he information process of Laser Pointer

The so-called Peltier effect is the phenomenon of galvanic DC current through two semiconductor materials, the end of the endothermic, exothermic one end. Heavily doped N-type and P-type bismuth telluride semiconductor material used for the TEC, bismuth telluride components using power series and parallel heat. TEC P-type and N-type (group), they are linked together through the electrode and sandwiched between two ceramic electrodes. The information process of Laser Pointer will be implemented by the information management department.
TEC components on each side of the ceramic electrodes to prevent the laser die short-circuit caused by TEC circuit; TEC temperature control up to 30 ℃ -40 ℃, when there is current TEC flows, the current generated heat from the TEC side to another side of the "hot" side and "cold" side of the TEC, which is the heating and cooling principle of the TEC. It is the green star  laser pointer with keychain
Range of market applications of laser processing equipment industry as well as domestic laser shows set to occupy, prepare production companies are still in relatively early stages of development. Prepared by the production companies are still in relatively early stages of development. Our opportunity and challenge A Chinese laser industry to develop three major factors: the development of China's laser industry, three major factors: an industrial policy to promote three major factors: Since January 2009, the State Council have passed the car, equipped with the system since January, the State Council has successively through the cars, made the top ten industrial revitalization plan, matched and arranged a number of major science and technology. Laser made the top ten industrial revitalization plan, matched and arranged a number of major science and technology. It is the protection goggles of high power  laser pointer .
Processing technology has been supported by the state and promote the application of a high-tech, especially the political and processing technology has been supported by the state and promote the application of a high-tech, the government stressed the need to revitalize the manufacturing sector. Government stressed the need to revitalize the manufacturing sector. The Chinese government has been the laser as advanced manufacturing technology as the Chinese government has been the laser as an advanced manufacturing technology "as advanced manufacturing technology development of national key projects.
