Rui Yang Laser specializes in the supply and maintenance of Han's Laser, Everbright laser, three laser, Golden Laser, Jia Tai laser, laser-laser, laser and other brands Morio laser marking machine parts and services. Field lens, f-theta focusing lens, the lens system is a professional laser engraving the word aim a laser beam to form a uniform size over the entire marking plane focal spot, it is one of the most important parts laser marking machine. Field lens can be divided into f-theta lens and telecentric lens. Since telecentric lens costs and costly iphone5s laser engraving, laser marking machine for industrial applications mainly used in F-theta lens. In the absence of deformation depends on the position of the focal point of the lens focal length and the tangent of the deflection angle, the focal point position depends only on the focal length and the deflection angle, thus simplifying the calculation method of the focus location. Specifications are divided into: 50mmX50mm, 100mmX100mm, 160mmX160mm laser engraving, 220mmX220mm, 300mmX300mm, 400mmX400mm laser engraving is doing? Professional problem to professional people to answer, then laser engraving is doing on this issue by the professional laser processing factory Rui Yang to answer you because Rui Yang Laser Technology Co., Ltd. in the industry has nearly 10 years of technical experience I believe with such a nature that it should be able to answer the following is laser sharp Yang summed up the experience based on 10 years of experience: With the rapid development of photonics technology panel laser engraving, laser engraving technology range more widely, carving precision increasingly demanding. Effect of laser engraving four fundamental elements are: engraving speed, laser power, engraving precision materials. On the specific material such as to achieve a certain effect engraving, requires absorb some energy laser, this energy should be seen as a material to absorb the laser energy = laser power / engraving speed. Simply put is to improve the material absorbs the laser energy, we should raise or lower the laser power engraving speed, As for the final which method depends on the material and the final engraving effect. In general, users will avoid the high and low speed, because it would reduce production efficiency. In fact, not only affect the efficiency of engraving engraving speed, precision carving also because they have a very big impact.
