The green laster pointer technology is widely used

Mainly used for fine engraving purposes. (Argon) is mainly used for physical and chemical use (eg, biotechnology). * Laser engraving machine for the major media? LD (semiconductor) is mainly used for visible laser excitation source and 3 CO2, YVO4 and YAG laser engraving machine the difference between the CO2 laser engraving and YVO4/YAG produce different wavelengths of laser function is that their respective different types of materials suitable for engraving. This must understand the strengths and weaknesses of each laser to choose the best model for your application classification according to the wavelength of the laser engraving machine CO2 Laser Marker 10.6-μm wavelength is often used for engraving paper, plastic, glass and ceramics. The green laster pointer technology is widely used in industrial fields such as electron, car and aerospace.Their 10.6-μm wavelength can be absorbed by a transparent material, making them ideal for the film, such as translucent glass substrate and PCB materials on the engraving. Development of high-power models can be applied moldings so they cut off the gate and PET sheet cutting purposes. YVO4 Laser Marker 1.06-μm wavelength YAG laser engraving machine is often used for engraving metal, plastics and ceramics. Both lasers are ideal for almost all of the material in high contrast engraved marks. Before, conventional wisdom is to choose the YAG laser Marker for the needs of high-power use, and YVO4 Laser Marker fine print for small power.The green laster pointer technology is widely used in metal and nonmetal material processing. However, these high YVO4 laser engraving machines so that they can take over once there are YAG laser applications. Not the visible spectrum ultraviolet (UV) visible spectrum invisible infrared spectrum level of a standard laser engraving machine laser class 1M class at risk? The following chart according to grade, as well as when to use each type of user should pay attention to lists of all levels of the laser. Class defined in the moderate and predictable operating conditions, including the use of optical instruments for beam within the TV, safe laser. Given laser wavelength 302.5nm to 4,000 nm, between the moderate and predictable operating conditions of laser safety, but if the user within the beam using optical equipment can be dangerous.green laster pointer technology could greatly reduce processing time. Class 2 emit visible light radiation in the wavelength between 400nm to 700nm, usually produce repulsive light reaction of the eye protection mechanisms, including the blink reflex of the laser. This reaction can be expected in the moderate and predictable operating conditions, including the use of optical beam within the instrument as to provide adequate protection when. Class 2M emit visible light radiation in the wavelength between 400nm to 700nm, usually produce repulsive light reaction of the eye protection mechanisms, including the blink reflex of the laser. However, if users use of optical devices in the beam, the laser output may look more dangerous.The new technology applied in green laster pointer industry can reduce processing cost. Class 3R laser wavelength 302.5nm issued to 106nm between the direct beam as a potentially dangerous inside, but the risk is lower than Class 3B laser, user adoption of manufacturing requirements and control measures for Class 3B lasers than the lower . Emission limits can be achieved in the 400nm to 700nm in wavelength between two to five times the AEL within the wavelength range and in the other one within five times the AEL. Class 3B Class 4 usually exposed to the dangerous beam inside the laser. (Ie NOHD (nominal visual hazard distance) or less). Diffuse attention is usually safe. At the same time to diffuse laser harmful. They can cause skin burns, but also the formation of a fire.
