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 semiconductor marking machine Q head, the purpose is to form a uniform size of the laser beam over the entire marking plane focused spot, laser marking machine is the most important accessory one. Field lens can be divided into f-theta lens and telecentric lenses. Due to the high costs and expenses telecentric lens for industrial applications in laser marking machine is mainly used F-theta lens. In the absence of deformation, the position of the focal point and the tangential focal length of the lens depends on the deflection angle, the position of the focusing point 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, 220mmX220mm Gucci Q crystal where to sell, 300mmX300mm, 400mmX400mm Rui Yang Laser specializes in the supply and maintenance of Han's Laser, Laser Everbright, Golden Laser, Jia Tai laser, laser-laser, laser and other brands Morio Laser marking machine accessories.
