Principles of remote control green laser pointer

Laser cutting process parameters and their laws ※ laser power: laser cutting, the size of the required power is determined by the material properties and cutting mechanism. * Cutting speed: under the conditions of a certain power, the greater the plate thickness, the smaller the cutting speed. The cutting speed also have a greater impact on the incision surface roughness. ※ beam quality, focal length lens and the defocus amount: the laser output beam mode for the fundamental transverse mode of the laser cutting is the most favorable. The spot size is proportional to the focal length of the focusing lens. Short focal length lens can be smaller spot, but the depth of focus is very small. Defocus amount must remain the same cutting speed and cutting depth greater impact, cutting process, the general choice of negative defocus amount, the focus position on the cutting board surface below a certain point. Principles of remote control green laser pointer will be introduced at first.
Polysilicon manufacturing is the first side of the photovoltaic industry chain, is the bottleneck in the development of restrictions on China’s PV industry. Some enterprises in China began to enter the polysilicon production is expected to excessive dependence on foreign countries in the next few years the situation has changed. Grand (Yangzhou) Environmental Protection Equipment Manufacturing Co., Ltd. PV industry market analysis, industry chain midstream. Please do not change the emitter and receiver of green laser pointer or it couldn’t work normally.Flatten wafer supply solar grade silicon ingots, silicon rods, silicon manufacturing is the second component of the photovoltaic industry chain. The wire cutting capacity and supply of raw materials is the key of the wafer production.
But the high price of 95 percent on export only. Grand (Yangzhou) Environmental Protection Equipment Manufacturing PV industry market analysis of the components of downstream components of the industrial chain rapid expansion of manufacturing low barriers to entry, low value-added products. In the entire solar photovoltaic industry chain, component manufacturing due to less investment, short construction period, the technology and low capital threshold, the nearest market characteristics have attracted a large number of manufacturing enterprises, is the fastest growing photovoltaic industry chain link a. It is estimated that China has more than 600 manufacturers of solar modules. And the main manufacturers of the products have passed the TǘV, UL and other international certification.
