary condition for laser processing. Highly monochromatic laser: namely wave laser radiation within a small range of optical harmonic, to ensure that the laser can be precisely focused at a focal point to obtain a high laser power density. High coherence laser: In physics, coherence refers to generate significant interference, waves have the properties required. More broadly, laser marking machine selling, for certain properties within Bing association between physical description of wave coherence with their waves, wave and other waves. Coherence describes the phase relationship between the various parts of the laser light waves. Laser is an extremely pure color (with a single frequency), high intensity light, you want to produce a laser, you first need to make in order to make the laser light reflection of light between two mirrors concussion kept so light wear one of them had a "gain medium"; atom such gain medium is excited by the reflection of light photons, emitted photons with the same frequency of the original photon laser marking machine inkjet printer, so the gradual accumulation of form at the same frequency, in the same direction, high intensity laser. Company products include: fiber laser marking machines, semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine, laser inkjet printer and other industrial laser equipment.
