On September 4th, the Northwest Oilfield introduced the “laser foreign matter removal instrument” for the first time to realize live operation and improve work efficiency by more than three times. While improving the reliability of power supply, it reduced the risk of manual operation and human and material cost, and further ensured the operation of oilfield power grid. Safety, the introduction of this equipment is the first time in Xinjiang.
According to reports, the laser pointer foreign matter removal instrument can remotely, quickly and accurately eliminate foreign objects within 200 meters by laser technology. According to the type of foreign matter characteristics, lasers with specific power and band can be set to effectively act on non-metallic materials in the grid. The foreign object is ablated and melted by remote heating to let it fall naturally, and has the advantages of maintenance-free operation and high cost-effectiveness. At the same time, it will not cause damage to the equipment. It is safe, fast and can be charged. It is suitable for the removal of non-metallic foreign objects, branches, horse cells and other objects on most overhead lines.
The laser foreign matter removal instrument completely solves the shortcomings of the traditional live working or power failure manual operation and high safety risk, improves the elimination efficiency, and ensures the safe and stable operation of the overhead transmission line and the power grid.
Changguang Huaxin builds the first complete line of VCSEL laser chips in China
Today, 3D face recognition has become a "standard" feature for high-end smartphones. This feature is inseparable from 3D sensors, and the most important core component of 3D sensors is the VCSEL laser chip.
At present, Changguang Huaxin, located in Suzhou High-tech Zone, has successfully developed VCSEL laser chips and mass production in small quantities, and this production line is also the only complete production line in China.
Wang Jun, chief technology officer of Changguang Huaxin, said that the most important thing about 3D sensing is the distance measurement by laser. The laser needs the light source first, and the VCSEL laser chip produced by the company can provide such a light source, so it is also the core of 3D sensing technology. In the core.
Previously, many processes of VCSEL laser chips had to be completed in the UK and other places, and they were expensive. After the localization of the whole production line, the complete chip can be manufactured in Suzhou, the cost of the enterprise is reduced by 4 times, and the production capacity is increased by 10 times.
Changguang Huaxin is one of the few companies in the world that is the only company in China that develops and mass-produces high-power semiconductor laser chips. At the beginning of this year, the company also cooperated with Suzhou High-tech Zone to build the Semiconductor Laser Innovation Research Institute. The plan has been completed and is expected to be completed and put into use in the second half of next year.
