Air compressors are the basic products of modern industrialization and play an important role in industrial development. In the establishment of China's compressor industry system during the "1st Five-year" period, in order to meet the development needs of national construction and to break through the economic blockade imposed by Western countries on China, the state set up its own scientific research and teaching team and organized the compressor industry plant. Continuously develop new products. In 1959, the first typical product in the series of power piston compressors was developed, marking the development of China-made compressors has entered a good beginning of development. In 1966, China completed the manufacture of the first screw compressor. Because China's national economy is affected by political factors, production efficiency is low, and development is slow, which seriously hampers the development of the compressor manufacturing industry. To change this development situation is that after the reform and opening up, especially at the end of the last century, the development of China's national economy has entered a fast lane, and the original industrial system has been unable to meet the needs of continuous development, which has prompted the developed countries and The manufacturing industries in the region have come to invest and set up factories. At the same time, they have also driven the development of national industries. This makes the market share of screw compressors continue to increase, in addition to its own advantages, but also has a direct relationship with the price of spare parts. In the 20th century, due to technological breakthroughs and the reduction of parts prices, screw compressors have sprung up like mushrooms. The number of manufacturers has exceeded 100, and the manufacture of screw compressors has seen a hundred controversies since then.
Telecentric F-Theta lenses enhance laser scanning systems by providing a focused laser beam perpendicular to the process surface, hence eliminating inconsistencies associated with non-flat surfaces. The Telecentric F-Theta Scanning Lenses feature multiple elements for the ultimate in image resolution incorporated in a special optical configuration to provide a beam perpendicular to the flat field image plane. The air spaced design and high efficiency AR coating guarantee excellent throughput and durability.
Telecentric Scanning lens has special advantages in minimizing distortion and drill angle. It's widely used in critical laser marking applications and drilling holes through a material. A typical application is electronics microvia drilling
