The inspection principle of laser pointer

These five constitute the standard model of laser marking machine. The actual needs of different users, together with the different shape of structure, fixture tooling tailored software systems to form complete laser marking solutions. Relative to the pneumatic marking, galvanic corrosion, the mark of the screen printing, inkjet printer, mechanical engraving, laser marking has the following advantages: laser processing for light contact, non-mechanical contact, there is no mechanical stress, it is particularly suitable for use in high hardness such as cemented carbide, high brittleness (such as solar silicon), high melting point and high precision (such as precision bearings) require particularly high occasions. Energy density of laser processing, time is short, small heat affected zone, thermal deformation, thermal stress is small, does not affect the internal electrical properties. For quality control of green laser pointer  needs many working personnel.
532μm, 355μm, 266μm laser cold, suitable for precision machining of special materials. Direct burning laser etching, permanent markers, non-erasable, the failure will not be deformed off suitable security Cuanhuo and product traceability requirements. Laser processing system is a computer system, convenient layout, modify, jump number, random codes, only code requirements, suitable for personalized processing, batch processing of small quantities more advantage. Mark the effect of fine craft beautiful, high precision, can enhance product quality, higher value added products. Linewidth can be as small as 10μm, depth of up to 10μm or less, can be marked on the surface of the parts of the millimeter size. The personnel of inspecting green laser pointer need to know some basic knowledge.
Low supplies, non-polluting, energy saving and environmental protection, in line with European environmental standards, in line with the GMP requirements of the pharmaceutical industry. Low processing costs. One-time investment in expensive equipment, but continuous, the large number of processing and finally to the processing costs of each of the parts lower down. Flexible processing methods. Internal workpiece through a transparent medium for processing, easy-oriented focus, to achieve the direction to transform easily in conjunction with the numerical control system. The laser is divided into solid-state lasers (yttrium aluminum garnet YAG and yttrium vanadate YVO 4), gas lasers (He-Ne laser, CO2 laser) categories. Carbon dioxide (CO2) laser marking machine, CO2 gas as the activation medium, light waves emitted infrared region 10600nm. The inspection personnel of green laser pointer should know something about the mathematical statistics.
Such lasers have two different forms. Pulsed lasers. Mask method, short pulses of laser energy to produce marks or graphic. But because of the different tags require different obstacles, and change the mark to take a long time. Continuous laser. Light pen form, only one level, the technology less demanding, low-cost, simple equipment, but the output is high energy, high efficiency, is widely used in plastics laser marking printing. Yttrium aluminum garnet laser marking machine. The laser emits near-infrared region of 1060nm light waves activate the media is a solid, continuous, light pen two different intensity of the laser beam by changing the output energy can be obtained. And at the same time, the inspection personnel should know the inspection principle of   laser pointer .
